application.yml配置

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
server:
  port: 8762
spring:
  application:
    name: service-hi

发布服务到Eureka

新建服务提供者

@SpringBootApplication
@EnableEurekaClient
@RestController
public class ServiceHiApplication {

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

	@Value("${server.port}")
	String port;

	@RequestMapping("/hi")
	public String home(@RequestParam String name) {
		return "hi " + name + ",i am from port:" + port;
	}

}

到这里，先启动以前Eureka注册中心服务

而后启动服务提供者

启动工程，打开http://localhost:8761 ，即eureka server 的网址：

你会发现一个服务已经注册在服务中了，服务名为SERVICE-HI ,端口为7862 这时打开 http://localhost:8762/hi?name=LLL丶禾羊 ，你会在浏览器上看到 : hi LLL丶禾羊,i am from port:8762

到这里就部署成功了
