搭建Eureka服务注册中心

新建Module

该Module为Maven项目，命名为microservice-eureka-server-2001

修改pom.xml

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

</project>

application.yml配置

在resources中新建application.yml

server:
  port: 2001
  context-path: /

eureka:
  instance:
    hostname: localhost #eureka注册中心实例名称
  client:
    register-with-eureka: false     #false 由于该应用为注册中心，所以设置为false,代表不向注册中心注册自己。
    fetch-registry: false     #false 由于注册中心的职责就是维护服务实例，它并不需要去检索服务，所以也设置为false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/       #设置与Eureka注册中心交互的地址，查询服务和注册服务用到

Eureka服务启动类

package com.ledao;

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

/**

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication_2001 {

    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication_2001.class, args);
    }
}
