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][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

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

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
