1、创建项目，选择Spring Initializr，点击Next
2、填写项目信息，点击Next
3、选择Cloud Discovery --> Eureka Discovery,点击Next
4、点击Finish，完成项目创建
5、查看pom文件，可以看到项目已经自动加上EurekaClient相关依赖
除以上方法外，也可以创建普通的maven项目，然后手动加上这个依赖，完成EurekaClient项目的创建。
6、在项目的application启动类上加 @EnableEurekaClient注解
7、在application.properties配置文件中加入EurekaServer的配置信息，让该项目注册到对应的EurekaServer上。
####EurekaClient项目端口号
server.port=8762
####EurekaClient项目名称，对应EurekaServer页面中的Application名称
spring.application.name=eureka-client-demo
####EurekaServer Url
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
注意： 如果此时启动项目，会提示以下错误：
Unregistering application EUREKA-CLIENT-DEMO with eureka with status DOWN
启动日志信息如下：

解决方法：添加以下依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
8、再次启动项目，进入EurekaServer页面，可以看到EurekaClient已经成功注册到EurekaServer注册中心。至此，EurekaClient搭建完毕。
