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
