1、创建一个Maven项目，添加一个parent，代码如下
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.4.RELEASE</version>
</parent>
2、添加一个依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
3、配置java版本，若不填，默认1.6
<build>
<!-- 配置java版本 不配置的话默认父类配置的是1.6-->
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
4、新建一个java文件
package com.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @RestController 相当于@Controller和@RequestBody
*
*/
@RestController
@EnableAutoConfiguration
public class HelloController {
@RequestMapping("/hello")
public String hello(){
return "Hello Word SpringBoot";
}
public static void main(String[] args) {
SpringApplication.run(HelloController.class, args);
}
}
最后run运行
