2.创建控制器
package com.springboot.demo.controller;
import org.springframework.web.bind.annotation.*;
/**

@ClassName HelloController@Description TODO@Author yunshuodeng@Date 2019-05-05 15:41@Version 1.0**/
@RestController
br/>**/
@RestController
public class HelloController {@GetMapping
br/>@GetMapping
System.out.println("hello world");
return "hello world";
}
}
3.启动程序
package com.springboot.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**@ClassName ProviderApplication@Description 提供者主入口程序@Author yunshuodeng@Date 2019-01-21 10:34@Version 1.0**/
@SpringBootApplication
br/>**/
@SpringBootApplication
public static void main(String[] args){
SpringApplication.run(ProviderApplication.class,args);
}
}
