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.****.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
不懂得可以看

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：

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
