3:application.yml

server:port: 7101servlet:context-path: /
spring:application:name: spring-cloud-gatewaycloud:gateway:discovery:locator:enabled: true   #开启Eureka服务发现lower-case-service-id: true
eureka:client:service-url:defaultZone: ${EUREKA_URI:http://localhost:8761/eureka}instance:prefer-ip-address: true

4:启动类

package tigee;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;@SpringBootApplication
@EnableDiscoveryClient
public class ApplicationMain {static final Logger logger = LoggerFactory.getLogger(ApplicationMain.class);public static void main(String[] args) {logger.debug("服务启动..start......");SpringApplication.run(ApplicationMain.class, args);logger.debug("服务启动..end......");}}

3：启动看 注册中心

4：请求接口

http://localhost:7101/user-service/hello?name=12

 5:user-service 动多个端口

 

 再请求  localhost:7101/user-service/hello?name=12

 6：结果 是 端口 轮询显示
