概述

是什么

Zuul包含了对请求的路由和过滤两个最主要的功能:
其中路由功能负责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进行整合,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服务最终还是会注册进Eureka
 
提供=代理+路由+过滤三大功能

能干嘛

路由 过滤

hosts修改

127.0.0.1  myzuul.com

主启动类

package com.atguigu.springcloud;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
 
@SpringBootApplication
@EnableZuulProxy
public class Zuul_9527_StartSpringCloudApp
{
  public static void main(String[] args)
  {
   SpringApplication.run(Zuul_9527_StartSpringCloudApp.class, args);
  }
}

@EnableZuulProxy

启动

三个eureka集群

一个服务提供类microservicecloud-provider-dept-8001

一个路由

测试

不用路由

http://localhost:8001/dept/get/2

启用路由

http://myzuul.com:9527/microservicecloud-dept/dept/get/2

路由访问映射规则

工程microservicecloud-zuul-gateway-9527

代理名称

YML

before
http://myzuul.com:9527/microservicecloud-dept/dept/get/2
 
 
zuul: 
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**
 
after
http://myzuul.com:9527/mydept/dept/get/1

此时问题

路由访问OK

http://myzuul.com:9527/mydept/dept/get/1

原路径访问OK

http://myzuul.com:9527/microservicecloud-dept/dept/get/2

原真实服务名忽略

YML

zuul: 
  ignored-services: microservicecloud-dept 
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**

单个具体,多个可以用"*"

zuul: 
  ignored-services: "*"
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**

设置统一公共前缀

YML

zuul: 
  prefix: /atguigu
  ignored-services: "*"
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**

http://myzuul.com:9527/atguigu/mydept/dept/get/1
