  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@EnableAutoConfigurationpublic 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
