Spring Cloud Zuul网关

前面已经简单介绍了搭建Eureka注册中心,Feign消费,Service提供者,那么外部调用的时候是直接走Feign来调用服务么?其实不然,后端接口并不会直接开方,而是通过一个统一网关服务,来映射请求的api,路由到相对应的服务.

沿用之前的服务来完成Zuul的测试.

一 : 新建一个boot工程命名为cloud-shop-gateway

二 : 在pom中添加依赖

<dependencies>
     <dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-eureka</artifactId>
      </dependency>
      <dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-zuul</artifactId>
	</dependency>
	</dependencies>

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

三 : 在Application启动类添加注解开启zuul服务

package cn.sh.daniel;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableZuulProxy   //添加注解支持网关路由
public class CloudShopGatewayApplication {

	public static void main(String[] args) {
		SpringApplication.run(CloudShopGatewayApplication.class, args);
	}
}

四 : 配置properties.yml

server:
  port: 6001
  
spring:
  application:
    name: cloud-shop-gateway

eureka:
  client:
    service-url:
      defaultZone: http://daniel-cloud-shop-eureka:[e-mail]:9001/eureka/,http://daniel-cloud-shop-eureka:[e-mail]:9002/eureka/

zuul:
  routes:
    api-user.path: /shop/user/**
    api-user.serviceId: cloud-shop-feign

api-user.path: /shop/user/**  指定对外映射的地址
api-user.serviceId: cloud-shop-feign 指定注册到注册中心的服务的serviceId

五 : 启动网关服务,测试

之前测试Feign的测试地址为: http://localhost:7001/user/findUser?name=cloud&password=001010

现在调用网关的地址为: http://localhost:6001/cloud-shop-feign/user/findUser?name=cloud&password=001010
可以看出和我们配置的映射关系
