# 基于Eureka Server实现服务注册 #

## 引入Eureka Server依赖 ##

<dependencies>
    
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    
    </dependencies>

注意：这里不需要指定`Eureka Serve`的版本，在父项目中引用了SpringCloud的版本。

## 创建application.yml文件 ##

server:
      port: 8761
    
    eureka:
      instance:
        hostname: localhost
      client: 
        register-with-eureka: false  # 表示不向注册中心注册
        fetch-registry: false # 由于注册中心的职责就是维护服务实例，所以它不需要去检索服务
        service-url:
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

## 创建Eureka Server启动类 ##

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class EurekaServerApplication { 
        public static void main(String[] args) throws Exception {
            SpringApplication.run(EurekaServerApplication.class, args);
        }
    }

## 启动测试 ##

启动`EurekaServerApplication`类，通过访问[http://localhost:8761/][http_localhost_8761]来验证Eureka Server是否成功。  
如果成功，将会出现以下页面：
