[Spring Boot Reference Guide]読書ノート一Getting Started

8. Introducing Spring Boot
Goals of spring boot:

Provide a radically faster and widely accessible getting started experience for all Spring development.

Be opinionated out of the box, but get out of the way quickly as requirements start to diverge from the defaults.

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).

Absolutely no code generation and no requirement for XML configuration.

 
9. System Requirements
Spring Bootには、Tomcat、Jettyなどサーブレット3.0+のWebコンテナが統合されています.
 
10. Installing Spring Boot
Spring BootおよびSpring Boot CLIの各種取付方法
 
11. Developing your first Spring Boot application
1.
The spring-boot-starter-parent is a special starter that provides useful Maven defaults. It also provides a dependency-management section so that you can omit version tags for “blessed” dependencies.
Spring-boot-starter-parentは、必要な依存を提供し、依存バージョンを省略できます.
Spring-boot-starter-webは、tomcatなどを持参してwebプログラムを生成するために使用できます.
 
2.コード:

 1 import org.springframework.boot.*;

 2 import org.springframework.boot.autoconfigure.*;

 3 import org.springframework.stereotype.*;

 4 import org.springframework.web.bind.annotation.*;

 5 

 6 @RestController // REST   ，               

 7 @EnableAutoConfiguration //     

 8 public class Example {

 9     @RequestMapping("/") //   

10     String home() {

11         return "Hello World!";

12     }

13     public static void main(String[] args) throws Exception {

14         SpringApplication.run(Example.class, args);

15     }

16 }

次のコマンドで起動します.

mvn spring-boot:run
