springcloud fegin和rabbot分别实现微服务（二）

前面一篇文章写了第一种实现微服务架构现在实现第二种依然是傻瓜

第一篇博文链接 https://blog.csdn.net/qq_41684939/article/details/89602525

这是基于上一篇博文写的

提供者启动类

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@EnableEurekaClient
@ComponentScan(basePackages = {"com.example"})
public class Demo1Application {

	public static void main(String[] args) {
		SpringApplication.run(Demo1Application.class, args);
	}

}

提供者 controller

package com.example.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;


@RequestMapping("/fregin")
@RestController
public class ServiceController {

	
	 @GetMapping("/hello")
	    public String hello() {
	        String s="测试开源框架fregin"+"这是service层：port="+"8814";
	        return s ;
	    }


}
