For Maven, you need a `pom.xml` with `` 28 | that list the subdirectories: 29 | 30 | ==== 31 | [src,xml] 32 | ---- 33 | include::complete/pom.xml[] 34 | ---- 35 | ==== 36 | 37 | For Gradle, you need want a `settings.gradle` that includes the same directories: 38 | 39 | ==== 40 | [src,groovy] 41 | ---- 42 | include::complete/settings.gradle[] 43 | ---- 44 | ==== 45 | 46 | Optionally, you can include an empty `build.gradle` (to help IDEs identify the root directory). 47 | 48 | 49 | === Create the Directory Structure 50 | 51 | In the directory that you want to be your root directory, create the following 52 | subdirectory structure (for example, with `mkdir say-hello user` on *nix systems): 53 | 54 | └── say-hello 55 | └── user 56 | 57 | In the root of the project, you need to set up a build system, and this guide shows 58 | you how to use Maven or Gradle. 59 | 60 | [[initial]] 61 | == Starting with Spring Initializr 62 | 63 | If you use Maven for the `Say Hello` project, visit the https://start.spring.io/#!type=maven-project&language=java&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=spring-cloud-loadbalancer-say-hello&name=spring-cloud-loadbalancer-say-hello&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.spring-cloud-loadbalancer-say-hello&dependencies=web[Spring Initializr] to generate a new project with the required dependency (Spring Web). 64 | 65 | The following listing shows the `pom.xml` file that is created when you choose Maven: 66 | 67 | ==== 68 | [source,xml] 69 | ---- 70 | include::initial/say-hello/pom.xml[] 71 | ---- 72 | ==== 73 | 74 | If you use Gradle for the `Say Hello` project, visit the https://start.spring.io/#!type=gradle-project&language=java&&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=spring-cloud-loadbalancer-say-hello&name=spring-cloud-loadbalancer-say-hello&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.spring-cloud-loadbalancer-say-hello&dependencies=web[Spring Initializr] to generate a new project with the required dependency (Spring Web). 75 | 76 | The following listing shows the `build.gradle` file that is created when you choose Gradle: 77 | 78 | ==== 79 | [source,text] 80 | ---- 81 | include::initial/say-hello/build.gradle[] 82 | ---- 83 | ==== 84 | 85 | If you use Maven for the `User` project, visit the https://start.spring.io/#!type=maven-project&language=java&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=spring-cloud-loadbalancer-user&name=spring-cloud-loadbalancer-user&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.spring-cloud-loadbalancer-user&dependencies=cloud-loadbalancer,webflux[Spring Initializr] to generate a new project with the required dependencies (Cloud Loadbalancer and Spring Reactive Web). 86 | 87 | The following listing shows the `pom.xml` file that is created when you choose Maven: 88 | 89 | ==== 90 | [source,xml] 91 | ---- 92 | include::initial/user/pom.xml[] 93 | ---- 94 | ==== 95 | 96 | If you use Gradle for the `User` project, visit the https://start.spring.io/#!type=gradle-project&language=java&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=spring-cloud-loadbalancer-user&name=spring-cloud-loadbalancer-user&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.spring-cloud-loadbalancer-user&dependencies=cloud-loadbalancer,webflux[Spring Initializr] to generate a new project with the required dependencies (Cloud Loadbalancer and Spring Reactive Web). 97 | 98 | The following listing shows the `build.gradle` file that is created when you choose Gradle: 99 | 100 | ==== 101 | [source,text] 102 | ---- 103 | include::initial/user/build.gradle[] 104 | ---- 105 | ==== 106 | 107 | === Manual Initialization (optional) 108 | 109 | If you want to initialize the project manually rather than use the links shown earlier, follow the steps given below: 110 | 111 | . Navigate to https://start.spring.io. 112 | This service pulls in all the dependencies you need for an application and does most of the setup for you. 113 | . Choose either Gradle or Maven and the language you want to use. This guide assumes that you chose Java. 114 | . Click *Dependencies* and select *Spring Web* (for the `Say Hello` project) or *Cloud Loadbalancer* and *Spring Reactive Web* (for the `User` project). 115 | . Click *Generate*. 116 | . Download the resulting ZIP file, which is an archive of a web application that is configured with your choices. 117 | 118 | NOTE: If your IDE has the Spring Initializr integration, you can complete this process from your IDE. 119 | 120 | == Implement the "Say Hello" service 121 | 122 | Our "`server`" service is called `Say Hello`. 123 | It returns a random greeting (picked out of a static list of three) from an endpoint that is accessible at `/greeting`. 124 | 125 | In `src/main/java/hello`, create the file `SayHelloApplication.java`. 126 | 127 | The following listing shows the contents of `say-hello/src/main/java/hello/SayHelloApplication.java`: 128 | 129 | ==== 130 | [source,java,tabsize=2] 131 | ---- 132 | include::complete/say-hello/src/main/java/hello/SayHelloApplication.java[] 133 | ---- 134 | ==== 135 | 136 | It is a simple `@RestController`, where we have one `@RequestMapping method` for the `/greeting` and another for the root path `/`. 137 | 138 | We are going to run multiple instances of this application locally alongside a client service application. 139 | To get started: 140 | 141 | . Create a `src/main/resources` directory. 142 | . Create a `application.yml` file within the directory. 143 | . In that file, set a default value for `server.port`. 144 | 145 | (We will instruct the other instances of the application to run on other ports so that none of the `Say Hello` instances conflict with the client when we get that running). 146 | While we are in this file, we can set the `spring.application.name` for our service too. 147 | 148 | The following listing shows the contents of `say-hello/src/main/resources/application.yml`: 149 | 150 | ==== 151 | [source,java,tabsize=2] 152 | ---- 153 | include::complete/say-hello/src/main/resources/application.yml[] 154 | ---- 155 | ==== 156 | 157 | == Access from a Client Service 158 | 159 | Our users see the `User` application. 160 | It makes a call to the `Say Hello` application to get a greeting and then sends that greeting to our user when the user visits the endpoints at `/hi` and `/hello`. 161 | 162 | In the User application directory, under `src/main/java/hello`, add the `UserApplication.java` file: 163 | 164 | The following listing shows the contents of `user/src/main/java/hello/UserApplication.java` 165 | 166 | ==== 167 | [source,java,tabsize=2] 168 | ---- 169 | include::complete/user/src/main/java/hello/UserApplication.java[] 170 | ---- 171 | ==== 172 | We also need a `@Configuration` class where we set up a load-balanced `WebClient.Builder` instance: 173 | 174 | The following listing shows the contents of `user/src/main/java/hello/WebClientConfig.java`: 175 | 176 | ==== 177 | [source,java,tabsize=2] 178 | ---- 179 | include::complete/user/src/main/java/hello/WebClientConfig.java[] 180 | ---- 181 | ==== 182 | 183 | The configuration provides a `@LoadBalanced WebClient.Builder` instance, which we use when someone hits the `hi` endpoint of 184 | `UserApplication.java`. 185 | Once the `hi` endpoint is hit, we use this builder to create a `WebClient` instance, which makes an HTTP `GET` request to the `Say Hello` service's URL and gives us the result as a `String`. 186 | 187 | In `UserApplication.java`, we have also added a `/hello` endpoint that does the same action. However, rather than use the `@LoadBalanced` annotation, we use an `@Autowired` load-balancer exchange filter function (`lbFunction`), which we pass by using the `filter()` method to a `WebClient` instance that we programmatically build. 188 | 189 | TIP: Even though we set up the load-balanced `WebClient` instance slightly differently for the two endpoints, the end behavior for both is exactly the same. 190 | Spring Cloud LoadBalancer is used to select an appropriate instance of the `Say Hello` service. 191 | 192 | Add the `spring.application.name` and `server.port` properties to `src/main/resources/application.properties` or `src/main/resources/application.yml`: 193 | 194 | The following listing shows the contents of `user/src/main/resources/application.yml` 195 | 196 | ==== 197 | [source,yaml] 198 | ---- 199 | include::complete/user/src/main/resources/application.yml[] 200 | ---- 201 | ==== 202 | 203 | == Loadbalance Across Server Instances 204 | 205 | Now we can access `/hi` or `hello` on the User service and see a friendly greeting: 206 | 207 | ==== 208 | [source,bash] 209 | ---- 210 | $ curl http://localhost:8888/hi 211 | Greetings, Mary! 212 | 213 | $ curl http://localhost:8888/hi?name=Orontes 214 | Salutations, Orontes! 215 | ---- 216 | ==== 217 | 218 | In `WebClientConfig.java`, we pass a custom configuration for the LoadBalancer by using the `@LoadBalancerClient` annotation: 219 | 220 | ==== 221 | [source,java] 222 | ---- 223 | @LoadBalancerClient(name = "say-hello", configuration = SayHelloConfiguration.class) 224 | ---- 225 | ==== 226 | 227 | This means that, whenever a service named `say-hello` is contacted, instead of running with the default setup, Spring Cloud LoadBalancer uses the configuration provided in `SayHelloConfiguration.java`. 228 | 229 | The following listing shows the contents of `user/src/main/java/hello/SayHelloConfiguration.java`: 230 | 231 | ==== 232 | [source,java,tabsize=2] 233 | ---- 234 | include::complete/user/src/main/java/hello/SayHelloConfiguration.java[] 235 | ---- 236 | ==== 237 | 238 | In that class, we provide a custom `ServiceInstanceListSupplier` with three hard-coded instances that Spring Cloud LoadBalancer chooses from while making the calls to the `Say Hello` service. 239 | 240 | NOTE: This step has been added to explain how you can pass your own custom configuration to the Spring Cloud LoadBalancer. 241 | However, you need not use the `@LoadBalancerClient` annotation and create your own configuration for the LoadBalancer. 242 | The most typical way is to use Spring Cloud LoadBalancer with service discovery. 243 | If you have any `DiscoveryClient` on your classpath, the default Spring Cloud LoadBalancer configuration uses it to check for service instances. As a result, you only choose from instances that are up and running. 244 | You can learn how to use `ServiceDiscovery` with this https://spring.io/guides/gs/service-registration-and-discovery/[guide]. 245 | 246 | We also add an `application.yml` file with default `server.port` and `spring.application.name`. 247 | 248 | The following listing shows the contents of `user/src/main/resources/application.yml`: 249 | 250 | ==== 251 | [source,yaml] 252 | ---- 253 | include::complete/user/src/main/resources/application.yml[] 254 | ---- 255 | ==== 256 | 257 | == Testing the Loadbalancer 258 | 259 | The following listing shows how to run the `Say Hello` service with Gradle: 260 | 261 | ==== 262 | [source,bash] 263 | ---- 264 | $ ./gradlew bootRun 265 | ---- 266 | ==== 267 | 268 | The following listing shows how to run the `Say Hello` service with Maven: 269 | 270 | ==== 271 | [source,bash] 272 | ---- 273 | $ mvn spring-boot:run 274 | ---- 275 | ==== 276 | 277 | To achieve load balancing, you need two servers running separate instances of the same application. 278 | You can achieve that by running a second instance of the `Say Hello` service on a different port. 279 | We use port 9999 for this example. 280 | 281 | To do so with Gradle, open a new terminal and run the following command: 282 | 283 | ==== 284 | [source,bash] 285 | ---- 286 | export SERVER_PORT=9092 287 | ./gradlew bootRun 288 | ---- 289 | ==== 290 | 291 | To do so with Maven, open a new terminal and run the following commands: 292 | 293 | ==== 294 | [source,bash] 295 | ---- 296 | export SERVER_PORT=9999 297 | mvn spring-boot:run 298 | ---- 299 | ==== 300 | 301 | Then you can start the `User` service. At this point, you should have three terminals: two for two instances of `Say Hello` and one for `User`. 302 | Then you can access `localhost:8888/hi` and watch the `Say Hello` service instances. 303 | 304 | Your requests to the `User` service should result in calls to `Say Hello` being spread across the running instances in round-robin fashion: 305 | 306 | ==== 307 | ---- 308 | 2016-03-09 21:15:28.915 INFO 90046 --- [nio-8090-exec-7] hello.SayHelloApplication : Access /greeting 309 | ---- 310 | ==== 311 | 312 | == Summary 313 | 314 | Congratulations!
