Eureka客户端启动，将服务注册到eureka服务端注册中心上

maven工程结构如下

pom文件如下

</project>

application中相关配置如下：

spring.application.name=service-demo
eureka.client.service-url.defaultZone=http://localhost:8060/eurekaserver.port=8070

这里的spring.application.name就是注册的服务名称，后面消费者就可以通过这个名称来调用服务了
eureka.client.service-url.defaultZone这个是eureka注册中心服务器的地址，客户端和消费者后面都会用到这个地址的

server.port就是服务端口号，表明该客户端对外提供的服务是8070端口

代码如下：

package com.chiwei.eureka;import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;/*** @Type Bootstrap.java* @Desc * @author chiwei* @date 2017年11月9日 下午5:24:53* @version */
/*** @author chiwei**/
@EnableDiscoveryClient
@SpringBootApplication
public class Client {/*** 主函数入口* @param args*/public static void main(String[] args) {SpringApplication app = new SpringApplication(Client.class);// 不启动web服务// app.setWebEnvironment(false);app.run(args);}}@RestController
class ServiceRestController {@Value("${server.port}")private int serverPort;@RequestMapping(value = "/hello", method = RequestMethod.GET)public String hello() {return "Hello, Spring Cloud! My port is " + String.valueOf(serverPort);}}/*** Revision history* -------------------------------------------------------------------------* * Date Author Note* -------------------------------------------------------------------------* 2017年11月9日 chiwei create*/

启动该客户端，然后去前一篇的服务端地址访问查看页面信息
