本文介绍了使用Spring Cloud搭建Eureka服务注册中心的步骤，包括配置pom文件、在appcation.yml中设置服务名和注册中心地址，在启动类添加@EnableEurekaServer注解开启服务，最后通过访问特定地址验证搭建是否成功。

1.pom文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.wt</groupId>
  <artifactId>EurekaServer</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.2.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->

    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
  </properties>

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

      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
  </repositories>

2.appcation.yml 配置服务名以及注册中心地址等

server:
  port: 8888
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false #是否将自己注册到eureka server，构建集群环境时，需将自己注册到集群中，默认为true
    fetchRegistry: false #是否从eureka server获取注册信息，构建集群环境时，需同步其他eureka server节点，默认为true
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

3.启动类加上注解@EnableEurekaServer，开启eureka server

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApp {

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

4.访问http://localhost:8888/ 弹出此页面表示搭建服务注册中心成功
