基於spring-cloud-zuul的路由閘道器設定

由於微服務的日益增多,管理也會不方便,所以需要一個可以集中管理所有服務的功能(類似sevelet的filter),可以在此做同一的許可權入口管理

新建一個模組spring-cloud-gateway

增加zuul及相關依賴如下:

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

application.properties

server.port=8886
spring.application.name=gateway-service
eureka.client.service-url.defaultZone=http://localhost:8881/eureka/

#呼叫路徑服務的路徑
zuul.routes.eureka-client.path=/eureka-client/**

#呼叫服務的連結(不推薦,失去了均衡負載功能,只能使用一個服務)
#zuul.routes.lisiHello.url=http://localhost:8882/
#呼叫服務的id,即呼叫服務的名稱 spring.application.name
zuul.routes.eureka-client.serviceId=eureka-client

主方法只需要新增相關注解即可
application.java

package top.littlematch.gateway;

import org.springframework.boot.SpringApplication;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringCloudApplication
@EnableEurekaClient
@EnableZuulProxy
public class GatewayApplication {
    public static void main(String[] args){
        SpringApplication.run(GatewayApplication.class, args);
    }
}

依次啟動eureka-server,eureka-client,gateway-service再呼叫

http://localhost:8886/hello?name=match

瀏覽器返回:

hello! match
