SpringCloud学习系列-Eureka服务注册与发现(2)

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

1.新建microservicecloud-eureka-7001

2.pom

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   <version>0.0.1-SNAPSHOT</version>
  </parent>

  <artifactId>microservicecloud-eureka-7001</artifactId>

  <dependencies>
   <!--eureka-server服务端 -->
   <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-eureka-server</artifactId>
   </dependency>
   <!-- 修改后立即生效，热部署 -->
   <dependency>
     <groupId>org.springframework</groupId>

   <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-devtools</artifactId>
   </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/
