统一由网关进行拦截判断

要不放到每个服务里面就很不合适了 冗余

主要的：

<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    		</dependency>

zuul和eureka都是基于netfix里面开源出来的

网关有公网ip 其他的服务没有 但是 网关和服务处于局域网内  客户端访问时候经过网关 通过网关去实现

###注册 中心
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8100/eureka/
    server:  ##api网关端口号
      port: 80
    ###网关名称
    spring:   ##网关服务名称
      application:
        name: service-zuul
    ### 配置网关反向代理    
    zuul:
      routes:
        api-member:  ##随便写的  用以区分
         ### 以 /api-member/访问转发到会员服务   通过别名找
         path: /api-member/** serviceId: app-toov5-member ##别名 如果集群的话 默认整合了ribbon 实现轮训 负载均衡
        api-order:   ##随便写的
        ### 以 /api-order/访问转发到订单服务 path: /api-order/** serviceId: app-toov5-order ##别名  path: /api-member/**
          serviceId: app-toov5-member  ##别名  如果集群的话  默认整合了ribbon 实现轮训 负载均衡
        api-order:   ##随便写的
            ### 以 /api-order/访问转发到订单服务
          path: /api-order/**

启动类：

package com.toov5;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
    
    @SpringBootApplication
    @EnableEurekaClient
    @EnableZuulProxy  //开启网关代理
    public class AppGateway {
       public static void main(String[] args) {
       SpringApplication.run(AppGateway.class, args);     
    }
    }
