前面已經簡單介紹了搭建Eureka註冊中心,Feign消費,Service提供者,那麼外部呼叫的時候是直接走Feign來呼叫服務麼?其實不然,後端介面並不會直接開方,而是通過一個統一閘道器服務,來對映請求的api,路由到相對應的服務.

沿用之前的服務來完成Zuul的測試.

一 : 新建一個boot工程命名為cloud-shop-gateway

二 : 在pom中新增依賴

<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>
 

package cn.sh.daniel;

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

@SpringBootApplication
@EnableZuulProxy   //添加註解支援閘道器路由
public class CloudShopGatewayApplication {

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

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

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

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

五 : 啟動閘道器服務,測試

之前測試Feign的測試地址為: http://localhost:7001/user/findUser?name=cloud&password=001010

現在呼叫閘道器的地址為: http://localhost:6001/cloud-shop-feign/user/findUser?name=cloud&password=001010
可以看出和我們配置的對映關係
