启动类package com.liu.news.artical.clnews;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**

• @author lx

• @version 1.0

• @description: TODO

• @date 2021/7/16 16:21
  */
  @SpringBootApplication
  @EnableDiscoveryClient
  public class ClnewsApplication {

  public static void main(String[] args) throws InterruptedException{

   SpringApplication.run(ClnewsApplication.class, args);
  

  }

}

业务类现在只加一个方法，hello

package com.liu.news.artical.clnews.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

/**

前端控制器

@author liuerchong

@since 2021-07-16
*/
@RestController
@RequestMapping("/cl-news")
public class ClNewsController {
@GetMapping("/hello")
public String hello(){
return “hello world”;
}
}
