1、ServiceMemberApplication主要是SpringBoot的入门类，主类直接自动加载Spring配置，最重要的是@EnableEurekaClient

package com.ml0115;

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

@SpringBootApplication
@EnableEurekaClient
public class ServiceMemberApplication {

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

}

2.MemberController，进行前端的请求处理

package com.ml0115.controller;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MemberController {

 
  @Value("${server.port}")
  private String serverPort;

  @RequestMapping("/getUserList")
  public List<String> getUserList() {
    List<String> listUser = new ArrayList<String>();
    listUser.add("zhangsan");
    listUser.add("lisi");
    listUser.add("yushengjun");
    listUser.add("端口号:"+serverPort);
    return listUser;
  }


}

3.application.yml配置，生命服务的启动端口号和应用名称

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8888/eureka/
server:
  port: 8762
spring:
  application:
    name: service-member
