Zuul路由网关 Zuul路由网关Zuul包含对请求的路由和过滤两个功能：路由功能：负责将外部请求转发到具体的微服务实例上，实现外部访问入口统一过滤：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注：Zuul服务也会注册到Eureka服务注册中心1、导入依赖<dependencies> <!--zuul--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zuul</artifactId> <version>1.4.7.RELEASE</version> </dependency> <!--hystrix--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> <version>1.4.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId> <version>1.4.7.RELEASE</version> </dependency> <!--Ribbon--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-ribbon</artifactId> <version>1.4.7.RELEASE</version> </dependency> <!--Eureka--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> <version>1.4.7.RELEASE</version> </dependency> <dependency> <groupId>com.sw</groupId> <artifactId>springcloud-api</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>2、application.yml配置server: port: 8888 spring: application: name: springcloud-zuul eureka: client: service-url: defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/ instance: instance-id: zuul8888.com prefer-ip-address: true info: app.name: springcloud-demo company.name: suaxi zuul: routes: mydept.serviceID: springcloud-provider-dept mydept.path: /mydept/** ignored-services: "*" #ignored-services: springcloud-provider-dept禁止使用原来的微服务名访问 #设置为 * 表示禁止使用全部的微服务ID进行访问3、SpringBoot启动类开启Zuul注解一般使用@EnableZuulProxypackage com.sw.springcloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; /** * @Author suaxi * @Date 2020/12/30 10:50 */ @SpringBootApplication @EnableZuulProxy //开启Zuul路由网关 public class ZuulApplication_8888 { public static void main(String[] args) { SpringApplication.run(ZuulApplication_8888.class,args); //http://www.xxx.com:8888/mydept/dept/get/1 } } 开启Zuul路由网关后，可通过：域名+端口号 访问微服务项目
