## zuul ##

**zuul包含了对请求的路由和过滤两个最主要的功能:**  
其中路由功能复杂将外部请求转发到具体的微服务实例上,是实现外部访问统一入口的基础,而过滤器功能则负责对请求的处理过程进行干预,是实现请求校验,服务聚合等功能的基础,Zuul和Eureka进行整个,将zuul自身注册为eureka服务治理下的应用,同时从eureka中获得其他微服务的消息,也即以后的访问微服务都是通过zuul跳转后获得;

**注意:Zuul服务最早还是会注册进Eureka**

## 提供=代理+路由+过滤三大功能 ##

## 路由的基本配置 ##

## 新建microservicecloud-zuul-gateway-9527 ##

## 启动 ##

1.  三个eureka集群
2.  一个服务提供类microservicecloud-provider-dept-8001
3.  一个路由

## 测试 ##
