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集成了Tomcat、Jetty等Servlet 3.0+的Web容器。

10. Installing Spring Boot

Spring Boot以及Spring Boot CLI的各种安装方法

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提供了所需的依赖，并且可以省略依赖的版本。

spring-boot-starter-web可以用来生成web程序，自带tomcat等。

2. 代码：

 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控制器，直接把字符串渲染后返回给调用者
 7 @EnableAutoConfiguration // 自动配置
 8 public class Example {
 9     @RequestMapping("/") // 路由
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 }

通过以下命令启动

mvn spring-boot:run
