Dubbo中使用服務消費者調用生產者

接上一篇博客Dubbo快速入門 發佈服務、啓動服務

創建一個maven項目名字爲 vhukze-order-dubbo-service

引入與上一篇博客中服務生產者一樣的依賴

<dependencies>
		<dependency>
			<groupId>com.vhukze</groupId>
			<artifactId>vhukze-member-public-dubbo-api</artifactId>
			<version>0.0.1-SNAPSHOT</version>

在resources文件夾下創建一個配置文件 consumer.xml

內容如下          

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://code.alibabatech.com/schema/dubbo
       http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
	<!--服務名稱 定義了提供方應用信息，用於計算依賴關係；在 dubbo-admin 或 dubbo-monitor 會顯示這個名字，方便辨識 -->
	<dubbo:application name="order-consumer" />
	<!--向zookeeper訂閱provider的地址，由zookeeper定時發送 -->
	<dubbo:registry address="zookeeper://localhost:2181" />
	<!--使用 dubbo 協議調用定義好的 api.PermissionService 接口 -->
	<dubbo:reference id="memberService"
		interface="com.vhukze.api.member.service.MemberService" />
</beans>

創建一個類在com.vhukze.orderTest包下

package com.vhukze.orderTest;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.vhukze.api.member.service.MemberService;

public class OrderToMemberTest {
	public static void main(String[] args) {
		//加載配置文件
		ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("consumer.xml");
		
		//獲得對象
		MemberService memberService = app.getBean(MemberService.class);
		
		//調用方法
		System.out.println("訂單服務調用會員服務返回結果："+memberService.getUser(5l));
	}
}

啓動zookeeper，啓動會員服務（生產者）

運行main方法  結果：
