springcloud學習服務網關zuul-初步學習

1.打開idea建立springclud的zuul工程

選中上圖的zuul，進行建立

建立成功

2.進行初步測試

啓動類增長網關支持

package com.example.zuul;

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

@SpringBootApplication
@EnableZuulProxy  //支持網關路由
public class ZuulApplication {

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

}

3. 配置文件，增長相關配置，轉發路由到網址

spring.application.name=gateway-service-zuul
server.port=8888

#這裏的配置表示，訪問/it/** 直接重定向到http://www.ityouknow.com/**
#zuul.routes.baidu.path=/it/**
#zuul.routes.baidu.url=http://www.ityouknow.com/
#zuul.routes.hello.path=/api/**
#zuul.routes.hello.url=http://localhost:9001/

啓動項目，請求，進行測試http://localhost:8888/it/spring-cloud  請求成功

接下來，進行改造，改形成一個微服務，註冊到eureka

1.pom文件，增長依賴eureka

         </plugin>
      </plugins>
   </build>

</project>

2.配置文件，增長配置，註冊到eureka。而且對以前的微服務，根據路由，轉發不一樣的id

spring.application.name=gateway-service-zuul
server.port=8888

#這裏的配置表示，訪問/it/** 直接重定向到http://www.ityouknow.com/**
#zuul.routes.baidu.path=/it/**
#zuul.routes.baidu.url=http://www.ityouknow.com/
#zuul.routes.hello.path=/api/**
#zuul.routes.hello.url=http://localhost:9001/

zuul.routes.api-a.path=/producer/**
zuul.routes.api-a.serviceId=spring-cloud-producer

eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

3.啓動註冊中心，啓動spring-cloud-producer 服務，啓動zuul服務。進行訪問

 

ok了，zuul初級的集成已經完成了。
