spring cloud基础知识 ——spring cloud 的路由网关(七)

开发工具idea，开发技术spring cloud

我的学习借鉴了 https://blog.csdn.net/sky786905664/article/details/78995068 

作者 Sky786905664 的一些文章

本节我们在之前的service-fegin上进行改造

路由网关简介：

Zuul的主要功能是路由转发和过滤器。可以转发请求的服务，zuul默认和Ribbon结合实现了负载均衡的功能。

首先我们先创建一个springboot功能模块叫service-zuul

依赖文件如下：

      </plugins>
   </build>

</project>

在启动器上加上注解@EnableZuulProxy开启路由网关

// 开启路由网关
@EnableZuulProxy
@EnableEurekaClient
@EnableDiscoveryClient
@SpringBootApplication
public class ServiceZuulApplication {

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

}

配置文件：

server.port=8086
eureka.client.serviceUrl.defaultZone=http://localhost:8081/eureka/
spring.application.name=service-zuul
zuul.routes.api-a.path=/api-a/**
zuul.routes.api-a.serviceId=service-ribbon
zuul.routes.api-b.path=/api-b/**
zuul.routes.api-b.serviceId=service-feign

启动之前功能模块的所有，看结果：

访问了service-ribbon

访问了service-fegin
