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

application中相关配置如下：
spring.application.name=service-demo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=http://localhost:8060/eureka
server.port=8070
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;
/**

* @Desc

/**

*/
@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);
}
}

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
