1.Zuul简介
Zuul包含了对请求的路由和过滤两个最主要的功能。
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。
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：Zuul服务最终还是会注册进Eureka
Zuul提供代理、路由、过滤三大功能。

2.Zuul配置
(1).创建工程
新建Module模块microservicecloud-zuul-gateway-9527
(2).配置pom

(3).applicaiton.yml
server: port: 9527
spring: application: name: microservicecloud-zuul-gateway
eureka: client: service-url: defaultZone: instance: instance-id: gateway-9527.com prefer-ip-address: true
info: app.name: hosystem-microcloud company.name: www.hosystem.com build.artifactId: $project.artifactId$ build.version: $project.version$ |
(4).修改hosts
127.0.0.1 myzuul.com |
(5).主启动类
创建主启动类Zuul_9527_StartSpringCloudApp，并添加注解@EnableZuulProxy.
package com.hosystem.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); } } |
(6).启动项目
[1].启动eureka7001、eureka7002、eureka7003
启动microservicecloud-eureka-7001、microservicecloud-eureka-7002、microservicecloud-eureka-7003
[2].启动provider8001
启动microservicecloud-provider-dept-8001
[3].启动zuul9527
启动microservicecloud-zuul-gateway-9527
(7).测试
[1].未启用路由
[2].启动路由
