一、什么是网关
Zuul的主要功能是路由转发和过滤器。路由功能是微服务的一部分,比如/api/user转发到到user服务,/api/shop转发到到shop服务。zuul默认和Ribbon结合实现了负载均衡的功能, 类似于nginx转发。
二、搭建SpringCloud网关
2.1 创建工程service-zuul 目录展示
2.2 导入依赖
<!--eureka依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-zuul</artifactId> </dependency> <dependencyManagement> <dependencies> <!--springCloud依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Greenwich.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
2.3 application.yml配置文件
2.4 StartSpringCloudZuul启动类
package com.zn; 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; @EnableEurekaClient @SpringBootApplication @EnableZuulProxy public class StartSpringCloudZuul { public static void main(String[] args) { SpringApplication.run(StartSpringCloudZuul.class,args); } }
2.5 效果展示
