点击Next下一步

取自己喜欢的项目名点击Next

点击Finish

值得注意的是，个人建议服务端的版本号和客户端的版本号最好保持一致

添加application.yml内容

eureka:
  client:
    service-url:
      # 设置服务端地址
      defaultZone: http://localhost:8761/eureka/
spring:
  application:
    # 项目名称
    name: client

修改ClientApplication类

package ltd.xushen.client;

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

@SpringBootApplication
@EnableDiscoveryClient
public class ClientApplication {

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

}

下面启动Eureka Server端

在启动Eureka Client端，如果启动不成功，注意看pom文件，可能是你没导spring-boot-starter-web这个包

注册成功控制台可以看到204

DiscoveryClient_CLIENT/DVP-17C04:client - registration status: 204

访问：http://localhost:8761/服务端看到

就说明客户端成功注册到服务端了
