六（1）springcloud之zuul路由网关

拼搏现实的明天。 2023-07-05 10:15 22阅读 0赞

# 1、Zuul介绍 #

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

# 2、基本路由配置 #

1、新建Module模块microservicecloud-zuul-gateway-9527

2、pom文件

    </project>

3、yml配置

4、修改host文件

127.0.0.1  myzuul.com

5、主启动类

package cn.jiatp.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) {
    		// TODO Auto-generated method stub
    		 SpringApplication.run(Zuul_9527_StartSpringCloudApp.class, args);
    
    	}
    
    }

6、启动测试：

分别启动三个eureka集群、一个服务提供类microservicecloud-provider-dept-8001、microservicecloud-zuul-gateway-9527

浏览器中测试：[http://myzuul.com:9527/microservicecloud-dept/dept/get/2][http_myzuul.com_9527_microservicecloud-dept_dept_get_2]

# 3、路由访问映射规则 #

修改yml

server: 
      port: 9527
     
    spring: 
      application:
        name: microservicecloud-zuul-gateway
     
    eureka: 
      client: 
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka  
      instance:
        instance-id: gateway-9527.com
        prefer-ip-address: true 
     
     
    info:
      app.name: jiatp-microservicecloud
      company.name: www.jiatp.club
      build.artifactId: $project.artifactId$
      build.version: $project.version$   
      
    # 路由访问映射规则
    zuul: 
      prefix: /jiatp  #设置统一公共前缀
      ignored-services: microservicecloud-dept # 多个可用 * 代替
      routes: 
        mydept.serviceId: microservicecloud-dept
        mydept.path: /mydept/**

路由访问映射从：[http://myzuul.com:9527/microservicecloud-dept/dept/get/2][http_myzuul.com_9527_microservicecloud-dept_dept_get_2]\---->[http://myzuul.com:9527/mydept/dept/get/2][http_myzuul.com_9527_mydept_dept_get_2](原真实服务名忽略)---->[http://myzuul.com:9527/jiatp/mydept/dept/get/2][http_myzuul.com_9527_jiatp_mydept_dept_get_2](设置统一公共前缀)
