Idea下SpringCloud2實驗（一、Eureka-服務注冊中心）

一、搭建Eureka注冊中心
1、創建SpringBoot項目

2、配置文件

2.1pom.xml

        </plugins>
    </build>

</project>

2.2 啟動文件

package com.jane.springcloudeureka;

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

@SpringBootApplication
@EnableEurekaServer
public class SpringcloudEurekaApplication {

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

}

2.3 application.properties

server.port=6001
eureka.instance.hostname=127.0.0.1
eureka.instance.prefer-ip-address=true
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

三、啟動，看到如下頁面，此時還沒有注冊服務
