Spring Cloud中怎么實現zuul網關服務,針對這個問題,這篇文章詳細介紹了相對應的分析和解答,希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
工程創建 cloud-gateway-zuul。還是基于之前的工程 pom文件導入

創建GatewayZuulApplication啟動類
package com.xian.cloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; import org.springframework.cloud.openfeign.EnableFeignClients; /** * <Description> * * @author xianliru@100tal.com * @version 1.0 * @createDate 2019/10/29 10:52 */ @EnableZuulProxy @EnableFeignClients @EnableDiscoveryClient @SpringBootApplication public class GatewayZuulApplication { public static void main(String[] args) { SpringApplication.run(GatewayZuulApplication.class,args); } }
創建 bootstrap.yml
