| ## What You Will Learn during this Step: 2 | - Set up an Maven Project with Eclipse. 3 | - Intellij Link : https://www.jetbrains.com/help/idea/2016.2/getting-started-with-maven.html#create_maven_project 4 | - Copy Two Files pom.xml and Application.java 5 | - Launch Your First Spring Boot Application. 6 | - You will be introduced to Maven 7 | - Dependency Management 8 | 9 | ## Cool thing to note! 10 | - Without a lot of configuration, we are up and running with a web application 11 | - Refer https://github.com/in28minutes/SpringMvcStepByStep/blob/master/Step15.md to understand the sort of stuff - web.xml, dispatcher servlet configuration, maven dependency management and plugins - that are need to launch a typical web application without Spring Boot! 12 | 13 | ## What You Will NOT Learn during this Step: 14 | - Spring Boot does a lot of magic. This magic is called Auto Configuration. We will discuss about different terms related to Spring Boot - Starter Parent, Starter projects, Auto configuration - in depth during our first 10 steps. 15 | - As far as this step is concerned, we will focus on getting up and running with Spring Boot. We will understand all the magic a little later. 16 | - We will copy a lot of code in this step - just to avoid typos 17 | 18 | ## Exercises 19 | - If you are comfortable with Spring, try to create a few dependencies and see if are automatically auto-wired! 20 | 21 | ## Files List 22 | ### pom.xml 23 | ``` 24 | 26 | 4.0.0 27 | com.in28minutes.springboot 28 | first-springboot-project 29 | 0.0.1-SNAPSHOT 30 | 31 | org.springframework.boot 32 | spring-boot-starter-parent 33 | 1.4.0.RELEASE 34 | 35 | 36 | 37 | 1.8 38 | 39 | 40 | 41 | 42 | org.springframework.boot 43 | spring-boot-starter-web 44 | 45 | 46 | 47 | 48 | 49 | 50 | org.springframework.boot 51 | spring-boot-maven-plugin 52 | 53 | 54 | 55 | 56 | ``` 57 | ### src/main/java/com/in28minutes/springboot/Application.java 58 | ``` 59 | package com.in28minutes.springboot; 60 | 61 | import org.springframework.boot.SpringApplication; 62 | import org.springframework.boot.autoconfigure.SpringBootApplication; 63 | import org.springframework.context.ApplicationContext; 64 | 65 | @SpringBootApplication 66 | public class Application { 67 | 68 | public static void main(String[] args) { 69 | ApplicationContext ctx = SpringApplication.run(Application.class, args); 70 | 71 | } 72 | 73 | } 74 | ``` 75 | -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step01.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/05.Spring-Boot-Advanced/Step01.zip -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step02.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Lets add a RestController with a dependency and see Spring Boot Magic live 3 | 4 | ## Theory Break : Quick Spring and Spring MVC Primer 5 | - What is dependency?

As a Spring Boot developer, you need to understand what's happening beneath the hood of Spring Boot! 3 | - spring-boot-starter-web : starter for building applications with Spring MVC. Tomcat is default embedded container. 4 | - We already added this starter in the first step! Now we will explore the features it provides 5 | - We will enable logging in DEBUG mode to understand further 6 | 7 | ##spring-boot-starter-web 8 | - Spring Boot Starter Web brings all dependencies needed to build normal and RESTful web applications. Look at the dependency tree. 9 | - All the dependencies are added in because of spring-boot-starter-web 10 | - Also look at /META-INF/spring.provides inside the spring-boot-starter-web.jar 11 | - Spring Boot Starter Web auto configures things needed to startup a web application. Look at the log 12 | - Mapping servlet: 'dispatcherServlet' to [/] 13 | - Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest) 14 | - Mapped URL path [/webjars/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 15 | - Look at package org.springframework.boot.autoconfigure.web in spring-boot-autoconfigure-*.jar 16 | - Go to url http://localhost:8080/some-non-existing-url 17 | 18 | ## Useful Snippets 19 | /src/main/resources/application.properties 20 | ``` 21 | logging.level.org.springframework: DEBUG 22 | ``` 23 | 24 | ## Files List 25 | ### pom.xml 26 | ``` 27 | 29 | 4.0.0 30 | com.in28minutes.springboot 31 | first-springboot-project 32 | 0.0.1-SNAPSHOT 33 | 34 | org.springframework.boot 35 | spring-boot-starter-parent 36 | 1.4.0.RELEASE 37 | 38 | 39 | 40 | 1.8 41 | 42 | 43 | 44 | 45 | org.springframework.boot 46 | spring-boot-starter-web 47 | 48 | 49 | 50 | 51 | 52 | 53 | org.springframework.boot 54 | spring-boot-maven-plugin 55 | 56 | 57 | 58 | 59 | ``` 60 | ### src/main/java/com/in28minutes/springboot/Application.java 61 | ``` 62 | package com.in28minutes.springboot; 63 | 64 | import org.springframework.boot.SpringApplication; 65 | import org.springframework.boot.autoconfigure.SpringBootApplication; 66 | import org.springframework.context.ApplicationContext; 67 | 68 | @SpringBootApplication 69 | public class Application { 70 | 71 | public static void main(String[] args) { 72 | ApplicationContext ctx = SpringApplication.run(Application.class, args); 73 | 74 | } 75 | 76 | } 77 | ``` 78 | ### src/main/java/com/in28minutes/springboot/WelcomeController.java 79 | ``` 80 | package com.in28minutes.springboot; 81 | 82 | import org.springframework.beans.factory.annotation.Autowired; 83 | import org.springframework.web.bind.annotation.RequestMapping; 84 | import org.springframework.web.bind.annotation.RestController; 85 | 86 | @RestController 87 | public class WelcomeController { 88 | 89 | //Auto wiring 90 | @Autowired 91 | private WelcomeService service; 92 | 93 | @RequestMapping("/welcome") 94 | public String welcome() { 95 | return service.retrieveWelcomeMessage(); 96 | } 97 | } 98 | ``` 99 | ### src/main/java/com/in28minutes/springboot/WelcomeService.java 100 | ``` 101 | package com.in28minutes.springboot; 102 | 103 | import org.springframework.stereotype.Component; 104 | 105 | @Component 106 | public class WelcomeService { 107 | 108 | public String retrieveWelcomeMessage() { 109 | //Complex Method 110 | return "Good Morning updated"; 111 | } 112 | } 113 | ``` 114 | ### src/main/resources/application.properties 115 | ``` 116 | logging.level.org.springframework: DEBUG 117 | ``` 118 | -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step04.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Understand Starter Parent 3 | - How to override things defined in Starter Parent 4 | - Other starter projects 5 | 6 | ## Starter Parent 7 | - Dependency Versions 8 | - Java Versions 9 | - Default Plugins 10 | 11 | ## Other Starter Projects 12 | - spring-boot-starter-web-services 13 | - spring-boot-starter-test 14 | - spring-boot-starter-jdbc 15 | - spring-boot-starter-security 16 | - spring-boot-starter-data-jpa 17 | - spring-boot-starter-data-rest 18 | - More at https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#using-boot-starter 19 | 20 | ## Useful Snippets and References 21 | First Snippet 22 | ``` 23 | 24 | org.springframework.boot 25 | spring-boot-starter-parent 26 | 1.4.0.RELEASE 27 | 28 | ``` 29 | -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step05.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Spring Boot vs Spring 3 | - What Spring Boot is Not! 4 | 5 | ## Spring Boot vs Spring 6 | 7 | ### Spring 8 | - Spring is just a dependency injection framework. Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments. 9 | - First half of the 2000 decade! EJBs 10 | - EJBs were NOT easy to develop. 11 | - Write a lot of xml and plumbing code to get EJBs running 12 | - Impossible to Unit Test 13 | - Alternative - Writing simple JDBC Code involved a lot of plumbing 14 | - Spring framework started with aim of making Java EE development simpler. 15 | - Goals 16 | - Make applications testable. i.e. easier to write unit tests 17 | - Reduce plumbing code of JDBC and JMS 18 | - Simple architecture. Minus EJB. 19 | - Integrates well with other popular frameworks. 20 | 21 | ### Applications with Spring Framework 22 | - Over the next few years, a number of applications were developed with Spring Framework 23 | - Testable but 24 | - Lot of configuration (XML and Java) 25 | - Developing Spring Based application need configuration of a lot of beans! 26 | - Integration with other frameworks need configuration as well! 27 | - In the last few years, focus is moving from monolith applications to microservices. We need to be able to start project quickly. Minimum or Zero start up time 28 | - Framework Setup 29 | - Deployment - Configurability 30 | - Logging, Transaction Management 31 | - Monitoring 32 | - Web Server Configuration 33 | 34 | ### Spring Boot 35 | - Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”. 36 | - We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. 37 | - Example Problem Statements 38 | - You want to add Hibernate to your project. You dont worry about configuring a data source and a session factory. I will do if for you! 39 | - Goals 40 | - Provide quick start for projects with Spring. 41 | - Be opinionated but provide options. 42 | - Provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration). 43 | 44 | #### What Spring Boot is NOT? 45 | - It’s not an app or a web server 46 | - Does not implement any specific framework - for example, JPA or JMS 47 | - Does not generate code 48 | 49 | -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step06.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/05.Spring-Boot-Advanced/Step06.zip -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step08.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/05.Spring-Boot-Advanced/Step08.zip -------------------------------------------------------------------------------- /05.Spring-Boot-Advanced/Step09.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - I hate the fact that I've to stop and start the server each time.

during this Step: 2 | - Set up an Maven Project with Eclipse. 3 | - Intellij Link : https://www.jetbrains.com/help/idea/2016.2/getting-started-with-maven.html#create_maven_project 4 | - Copy Two Files pom.xml and Application.java 5 | - Launch Your First Spring Boot Application. 6 | - You will be introduced to Maven 7 | - Dependency Management 8 | 9 | ## Cool thing to note! 10 | - Without a lot of configuration, we are up and running with a web application 11 | - Refer https://github.com/in28minutes/SpringMvcStepByStep/blob/master/Step15.md to understand the sort of stuff - web.xml, dispatcher servlet configuration, maven dependency management and plugins - that are need to launch a typical web application without Spring Boot! 12 | 13 | ## What You Will NOT Learn during this Step: 14 | - Spring Boot does a lot of magic. This magic is called Auto Configuration. We will discuss about different terms related to Spring Boot - Starter Parent, Starter projects, Auto configuration - in depth during our first 10 steps. 15 | - As far as this step is concerned, we will focus on getting up and running with Spring Boot. We will understand all the magic a little later. 16 | - We will copy a lot of code in this step - just to avoid typos 17 | 18 | ## Exercises 19 | - If you are comfortable with Spring, try to create a few dependencies and see if are automatically auto-wired! 20 | 21 | ## Files List 22 | ### pom.xml 23 | ``` 24 | 26 | 4.0.0 27 | com.in28minutes.springboot 28 | first-springboot-project 29 | 0.0.1-SNAPSHOT 30 | 31 | org.springframework.boot 32 | spring-boot-starter-parent 33 | 1.4.0.RELEASE 34 | 35 | 36 | 37 | 1.8 38 | 39 | 40 | 41 | 42 | org.springframework.boot 43 | spring-boot-starter-web 44 | 45 | 46 | 47 | 48 | 49 | 50 | org.springframework.boot 51 | spring-boot-maven-plugin 52 | 53 | 54 | 55 | 56 | ``` 57 | ### src/main/java/com/in28minutes/springboot/Application.java 58 | ``` 59 | package com.in28minutes.springboot; 60 | 61 | import org.springframework.boot.SpringApplication; 62 | import org.springframework.boot.autoconfigure.SpringBootApplication; 63 | import org.springframework.context.ApplicationContext; 64 | 65 | @SpringBootApplication 66 | public class Application { 67 | 68 | public static void main(String[] args) { 69 | ApplicationContext ctx = SpringApplication.run(Application.class, args); 70 | 71 | } 72 | 73 | } 74 | ``` 75 | -------------------------------------------------------------------------------- /Step01.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/Step01.zip -------------------------------------------------------------------------------- /Step02.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Lets add a RestController with a dependency and see Spring Boot Magic live 3 | 4 | ## Theory Break : Quick Spring and Spring MVC Primer 5 | - What is dependency?

As a Spring Boot developer, you need to understand what's happening beneath the hood of Spring Boot! 3 | - spring-boot-starter-web : starter for building applications with Spring MVC. Tomcat is default embedded container. 4 | - We already added this starter in the first step! Now we will explore the features it provides 5 | - We will enable logging in DEBUG mode to understand further 6 | 7 | ##spring-boot-starter-web 8 | - Spring Boot Starter Web brings all dependencies needed to build normal and RESTful web applications. Look at the dependency tree. 9 | - All the dependencies are added in because of spring-boot-starter-web 10 | - Also look at /META-INF/spring.provides inside the spring-boot-starter-web.jar 11 | - Spring Boot Starter Web auto configures things needed to startup a web application. Look at the log 12 | - Mapping servlet: 'dispatcherServlet' to [/] 13 | - Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest) 14 | - Mapped URL path [/webjars/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 15 | - Look at package org.springframework.boot.autoconfigure.web in spring-boot-autoconfigure-*.jar 16 | - Go to url http://localhost:8080/some-non-existing-url 17 | 18 | ## Useful Snippets 19 | /src/main/resources/application.properties 20 | ``` 21 | logging.level.org.springframework: DEBUG 22 | ``` 23 | 24 | ## Files List 25 | ### pom.xml 26 | ``` 27 | 29 | 4.0.0 30 | com.in28minutes.springboot 31 | first-springboot-project 32 | 0.0.1-SNAPSHOT 33 | 34 | org.springframework.boot 35 | spring-boot-starter-parent 36 | 1.4.0.RELEASE 37 | 38 | 39 | 40 | 1.8 41 | 42 | 43 | 44 | 45 | org.springframework.boot 46 | spring-boot-starter-web 47 | 48 | 49 | 50 | 51 | 52 | 53 | org.springframework.boot 54 | spring-boot-maven-plugin 55 | 56 | 57 | 58 | 59 | ``` 60 | ### src/main/java/com/in28minutes/springboot/Application.java 61 | ``` 62 | package com.in28minutes.springboot; 63 | 64 | import org.springframework.boot.SpringApplication; 65 | import org.springframework.boot.autoconfigure.SpringBootApplication; 66 | import org.springframework.context.ApplicationContext; 67 | 68 | @SpringBootApplication 69 | public class Application { 70 | 71 | public static void main(String[] args) { 72 | ApplicationContext ctx = SpringApplication.run(Application.class, args); 73 | 74 | } 75 | 76 | } 77 | ``` 78 | ### src/main/java/com/in28minutes/springboot/WelcomeController.java 79 | ``` 80 | package com.in28minutes.springboot; 81 | 82 | import org.springframework.beans.factory.annotation.Autowired; 83 | import org.springframework.web.bind.annotation.RequestMapping; 84 | import org.springframework.web.bind.annotation.RestController; 85 | 86 | @RestController 87 | public class WelcomeController { 88 | 89 | //Auto wiring 90 | @Autowired 91 | private WelcomeService service; 92 | 93 | @RequestMapping("/welcome") 94 | public String welcome() { 95 | return service.retrieveWelcomeMessage(); 96 | } 97 | } 98 | ``` 99 | ### src/main/java/com/in28minutes/springboot/WelcomeService.java 100 | ``` 101 | package com.in28minutes.springboot; 102 | 103 | import org.springframework.stereotype.Component; 104 | 105 | @Component 106 | public class WelcomeService { 107 | 108 | public String retrieveWelcomeMessage() { 109 | //Complex Method 110 | return "Good Morning updated"; 111 | } 112 | } 113 | ``` 114 | ### src/main/resources/application.properties 115 | ``` 116 | logging.level.org.springframework: DEBUG 117 | ``` 118 | -------------------------------------------------------------------------------- /Step04.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Understand Starter Parent 3 | - How to override things defined in Starter Parent 4 | - Other starter projects 5 | 6 | ## Starter Parent 7 | - Dependency Versions 8 | - Java Versions 9 | - Default Plugins 10 | 11 | ## Other Starter Projects 12 | - spring-boot-starter-web-services 13 | - spring-boot-starter-test 14 | - spring-boot-starter-jdbc 15 | - spring-boot-starter-security 16 | - spring-boot-starter-data-jpa 17 | - spring-boot-starter-data-rest 18 | - More at https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#using-boot-starter 19 | 20 | ## Useful Snippets and References 21 | First Snippet 22 | ``` 23 | 24 | org.springframework.boot 25 | spring-boot-starter-parent 26 | 1.4.0.RELEASE 27 | 28 | ``` 29 | -------------------------------------------------------------------------------- /Step05.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - Spring Boot vs Spring 3 | - What Spring Boot is Not! 4 | 5 | ## Spring Boot vs Spring 6 | 7 | ### Spring 8 | - Spring is just a dependency injection framework. Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments. 9 | - First half of the 2000 decade! EJBs 10 | - EJBs were NOT easy to develop. 11 | - Write a lot of xml and plumbing code to get EJBs running 12 | - Impossible to Unit Test 13 | - Alternative - Writing simple JDBC Code involved a lot of plumbing 14 | - Spring framework started with aim of making Java EE development simpler. 15 | - Goals 16 | - Make applications testable. i.e. easier to write unit tests 17 | - Reduce plumbing code of JDBC and JMS 18 | - Simple architecture. Minus EJB. 19 | - Integrates well with other popular frameworks. 20 | 21 | ### Applications with Spring Framework 22 | - Over the next few years, a number of applications were developed with Spring Framework 23 | - Testable but 24 | - Lot of configuration (XML and Java) 25 | - Developing Spring Based application need configuration of a lot of beans! 26 | - Integration with other frameworks need configuration as well! 27 | - In the last few years, focus is moving from monolith applications to microservices. We need to be able to start project quickly. Minimum or Zero start up time 28 | - Framework Setup 29 | - Deployment - Configurability 30 | - Logging, Transaction Management 31 | - Monitoring 32 | - Web Server Configuration 33 | 34 | ### Spring Boot 35 | - Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”. 36 | - We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. 37 | - Example Problem Statements 38 | - You want to add Hibernate to your project. You dont worry about configuring a data source and a session factory. I will do if for you! 39 | - Goals 40 | - Provide quick start for projects with Spring. 41 | - Be opinionated but provide options. 42 | - Provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration). 43 | 44 | #### What Spring Boot is NOT? 45 | - It’s not an app or a web server 46 | - Does not implement any specific framework - for example, JPA or JMS 47 | - Does not generate code 48 | 49 | -------------------------------------------------------------------------------- /Step06.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/Step06.zip -------------------------------------------------------------------------------- /Step08.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/in28minutes/SpringBootForBeginners/96aac7f51218090c1fa45747b9b48de5e0faabac/Step08.zip -------------------------------------------------------------------------------- /Step09.md: -------------------------------------------------------------------------------- 1 | ## What You Will Learn during this Step: 2 | - I hate the fact that I've to stop and start the server each time.
