添加继承和依赖  
pom.xml

<?xml version="1.0" encoding="UTF-8"?>
    <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">

        <groupId>com.pro</groupId>

        <version>1.0-SNAPSHOT</version>
          <parent>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-parent</artifactId>
                <version>1.5.1.RELEASE</version>
            </parent>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </dependency>
            </dependencies>
    
    </project>

java目录下新建controller包，此包放controller类

package controller;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    @EnableAutoConfiguration
    public class proController {
        @RequestMapping("pro")
        @ResponseBody
        public String pro(){
            return "这是第一个springboot项目";
        }
        
        public static void main(String[]args){
            SpringApplication.run(proController.class,args);
        }
    }

双击main函数，右键点击Run‘proController’
