App.class

package com.crazy_qu.hello;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;
    
    /**
     * Created by crazy on 2017/11/29.
     */
    @SpringBootApplication
    @ComponentScan(basePackages = {"com.crazy_qu.hello.controller"})
    public class App {
        public static void main(String[] args){
            SpringApplication.run(App.class, args);
        }
    }

AppController.class

package com.crazy_qu.hello.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    /**
     * Created by crazy on 2017/11/29.
     */
    @Controller
    public class AppController {
        @RequestMapping("/")
        @ResponseBody
        public String getResult(){
            return "hello world";
        }
    }

代码写好之后,直接在浏览器中访问:http://localhost:8080/
