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 eureka.client.service-url.defaultZone=http://localhost:8060/eureka server.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
