Spring Cloud之网关搭建-优快云博客

Spring Cloud之网关搭建

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

yml:

###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/**
      serviceId: app-toov5-order   ##别名

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);     
}
}
