首先创建一个maven项目，和创建一个Spring项目一样

在pom文件中引入相关的依赖，依赖是以前引过的

     
        
          
              
       
        org.springframework.boot
               
       
        spring-boot-starter-parent
               
       
        2.0.3.RELEASE
               
        
           
          
      
       4.0.0
          
      
       springboot-02
          
      
       war
          
      
       springboot-02 Maven Webapp
          
          
      
       http://www.example.com
          
          
              
       
        UTF-8
               
       
        UTF-8
               
       
        1.8
           
          
              
                   
        
         junit
                    
        
         junit
                    
        
         4.11
                    
        
         test
                
               
                   
        
         org.springframework.boot
                    
        
         spring-boot-starter-web
                
               
                   
        
         org.springframework.boot
                    
        
         spring-boot-starter-test
                    
        
         test
                
           
          
              
       
        springboot-02
           
      
     

编写的Controller和SpringBoot一样

package cn.studio.controller;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * Created by mycom on 2018/6/22. */@SpringBootApplication@RestControllerpublic class HelloController {    @RequestMapping("/hello")    public Object hello(){        return "你好我好";    }    public static void main(String[] args) {                SpringApplication.run(HelloController.class, args);    }}
