创建一个Maven工程，在pom.xml文件中加入依赖：    

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">      <modelVersion>4.0.0</modelVersion>      <groupId>springboot</groupId>      <artifactId>springboot</artifactId>      <version>0.0.1-SNAPSHOT</version>      <packaging>war</packaging>      <name>springboot</name>      <description />              <!-- 父依赖 -->      <parent>          <groupId>org.springframework.boot</groupId>          <artifactId>spring-boot-starter-parent</artifactId>          <version>1.2.2.RELEASE</version>      </parent>      <dependencies>          <dependency>              <!-- 导入jar包 -->              <groupId>org.springframework.boot</groupId>              <artifactId>spring-boot-starter-web</artifactId>          </dependency>      </dependencies>  </project>    

新建一个Controller来接受处理请求：    

package com.i.springboot.controller;     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  @EnableAutoConfiguration  public class TestController {             @RequestMapping(value="/test")      String home(){          return "hello world";      }             public static void main(String[] args) throws Exception {          SpringApplication.run(TestController.class, args);      }         }

[代码]这个Controller有一个main方法，直接运行这个main方法

[代码]直接访问http://localhost:8080/test    

浏览器输出 hello world,是不是简单方便
