spring-cloud入门之eureka-server（服务发现）

前言

eureka是一个服务发现和注册框架，细的来说，我们可以分为eureka-server（服务发现）和eureka-client（服务注册）两个，本次我们对eureka-server（服务发现）做一个项目搭建，作为spring-cloud的开篇。

项目结构

maven结构大家应该都清楚（不清楚的需要补一补，百度关于maven的文章不计其数），下面我们来看一看这些关键文件的配置

代码编写

springcloudeurekaserverapplication.java

package com.cppba;

import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
import org.springframework.cloud.netflix.eureka.server.enableeurekaserver;

@enableeurekaserver
@springbootapplication
public class springcloudeurekaserverapplication {

  public static void main(string[] args) {
    springapplication.run(springcloudeurekaserverapplication.class, args);
  }
}

application.properties

server.port=8761

eureka.instance.hostname=eureka-server
eureka.client.registerwitheureka=false
eureka.client.fetchregistry=false
eureka.client.serviceurl.defaultzone=http://${eureka.instance.hostname}:${server.port}/eureka/

到此项目搭建完成

启动项目

我们启动springcloudeurekaserverapplication中的main方法，访问http://127.0.0.1:8761

到此，eureka-server（服务发现）项目搭建成功
