Spring Cloud Gateway路由斷言實戰——Cookie路由斷言工廠

一 源碼位置

https://github.com/cakin24/spring-cloud-code/tree/master/ch17-2/ch17-2-4-gateway

https://github.com/cakin24/spring-cloud-code/tree/master/ch17-2/ch17-2-service

二 關鍵代碼

package cn.springcloud.book.gateway;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;


@SpringBootApplication
public class SpringCloudGatewayApplication {


   @Bean
   public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
      // 關鍵是下面這幾行代碼
      return builder.routes()
            .route("cookie_route", r -> r.cookie("chocolate", "ch.p")
                  .uri("http://localhost:8071/test/cookie"))
            .build();
   }


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

三 測試

1 啟動 ch17-2-4-gateway

2 啟動 ch17-2-service

3 Postman測試，界面如下圖：
