简介

zuul网关组件；如现在有两个微服务部署在异地，访问A服务ipA:8001/getData，访问B服务ipB:8002/getView，即需要访问多个ip和端口，添加zuul网关服务，则只需访问网关服务的ip和其端口即可；

实战

1、创建《zuul》模块

1.1、pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>cc.catface</groupId>
    <artifactId>simple-eureka</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>zuul</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>zuul</name>

  <dependencies>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!--zuul依赖-->
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    </dependency>
  </dependencies>
</project>

1.2、yml

server:
  port: 8062

spring:
  application:
    name: zuul

eureka:
  client:
    service-url:
      defaultZone: http://localhost:7000/eureka/

#zuul路由配置
zuul:
  routes:
    api-a:
      path: /ac/**
      serviceId: SERVER-ACCOUNT
    api-b:
      path: /or/**
      serviceId: SERVER-ORDER

1.3、application

application声明注解​​@EnableZuulProxy​​；

2、效果

分别启动《server-center》、《server-config》，《server-account》、《server-order》、《hystrix-dashboard》、《turbine-dashboard》、《zuul》，发起请求，发现通过网关服务的ip和端口可以完成对外部服务的访问；
