SpringCloud(六)网关代理

SpringCloud的网关主要用来代理多个服务访问的IP地址，就像是nginx一样nginx实现反向代理
要怎么玩呢？其实跟之前创建提供者一样的只是yml文件和pom.xml有点改变而已
首先要创建一个新的项目：
在这里插入图片描述
pom.xml的文件配置：就多加了一个网关的jar包，跟之前配置的提供者pom.xml没什么区别

yml文件的配置： QQ-user-consumer就是消费者的名称，如果有多个消费者可以配置多个 消费者名称: /user/**

      server:
  port: 8000
spring:
  application:
    name: QQ-zuul
eureka:
  client:
    service-url:
      defaultZone: http://root:111111@localhost:5000/eureka/  
zuul:
  routes:
    QQ-user-consumer: /user/**
    #QQ-user-consumer2: /user2/**
   #QQ-user-consumer3: /user3/**

在启动类添加一个 @EnableZuulProxy注解

 package com.accp.qqzuul;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableZuulProxy
public class QqZuulApplication {

    public static void main(String[] args) {
        SpringApplication.run(QqZuulApplication.class, args);
    }

}

然后就可以通过网关的端口号加user前缀访问浏览器了：
