14 | Each step of this workshop has its companion commit in the git history with a detailed commit message. 15 | 16 | At the end of the workshop, we will have created three applications: 17 | 18 | * `stock-quotes` is a functional WebFlux app which streams stock quotes 19 | * `stock-details` is an annotation-based WebFlux app using a reactive datastore 20 | * `trading-service` is an annotation-based WebFlux app that consumes data from `stock-quotes` and `stock-details` 21 | 22 | Reference documentations can be useful while working on those apps: 23 | 24 | * http://projectreactor.io/docs[Reactor Core documentation] 25 | * https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Flux.html[API documentation for Flux] 26 | * https://projectreactor.io/docs/core/release/api/reactor/core/publisher/Mono.html[API documentation for Mono] 27 | * Spring WebFlux 28 | {spring-framework-doc-base}/spring-framework-reference/web.html#web-reactive[reference documentation] 29 | and {spring-framework-doc-base}/javadoc-api/[javadoc] 30 | 31 | Clone the repository: 32 | 33 | git clone https://github.com/reactor/head-first-reactive-with-spring-and-reactor.git 34 | 35 | We will start off by creating the Trading Service application which gets data from a pre-existing Stock Quotes application. 36 | 37 | == Trading Service application 38 | 39 | === Create this application 40 | 41 | Go to `https://start.spring.io` and create a Maven project with Spring Boot {spring-boot-version}, 42 | with groupId `io.spring.workshop` and artifactId `trading-service`. Select the `Reactive Web` and `Devtools` dependencies. 43 | Unzip the given file into a directory and import that application into your IDE. 44 | 45 | If generated right, you should have a main `Application` class that looks like this: 46 | 47 | [source,java] 48 | .stock-quotes/src/main/java/io/spring/workshop/tradingservice/TradingServiceApplication.java 49 | ---- 50 | include::../trading-service/src/main/java/io/spring/workshop/tradingservice/TradingServiceApplication.java[] 51 | ---- 52 | 53 | Note that, by default, `spring-boot-starter-webflux` transitively brings `spring-boot-starter-reactor-netty` 54 | and Spring Boot auto-configures Reactor Netty as a web server. 55 | 56 | Spring Boot supports Tomcat, Undertow and Jetty as well. 57 | 58 | === Use the WebClient to stream JSON to the browser 59 | 60 | In this section, we'll call our remote `stock-quotes` service to get Quotes from it, so we first need to: 61 | 62 | * copy over the `Quote` class to this application 63 | * add the Jackson JSR310 module dependency 64 | 65 | Create a `QuotesClient` annotated with `@Component` and inject a `WebClient.Builder`. Now, create a method in the `QuotesClient` called 66 | `quotesFeed` which will use the `webClient` to consume the stream of quotes via Server Sent Events (SSE). 67 | 68 | NOTE: There are two ways to use a `WebClient`, directly via the static factory or by injecting the `WebClient.Builder`. 69 | The latter is used by libraries such as Spring Cloud Sleuth that enrich `WebClient` with extra features. 70 | 71 | Now create a `QuotesController` annotated with `@Controller` and inject it with the `QuotesClient`. 72 | Add a method that responds to `"GET /quotes/feed"` requests with the `"text/event-stream"` content-type, 73 | with a `Flux` as the response body. The data can be retrieved from the `quotesFeed` method on `QuotesClient`. 74 | 75 | You can test it by starting both applications. First, start the Stock Quotes application. 76 | It can be started from your IDE or with `mvn spring-boot:run` and it should run a Netty server on port 8081. 77 | You should see in the logs something like: 78 | 79 | [source,bash] 80 | ---- 81 | INFO 2208 --- [ restartedMain] o.s.b.web.embedded.netty.NettyWebServer : Netty started on port(s): 8081 82 | INFO 2208 --- [ restartedMain] i.s.w.s.StockQuotesApplication : Started StockQuotesApplication in 1.905 seconds (JVM running for 3.075) 83 | ---- 84 | 85 | Start the Trading Service application from your IDE or with `mvn spring-boot:run`. This should run a Netty server on port 8080. 86 | 87 | [source,bash] 88 | ---- 89 | INFO 2208 --- [ restartedMain] o.s.b.web.embedded.netty.NettyWebServer : Netty started on port(s): 8080 90 | INFO 2208 --- [ restartedMain] i.s.w.t.TradingServiceApplication : Started TradingServiceApplication in 1.905 seconds (JVM running for 3.075) 91 | ---- 92 | 93 | You can hit http://localhost:8080/quotes/feed to consume the stream of quotes. 94 | 95 | Now, let's create another application that can provide the details for a trading company. 96 | 97 | == Stock Details application 98 | 99 | === Create this application 100 | 101 | Go to `https://start.spring.io` and create a Maven project with Spring Boot {spring-boot-version}, 102 | with groupId `io.spring.workshop` and artifactId `stock-details`. Select the `Reactive Web`, `Devtools` 103 | and `Reactive Mongo` dependencies. 104 | 105 | Unzip the given file into a directory and import that application into your IDE. 106 | 107 | If generated right, you should have a main `Application` class that looks like this: 108 | 109 | [source,java] 110 | .stock-details/src/main/java/io/spring/workshop/stockdetails/StockDetailsApplication.java 111 | ---- 112 | include::../stock-details/src/main/java/io/spring/workshop/stockdetails/StockDetailsApplication.java[] 113 | ---- 114 | 115 | Edit your `application.properties` file to start the server on port 8082. 116 | 117 | [source,properties] 118 | .stock-details/src/main/resources/application.properties 119 | ---- 120 | include::../stock-details/src/main/resources/application.properties[] 121 | ---- 122 | 123 | === Use a reactive datastore 124 | 125 | In this application, we’ll use a MongoDB datastore with its reactive driver; for this workshop, we’ll use an in-memory instance of MongoDB. So add the following: 126 | 127 | [source,xml] 128 | .stock-details/pom.xml 129 | ---- 130 | include::../stock-details/pom.xml[tags=inMemMongo] 131 | ---- 132 | 133 | We'd like to manage `TradingCompany` with our datastore. 134 | 135 | [source,java] 136 | .stock-details/src/main/java/io/spring/workshop/stockdetails/TradingCompany.java 137 | ---- 138 | include::../stock-details/src/main/java/io/spring/workshop/stockdetails/TradingCompany.java[] 139 | ---- 140 | 141 | Now create a `TradingCompanyRepository` interface that extends `ReactiveMongoRepository`. 142 | Add a `findByTicker(String ticker)` method that returns a single `TradingCompany` in a reactive fashion. 143 | 144 | We'd like to insert trading companies in our datastore when the application starts up. For that, create a `TradingCompanyCommandLineRunner` 145 | component that implements Spring Boot's `CommandLineRunner`. In the `run` method, use the reactive repository 146 | to insert `TradingCompany` instances in the datastore. 147 | 148 | NOTE: Since the `run` method returns void, it expects a blocking implementation. This is why you should use the 149 | `blockLast(Duration)` operator on the `Flux` returned by the repository when inserting data. 150 | You can also `then().block(Duration)` to turn that `Flux` into a `Mono` that waits for completion. 151 | 152 | === Create a JSON web service 153 | 154 | We're now going to expose `TradingCompany` through a Controller. 155 | First, create a `TradingCompanyController` annotated with `@RestController` and inject the `TradingCompanyRepository`. 156 | Then add two new Controller methods in order to handle: 157 | 158 | * GET requests to `"/details"`, returning all `TradingCompany` instances, serializing them with content-type `"application/json"` 159 | * GET requests to `"/details/{ticker}"`, returning a single `TradingCompany` instance, serializing it with content-type `"application/json"` 160 | 161 | It can be started from your IDE or with `mvn spring-boot:run` and it should run a Netty server on port 8082. 162 | You should see in the logs something like: 163 | 164 | [source,bash] 165 | ---- 166 | INFO 2208 --- [ restartedMain] o.s.b.web.embedded.netty.NettyWebServer : Netty started on port(s): 8082 167 | INFO 2208 --- [ restartedMain] i.s.w.s.StockDetailsApplication : Started StockDetailsApplication in 1.905 seconds (JVM running for 3.075) 168 | ---- 169 | 170 | Now that we have an application that can return the details for a company with a given ticker, we can update the Trading Service application 171 | to use those details and return a combination of the latest quote for that ticker along with the company's details. 172 | 173 | == Update Trading Service application 174 | 175 | We will first create a service that will use a `WebClient` to get data from the Stock Details application. 176 | Create a `TradingCompanyClient` annotated with `@Component`. 177 | Then add two methods: 178 | 179 | * `findAllCompanies` will return a `Flux` by using the webClient to get data from the `/details` endpoint from the Stock details application 180 | * `getTradingCompany` will return a `Mono` by using the webClient to get data from the `/details/{ticker}` endpoint from the Stock details application 181 | - If no trading company is found for the given ticker, the `Mono` will complete without any data. Instead, we will emit a `TickerNotFoundException` error using the `switchIfEmpty` operator. 182 | 183 | Let's expose the two `TradingCompanyClient` methods with a local `TradingCompanyController`. 184 | 185 | You might have updated an already running `TradingServiceApplication`. Since DevTools is present, you can just recompile to automatically restart the application. 186 | 187 | You can test the new endpoints by hitting: 188 | 189 | * http://localhost:8080/details to list all trading companies 190 | * http://localhost:8080/details/MSFT to get details for a particular ticker 191 | * http://localhost:8080/details/PIZZA to see what happens for an unknown ticker 192 | 193 | Let's add a method called `getLatestQuote(String ticker)` on the `QuotesClient` which will get the latest quote for a given ticker from the quotes feed. 194 | 195 | * Reuse `quotesFeed` to get the actual feed 196 | * Filter the stream of quotes with quotes matching the given ticker 197 | * Take the next matching quote 198 | * If no matching quote is found within 15 seconds, then return a fallback `Quote` for the ticker. 199 | 200 | Now, we want to combine data produced by `stock-quotes` and `stock-details` as a `TradingCompanySummary`. 201 | 202 | Copy the following class to your project. 203 | 204 | [source,java] 205 | .trading-service/src/main/java/io/spring/workshop/tradingservice/TradingCompanySummary.java 206 | ---- 207 | include::../trading-service/src/main/java/io/spring/workshop/tradingservice/TradingCompanySummary.java[] 208 | ---- 209 | 210 | Now, add another method to the `QuotesController` which can handle requests to `/quotes/summary/{ticker}`. 211 | 212 | * Use the `TradingCompanyClient` to get the details for the company with the given ticker 213 | * Create a `TradingCompanySummary` by composing the details with the latest quote from the `QuotesClient` 214 | 215 | TIP: You can compose two reactive results using `Mono.zip(monoA, monoB, biFunction)` or `monoA.zipWith(monoB, biFunction)`. 216 | 217 | We need to handle the `TickerNotFoundException` emitted by the `TradingCompanyClient` as an HTTP 404. 218 | You will need to create a method annotated with `@ExceptionHandler`. 219 | 220 | Again, because of DevTools we can just recompile and test by hitting: 221 | 222 | * http://localhost:8080/quotes/summary/MSFT to get the summary for a particular ticker 223 | * http://localhost:8080/quotes/summary/PIZZA to test the 404 NOT FOUND an unknown ticker 224 | 225 | Now, we will look at creating a functional-style WebFlux application by re-creating the Stock Quotes Application. 226 | Fasten your seatbelt and remove the stock-quotes directory! 227 | 228 | == Stock Quotes application 229 | 230 | === Create this application 231 | 232 | Go to `https://start.spring.io` and create a Maven project with Spring Boot {spring-boot-version}, 233 | with groupId `io.spring.workshop` and artifactId `stock-quotes`. Select the `Reactive Web` and `Devtools` 234 | dependencies. 235 | Unzip the given file into a directory and import that application into your IDE. 236 | 237 | If generated right, you should have a main `Application` class that looks like this: 238 | 239 | [source,java] 240 | .stock-quotes/src/main/java/io/spring/workshop/stockquotes/StockQuotesApplication.java 241 | ---- 242 | include::../stock-quotes/src/main/java/io/spring/workshop/stockquotes/StockQuotesApplication.java[] 243 | ---- 244 | 245 | Edit your `application.properties` file to start the server on port 8081. 246 | 247 | [source,properties] 248 | .stock-quotes/src/main/resources/application.properties 249 | ---- 250 | include::../stock-quotes/src/main/resources/application.properties[] 251 | ---- 252 | 253 | Launching it from your IDE or with `mvn spring-boot:run` should start a Netty server on port 8081. 254 | You should see in the logs something like: 255 | 256 | [source,bash] 257 | ---- 258 | INFO 2208 --- [ restartedMain] o.s.b.web.embedded.netty.NettyWebServer : Netty started on port(s): 8081 259 | INFO 2208 --- [ restartedMain] i.s.w.s.StockQuotesApplication : Started StockQuotesApplication in 1.905 seconds (JVM running for 3.075) 260 | ---- 261 | 262 | === Create a Quote Generator 263 | 264 | To simulate real stock values, we'll create a generator that emits such values at a specific interval. 265 | Copy the following classes to your project. 266 | 267 | [source,java] 268 | .stock-quotes/src/main/java/io/spring/workshop/stockquotes/Quote.java 269 | ---- 270 | include::../stock-quotes/src/main/java/io/spring/workshop/stockquotes/Quote.java[] 271 | ---- 272 | 273 | [source,java] 274 | .stock-quotes/src/main/java/io/spring/workshop/stockquotes/QuoteGenerator.java 275 | ---- 276 | include::../stock-quotes/src/main/java/io/spring/workshop/stockquotes/QuoteGenerator.java[] 277 | ---- 278 | 279 | Because we're working with `java.time.Instant` and Jackson, we should import the dedicated module in our app. 280 | 281 | NOTE: The `QuoteGenerator` instantiates a `Flux` that emits a `Quote` every 200 msec and can be **shared** between 282 | multiple subscribers (look at the `Flux` operators for that). This instance is kept as an attribute for reusability. 283 | 284 | [source,xml] 285 | .stock-quotes/pom.xml 286 | ---- 287 | include::../stock-quotes/pom.xml[tags=jacksonJSR310] 288 | ---- 289 | 290 | === Functional web applications with "WebFlux.fn" 291 | 292 | Spring WebFlux comes in two flavors of web applications: annotation based and functional. 293 | For this first application, we'll use the functional variant. 294 | 295 | Incoming HTTP requests are handled by a `HandlerFunction`, which is essentially a function 296 | that takes a ServerRequest and returns a `Mono`. The annotation counterpart 297 | to a handler function would be a Controller method. 298 | 299 | But how those incoming requests are routed to the right handler? 300 | 301 | We're using a `RouterFunction`, which is a function that takes a `ServerRequest`, and returns 302 | a `Mono`. If a request matches a particular route, a handler function is returned; 303 | otherwise it returns an empty `Mono`. The `RouterFunction` has a similar purpose as the `@RequestMapping` 304 | annotation in `@Controller` classes. 305 | 306 | Take a look at the code samples in 307 | {spring-framework-doc-base}/spring-framework-reference/web.html#web-reactive-server-functional[the Spring WebFlux.fn reference documentation] 308 | 309 | === Create your first HandlerFunction + RouterFunction 310 | 311 | First, create a `QuoteHandler` class and mark is as a `@Component`;this class will have all our handler functions as methods. 312 | Let's inject our `QuoteGenerator` instance in our `QuoteHandler`. 313 | 314 | Now create a `streamQuotes` handler that streams the generated quotes with the `"application/stream+json"` content type. 315 | 316 | To route requests to that handler, you need to expose a `RouterFunction` to Spring Boot. 317 | Create a `QuoteRouter` configuration class (i.e. annotated with `@Configuration`) 318 | that creates a bean of type `RouterFunction`. 319 | 320 | Modify that class so that GET requests to `"/quotes"` are routed to the handler you just implemented. 321 | 322 | TIP: Since `QuoteHandler` is a component, you can inject it in `@Bean` methods as a method parameter. 323 | 324 | Your application should now behave like this: 325 | 326 | [source,bash] 327 | ---- 328 | $ curl http://localhost:8081/quotes -i -H "Accept: application/stream+json" 329 | HTTP/1.1 200 OK 330 | transfer-encoding: chunked 331 | Content-Type: application/stream+json 332 | 333 | {"ticker":"CTXS","price":84.0,"instant":1494841666.633000000} 334 | {"ticker":"DELL","price":67.1,"instant":1494841666.834000000} 335 | {"ticker":"GOOG","price":869,"instant":1494841667.034000000} 336 | {"ticker":"MSFT","price":66.5,"instant":1494841667.231000000} 337 | {"ticker":"ORCL","price":46.13,"instant":1494841667.433000000} 338 | {"ticker":"RHT","price":86.9,"instant":1494841667.634000000} 339 | {"ticker":"VMW","price":93.7,"instant":1494841667.833000000} 340 | ---- 341 | 342 | === Integration tests with WebTestClient 343 | 344 | Spring WebFlux (actually the `spring-test` module) includes a `WebTestClient` 345 | that can be used to test WebFlux server endpoints with or without a running server. 346 | Tests without a running server are comparable to MockMvc from Spring MVC where mock request 347 | and response are used instead of connecting over the network using a socket. 348 | The WebTestClient however can also perform tests against a running server. 349 | 350 | You can check that your last endpoint is working properly with the following 351 | integration test: 352 | 353 | [source,java] 354 | .stock-quotes/src/test/java/io/spring/workshop/stockquotes/StockQuotesApplicationTests.java 355 | ---- 356 | include::../stock-quotes/src/test/java/io/spring/workshop/stockquotes/StockQuotesApplicationTests.java[] 357 | ---- 358 | 359 | == Additional Resources 360 | 361 | Talks on Spring Reactive: 362 | 363 | * https://www.youtube.com/watch?v=rdgJ8fOxJhc[Reactive Web Applications with Spring 5 (Rossen Stoyanchev)] 364 | * https://www.youtube.com/watch?v=Cj4foJzPF80[Developing Reactive applications with Reactive Streams and Java 8 (B.Clozel, S.Deleuze)] 365 | -------------------------------------------------------------------------------- /docs/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | Spring WebFlux Workshop 10 | 11 | 420 | 421 | 422 | 423 | 457 |

This repository hosts a complete workshop on Spring Boot + Spring WebFlux. 462 | Just follow this README and create your first WebFlux applications! 463 | Each step of this workshop has its companion commit in the git history with a detailed commit message.

464 |
465 |
466 |

We’ll create two applications:

467 |
468 |
469 |
    470 |
  • 471 |

    stock-quotes is a functional WebFlux app which streams stock quotes

    472 |
    • 473 |
  • 474 |

    trading-service is an annotation-based WebFlux app using a datastore, HTML views, and several browser-related technologies

    475 |
    • 476 |
477 |
478 |
479 |

Reference documentations can be useful while working on those apps:

482 | 492 |
493 |
494 |
495 |
496 |

Stock Quotes application

497 |
498 |
499 |

Create this application

500 |
501 |

Go to https://start.spring.io and create a Maven project with Spring Boot 2.0.0.M1, 502 | with groupId io.spring.workshop and artifactId stock-quotes. Select the Reactive Web 503 | Boot starter. 504 | Unzip the given file into a directory and import that application into your IDE.

505 |
506 |
507 |

If generated right, you should have a main Application class that looks like this:

508 |
509 |
510 |
stock-quotes/src/main/java/io/spring/workshop/stockquotes/StockQuotesApplication.java
511 |
512 | 
package io.spring.workshop.stockquotes;
 513 | 
 514 | import org.springframework.boot.SpringApplication;
 515 | import org.springframework.boot.autoconfigure.SpringBootApplication;
 516 | 
 517 | @SpringBootApplication
 518 | public class StockQuotesApplication {
 519 | 
 520 | 	public static void main(String[] args) {
 521 | 		SpringApplication.run(StockQuotesApplication.class, args);
 522 | 	}
 523 | }
524 |
525 |
526 |
527 |

Edit your application.properties file to start the server on a specific port.

528 |
529 |
530 |
stock-quotes/src/main/resources/application.properties
531 |
532 | 
server.port=8081
533 |
534 |
535 |
536 |

Launching it from your IDE or with mvn spring-boot:run should start a Netty server on port 8081. 537 | You should see in the logs something like:

538 |
539 |

Create a Quote Generator

548 |
549 |

To simulate real stock values, we’ll create a generator that emits such values at a specific interval. 550 | Copy the following classes to your project.

551 |
552 |
553 |
stock-quotes/src/main/java/io/spring/workshop/stockquotes/Quote.java
554 |
555 | 
package io.spring.workshop.stockquotes;
 556 | 
 557 | import java.math.BigDecimal;
 558 | import java.math.MathContext;
 559 | import java.time.Instant;
 560 | 
 561 | public class Quote {
 562 | 
 563 | 	private static final MathContext MATH_CONTEXT = new MathContext(2);
 564 | 
 565 | 	private String ticker;
 566 | 
 567 | 	private BigDecimal price;
 568 | 
 569 | 	private Instant instant;
 570 | 
 571 | 	public Quote() {
 572 | 	}
 573 | 
 574 | 	public Quote(String ticker, BigDecimal price) {
 575 | 		this.ticker = ticker;
 576 | 		this.price = price;
 577 | 	}
 578 | 
 579 | 	public Quote(String ticker, Double price) {
 580 | 		this(ticker, new BigDecimal(price, MATH_CONTEXT));
 581 | 	}
 582 | 
 583 | 	public String getTicker() {
 584 | 		return ticker;
 585 | 	}
 586 | 
 587 | 	public void setTicker(String ticker) {
 588 | 		this.ticker = ticker;
 589 | 	}
 590 | 
 591 | 	public BigDecimal getPrice() {
 592 | 		return price;
 593 | 	}
 594 | 
 595 | 	public void setPrice(BigDecimal price) {
 596 | 		this.price = price;
 597 | 	}
 598 | 
 599 | 	public Instant getInstant() {
 600 | 		return instant;
 601 | 	}
 602 | 
 603 | 	public void setInstant(Instant instant) {
 604 | 		this.instant = instant;
 605 | 	}
 606 | 
 607 | 	@Override
 608 | 	public String toString() {
 609 | 		return "Quote{" +
 610 | 				"ticker='" + ticker + '\'' +
 611 | 				", price=" + price +
 612 | 				", instant=" + instant +
 613 | 				'}';
 614 | 	}
 615 | }
616 |

 673 | 				// Because values are generated in batches,

 677 | 					return quote;
 678 | 				})
 679 | 				.log("io.spring.workshop.stockquotes");
 680 | 	}

 683 | 		BigDecimal priceChange = quote.getPrice()
 684 | 				.multiply(new BigDecimal(0.05 * this.random.nextDouble()), this.mathContext);
 685 | 		return new Quote(quote.getTicker(), quote.getPrice().add(priceChange));
 686 | 	}
 687 | }
688 |
689 |
690 |
691 |

Because we’re working with java.time.Instant and Jackson, we should import the dedicated module in our app.

Functional web applications with "WebFlux.fn"

705 |
706 |

Spring WebFlux comes in two flavors of web applications: annotation based and functional. 707 | For this first application, we’ll use the functional variant.

708 |
709 |
710 |

Incoming HTTP requests are handled by a HandlerFunction, which is essentially a function 711 | that takes a ServerRequest and returns a Mono<ServerResponse>. The annotation counterpart 712 | to a handler function would be a Controller method.

713 |
714 |
715 |

But how those incoming requests are routed to the right handler?

716 |
717 |
718 |

We’re using a RouterFunction, which is a function that takes a ServerRequest, and returns 719 | a Mono<HandlerFunction>. If a request matches a particular route, a handler function is returned; 720 | otherwise it returns an empty Mono. The RouterFunction has a similar purpose as the @RequestMapping 721 | annotation in @Controller classes.

722 |
723 |
724 |

Take a look at the code samples in 725 | the Spring WebFlux.fn reference documentation

726 |
727 |
728 |
729 |

Create your first HandlerFunction + RouterFunction

730 |
731 |

First, create a QuoteHandler class and mark is as a @Component;this class will have all our handler functions as methods. 732 | Now create a hello handler function in that class that always returns "text/plain" HTTP responses with "Hello Spring!" as body.

733 |
734 |
735 |

To route requests to that handler, you need to expose a RouterFunction to Spring Boot. 736 | Create a QuoteRouter configuration class (i.e. annotated with @Configuration) 737 | that creates a bean of type RouterFunction<ServerResponse>.

738 |
739 |
740 |

Modify that class so that GET requests to "/hello" are routed to the handler you just implemented.

741 |
742 |
743 | 744 | 745 | 748 | 751 | 752 |
746 | 747 | 749 | Since QuoteHandler is a component, you can inject it in @Bean methods as a method parameter. 750 |
753 |
754 |
755 |

Your application should now behave like this:

756 |
757 |
758 |
759 | 
$ curl http://localhost:8081/hello -i
 760 | HTTP/1.1 200 OK
 761 | transfer-encoding: chunked
 762 | Content-Type: text/plain;charset=UTF-8
 763 | 
 764 | Hello Spring!%
765 |
766 |
767 |
768 |

Once done, add another endpoint:

769 |
770 |
771 |
    772 |
  • 773 |

    with a HandlerFunction echo that echoes the request body in the response, as "text/plain"

    774 |
    • 775 |
  • 776 |

    and an additional route in our existing RouterFunction that accepts POST requests on 777 | "/echo" with a "text/plain" body and returns responses with the same content type.

    778 |
    • 779 |
780 |
781 |
782 |

You can also use this new endpoint with:

783 |
784 |
785 |
786 | 
$ curl http://localhost:8081/echo -i -d "WebFlux workshop" -H "Content-Type: text/plain"
 787 | HTTP/1.1 200 OK
 788 | transfer-encoding: chunked
 789 | Content-Type: text/plain
 790 | 
 791 | WebFlux workshop%
792 |
793 |
794 |
795 |
796 |

Expose the Flux<Quotes> as a web service

797 |
798 |

First, let’s inject our QuoteGenerator instance in our QuoteHandler, instantiate 799 | a Flux<Quote> from it that emits a Quote every 200 msec and can be shared between 800 | multiple subscribers (look at the Flux operators for that). This instance should be kept 801 | as an attribute for reusability.

802 |
803 |
804 |

Now create a streamQuotes handler that streams those generated quotes 805 | with the "application/stream+json" content type. Add the corresponding part in the RouterFunction, 806 | on the "/quotes" endpoint.

807 |
808 |
809 |
810 | 
$ curl http://localhost:8081/quotes -i -H "Accept: application/stream+json"
 811 | HTTP/1.1 200 OK
 812 | transfer-encoding: chunked
 813 | Content-Type: application/stream+json
 814 | 
 815 | {"ticker":"CTXS","price":84.0,"instant":1494841666.633000000}
 816 | {"ticker":"DELL","price":67.1,"instant":1494841666.834000000}
 817 | {"ticker":"GOOG","price":869,"instant":1494841667.034000000}
 818 | {"ticker":"MSFT","price":66.5,"instant":1494841667.231000000}
 819 | {"ticker":"ORCL","price":46.13,"instant":1494841667.433000000}
 820 | {"ticker":"RHT","price":86.9,"instant":1494841667.634000000}
 821 | {"ticker":"VMW","price":93.7,"instant":1494841667.833000000}
822 |
823 |
824 |
825 |

Let’s now create a variant of that — instead of streaming all values (with an infinite stream), we can 826 | now take the last "n" elements of that Flux and return those as a collection of Quotes with 827 | the content type "application/json". Note that you should take the requested number of Quotes 828 | from the request itself, with the query parameter named "size" (or pick 10 as the default size 829 | if none was provided).

830 |
831 |
832 |
833 | 
curl http://localhost:8081/quotes -i -H "Accept: application/json"
 834 | HTTP/1.1 200 OK
 835 | transfer-encoding: chunked
 836 | Content-Type: application/json
 837 | 
 838 | [{"ticker":"CTXS","price":85.8,"instant":1494842241.716000000},{"ticker":"DELL","price":64.69,"instant":1494842241.913000000},{"ticker":"GOOG","price":856.5,"instant":1494842242.112000000},{"ticker":"MSFT","price":68.2,"instant":1494842242.317000000},{"ticker":"ORCL","price":47.4,"instant":1494842242.513000000},{"ticker":"RHT","price":85.6,"instant":1494842242.716000000},{"ticker":"VMW","price":96.1,"instant":1494842242.914000000},{"ticker":"CTXS","price":85.5,"instant":1494842243.116000000},{"ticker":"DELL","price":64.88,"instant":1494842243.316000000},{"ticker":"GOOG","price":889,"instant":1494842243.517000000}]%

Integration tests with WebTestClient

844 |
845 |

Spring WebFlux (actually the spring-test module) includes a WebTestClient 846 | that can be used to test WebFlux server endpoints with or without a running server. 847 | Tests without a running server are comparable to MockMvc from Spring MVC where mock request 848 | and response are used instead of connecting over the network using a socket. 849 | The WebTestClient however can also perform tests against a running server.

850 |
851 |
852 |

You can check that your last endpoint is working properly with the following 853 | integration test:

854 |
855 |

 873 | @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
 874 | public class StockQuotesApplicationTests {
 875 | 
 876 | 	// Spring Boot will create a `WebTestClient` for you,
 877 | 	// already configure and ready to issue requests against "localhost:RANDOM_PORT"
 878 | 	@Autowired
 879 | 	private WebTestClient webTestClient;
 880 | 
 881 | 	@Test
 882 | 	public void fetchQuotes() {
 883 | 		webTestClient
 884 | 				// We then create a GET request to test an endpoint
 885 | 				.get().uri("/quotes?size=20")

Trading Service application

906 |
907 |
908 |

Create this application

909 |
910 |

Go to https://start.spring.io and create a Maven project with Spring Boot 2.0.0.M1, 911 | with groupId io.spring.workshop and artifactId trading-service. Select the Reactive Web 912 | , Devtools, Thymeleaf and Reactive Mongo Boot starters. 913 | Unzip the given file into a directory and import that application into your IDE.

914 |
915 |
916 |
917 |

Use Tomcat as a web engine

918 |
919 |

By default, spring-boot-starter-webflux transitively brings spring-boot-starter-reactor-netty 920 | and Spring Boot auto-configures Reactor Netty as a web server. For this application, we’ll use 921 | Tomcat as an alternative.

922 |
923 |
924 |
trading-service/pom.xml
925 |
926 | 
		<dependency>
 927 | 			<groupId>org.springframework.boot</groupId>
 928 | 			<artifactId>spring-boot-starter-tomcat</artifactId>
 929 | 		</dependency>
930 |
931 |
932 |
933 |

Note that Spring Boot supports as well Undertow and Jetty.

934 |
935 |
936 |
937 |

Use a reactive datastore

938 |
939 |

In this application, we’ll use a MongoDB datastore with its reactive driver; 940 | for this workshop, we’ll use an in-memory instance of MongoDB. So add the following:

941 |
942 |
943 |
trading-service/pom.xml
944 |
945 | 
		<dependency>
 946 | 			<groupId>de.flapdoodle.embed</groupId>
 947 | 			<artifactId>de.flapdoodle.embed.mongo</artifactId>
 948 | 		</dependency>
949 |
950 |
951 |
952 |

We’d like to manage TradingUser with our datastore.

953 |
954 |
955 |
trading-service/src/main/java/io/spring/workshop/tradingservice/TradingUser.java
956 |
957 | 
package io.spring.workshop.tradingservice;
 958 | 
 959 | import org.springframework.data.annotation.Id;
 960 | import org.springframework.data.mongodb.core.mapping.Document;
 961 | 
 962 | @Document
 963 | public class TradingUser {
 964 | 
 965 | 	@Id
 966 | 	private String id;
 967 | 
 968 | 	private String userName;
 969 | 
 970 | 	private String fullName;
 971 | 
 972 | 	public TradingUser() {
 973 | 	}
 974 | 
 975 | 	public TradingUser(String id, String userName, String fullName) {
 976 | 		this.id = id;
 977 | 		this.userName = userName;
 978 | 		this.fullName = fullName;
 979 | 	}
 980 | 
 981 | 	public TradingUser(String userName, String fullName) {
 982 | 		this.userName = userName;
 983 | 		this.fullName = fullName;
 984 | 	}
 985 | 
 986 | 	public String getId() {
 987 | 		return id;
 988 | 	}
 989 | 
 990 | 	public void setId(String id) {
 991 | 		this.id = id;
 992 | 	}
 993 | 
 994 | 	public String getUserName() {
 995 | 		return userName;
 996 | 	}
 997 | 
 998 | 	public void setUserName(String userName) {
 999 | 		this.userName = userName;
1000 | 	}
1001 | 
1002 | 	public String getFullName() {
1003 | 		return fullName;
1004 | 	}
1005 | 
1006 | 	public void setFullName(String fullName) {
1007 | 		this.fullName = fullName;
1008 | 	}
1009 | 
1010 | 	@Override
1011 | 	public boolean equals(Object o) {
1012 | 		if (this == o) return true;
1013 | 		if (o == null || getClass() != o.getClass()) return false;
1014 | 
1015 | 		TradingUser that = (TradingUser) o;
1016 | 
1017 | 		if (!id.equals(that.id)) return false;
1018 | 		return userName.equals(that.userName);
1019 | 	}
1020 | 
1021 | 	@Override
1022 | 	public int hashCode() {
1023 | 		int result = id.hashCode();
1024 | 		result = 31 * result + userName.hashCode();
1025 | 		return result;
1026 | 	}
1027 | }
1028 |
1029 |
1030 |
1031 |

Now create a TradingUserRepository interface that extends ReactiveMongoRepository. 1032 | Add a findByUserName(String userName) method that returns a single TradingUser in a reactive fashion.

1033 |
1034 |
1035 |

We’d like to insert users in our datastore when the application starts up. For that, create a UsersCommandLineRunner 1036 | component that implements Spring Boot’s CommandLineRunner. In the run method, use the reactive repository 1037 | to insert TradingUser instances in the datastore.

1038 |
1039 |
1040 | 1041 | 1042 | 1045 | 1050 | 1051 |
1043 | 1044 | 1046 | Since the run method returns void, it expects a blocking implementation. This is why you should use the 1047 | blockLast(Duration) operator on the Flux returned by the repository when inserting data. 1048 | You can also then().block(Duration) to turn that Flux into a Mono<Void> that waits for completion. 1049 |
1052 |
1053 |
1054 |
1055 |

Create a JSON web service

1056 |
1057 |

We’re now going to expose TradingUser through a Controller. 1058 | First, create a UserController annotated with @RestController. 1059 | Then add two new Controller methods in order to handle:

1060 |
1061 |
1062 |
    1063 |
  • 1064 |

    GET requests to "/users", returning all TradingUser instances, serializing them with content-type "application/json"

    1065 |
    • 1066 |
  • 1067 |

    GET requests to "/users/{username}", returning a single TradingUser instance, serializing it with content-type "application/json"

    1068 |
    • 1069 |
1070 |
1071 |
1072 |

You can now validate your implementation with the following test:

1073 |
1074 |
1075 |

Use Thymeleaf to render HTML views

1137 |
1138 |

We already added the Thymeleaf Boot starter when we created our trading application.

1139 |
1140 |
1141 |

First, let’s add a couple of WebJar dependencies to get static resources for our application:

1142 |
1143 |
1144 |
trading-service/pom.xml
1145 |
1146 | 
		<dependency>
1147 | 			<groupId>org.webjars</groupId>
1148 | 			<artifactId>bootstrap</artifactId>
1149 | 			<version>3.3.7</version>
1150 | 		</dependency>
1151 | 		<dependency>
1152 | 			<groupId>org.webjars</groupId>
1153 | 			<artifactId>highcharts</artifactId>
1154 | 			<version>5.0.8</version>
1155 | 		</dependency>
1156 |
1157 |
1158 |
1159 |

We can now create HTML templates in our src/main/resources/templates folder and map them using controllers.

1160 |
1161 |
1162 |
trading-service/src/main/resources/templates/index.html

1205 |             <td th:text="${user.fullName}">Jane Doe</td>
1206 |         </tr>
1207 |         </tbody>
1208 |     </table>
1209 | </div>
1210 | <script type="text/javascript" src="/webjars/jquery/1.11.1/jquery.min.js"></script>

1212 | </body>
1213 | </html>
1214 |
1215 |
1216 |
1217 |

As you can see in that template, we loop over the "users" attribute and write a row in our HTML table for each.

1218 |
1219 |
1220 |

Let’s display those users in our application:

1221 |
1222 |
1223 |
    1224 |
  • 1225 |

    Create a HomeController Controller

    1226 |
    • 1227 |
  • 1228 |

    Add a Controller method that handles GET requests to "/"

    1229 |
    • 1230 |
  • 1231 |

    Inject the Spring Model on that method and add a "users" attribute to it

    1232 |
    • 1233 |
1234 |
1235 |
1236 | 1237 | 1238 | 1241 | 1245 | 1246 |
1239 | 1240 | 1242 | Spring WebFlux will resolve automatically Publisher instances before rendering the view, 1243 | there’s no need to involve blocking code at all! 1244 |
1247 |
1248 |
1249 |
1250 |

Use the WebClient to stream JSON to the browser

1251 |
1252 |

In this section, we’ll call our remote stock-quotes service to get Quotes from it, so we first need to:

1253 |
1254 |
1255 |
    1256 |
  • 1257 |

    copy over the Quote class to this application

    1258 |
    • 1259 |
  • 1260 |

    add the Jackson JSR310 module dependency

    1261 |
    • 1262 |
1263 |
1264 |
1265 |

Add the following template file to your application:

1327 |         }, {
1328 |             name: 'MSFT',

1331 |             name: 'ORCL',
1332 |             data: []
1333 |         }, {
1334 |             name: 'RHT',
1335 |             data: []
1336 |         }, {
1337 |             name: 'VMW',
1338 |             data: []
1339 |         }, {
1340 |             name: 'DELL',
1341 |             data: []
1342 |         }]
1343 |     });
1344 | 
1345 |     // This function adds the given data point to the chart
1346 |     var appendStockData = function (quote) {
1347 |         chart.series
1348 |             .filter(function (serie) {
1349 |                 return serie.name == quote.ticker
1350 |             })
1351 |             .forEach(function (serie) {
1352 |                 var shift = serie.data.length > 40;
1353 |                 serie.addPoint([quote.instant * 1000, quote.price], true, shift);
1354 |             });
1355 |     };
1356 | 
1357 |     // The browser connects to the server and receives quotes using ServerSentEvents
1358 |     // those quotes are appended to the chart as they're received
1359 |     var stockEventSource = new EventSource("/quotes/feed");
1360 |     stockEventSource.onmessage = function (e) {
1361 |         appendStockData(JSON.parse(e.data));
1362 |     };
1363 | </script>
1364 | </body>
1365 | </html>
1366 |
1367 |
1368 |
1369 |

As you can see in this template file, loading that HTML page will cause the browser to send a request 1370 | the server for Quotes using the Server Sent Event transport.

1371 |
1372 |
1373 |

Now create a QuotesController annotated with @Controller and add two methods. 1374 | One that renders the quotes.html template for incoming "GET /quotes" requests. 1375 | The other should response to "GET /quotes/feed" requests with the "text/event-stream" content-type, 1376 | with a Flux<Quote> as the response body. This data is already server by the stock-quotes application 1377 | , so you can use a WebClient to request the remote web service to retrieve that Flux.

1378 |
1379 |
1380 | 1381 | 1382 | 1385 | 1389 | 1390 |
1383 | 1384 | 1386 | You should avoid making a request to the stock-quotes service for every browser connecting to 1387 | that page — for that, you can use the Flux.share() operator. 1388 |
1391 |
1392 |
1393 |
1394 |

Create and Configure a WebSocketHandler

1395 |
1396 |

WebFlux includes functional reactive WebSocket client and server support.

1397 |
1398 |
1399 |

On the server side there are two main components: WebSocketHandlerAdapter will handle the incoming 1400 | requests by delegating to the configured WebSocketService and WebSocketHandler will be responsible 1401 | to handle WebSocket session.

1402 |
1403 |
1404 |

Take a look at the code samples in 1405 | Reactive WebSocket Support documentation

1406 |
1407 |
1408 |

First, create an EchoWebSocketHandler class; it has to implement WebSocketHandler. 1409 | Now implement handle(WebSocketSession session) method. The handler echoes the incoming messages with a delay of 1s.

1410 |
1411 |
1412 |

To route requests to that handler, you need to map the above WebSocket handler to a specific URL: here, "/websocket/echo". 1413 | Create a WebSocketRouter configuration class (i.e. annotated with @Configuration) that creates a bean of type HandlerMapping. 1414 | Create one additional bean of type WebSocketHandlerAdapter which will delegate the processing of 1415 | the incoming request to the default WebSocketService which is HandshakeWebSocketService.

1416 |
1417 |
1418 |

Now create a WebSocketController annotated with @Controller and add a method that renders the 1419 | websocket.html template for incoming "GET /websocket" requests.

1420 |
1421 |
1422 |

Add the following template file to your application:

1423 |
1424 |

Integration tests with WebSocketClient

1500 |
1501 |

WebSocketClient included in Spring WebFlux can be used to test your WebSocket endpoints.

1502 |
1503 |
1504 |

You can check that your WebSocket endpoint, created in the previous section, is working properly with the 1505 | following integration test:
