Posted 2021-03-20 XiangHuiBlog

构建 microservicecloud-eureka-7001 eureka服务注册中心Module

1.新建microservicecloud-eureka-7001

 

2.pom

   </dependency>
  </dependencies>
 
</project>

3.yml

 
server: 
  port: 7001
 
eureka:
  instance:
    hostname: localhost #eureka服务端的实例名称
  client:
    register-with-eureka: false #false表示不向注册中心注册自己。
    fetch-registry: false #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/        #设置与Eureka Server交互的地址查询服务和注册服务都需要依赖这个地址。
 

4.EurekaServer7001_App主启动类

package com.atguigu.springcloud;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 
@SpringBootApplication
@EnableEurekaServer//EurekaServer服务器端启动类,接受其它微服务注册进来
public class EurekaServer7001_App
{
  public static void main(String[] args)
  {
   SpringApplication.run(EurekaServer7001_App.class, args);
  }
}
 
 

5.测试

先要启动EurekaServer

http://localhost:7001/
