4.向注册中心注册服务
package com.jsxs;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;SpringBootApplicationEnableEurekaClientpublic class Demo03Application {public static void main(String[] args) {SpringApplication.run(Demo03Application.class, args);}}5.测试
先开启注册中心: eureka-7001;然后开启我们的服务提供者: demo2-8081;最后开启我们的服务消费者: demo3-80
