【dubbo】消费者Consumer搭建

一.consumer搭建（可以web/jar）

1.新建Maven项目，groupId：com.dubbo.consumer.demo artifactId:demo projectName:dubboo-consumer-demo

2.新建class ：com.dubbo.consumer.demo.DemoAction

package com.dubbo.consumer.demo;import java.text.SimpleDateFormat;
import java.util.Date;
import com.dubbo.api.demo.*;
/*** Created by Administrator on 17-1-7.*/
public class DemoAction {private static DemoService demoService;public void setDemoService(DemoService demoService) {this.demoService = demoService;}public void start() throws Exception {for (int i = 0; i < Integer.MAX_VALUE; i ++) {try {String hello = demoService.sayHello("world" + i);System.out.println("[" + new SimpleDateFormat("HH:mm:ss").format(new Date()) + "] " + hello);} catch (Exception e) {e.printStackTrace();}Thread.sleep(2000);}}
}

3.添加配置文件spring-dubbo-consumer.xml

<?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"><dubbo:application name="dubbo-consumer-demo" ></dubbo:application><dubbo:registry address="zookeeper://127.0.0.1:2181" protocol="zookeeper"></dubbo:registry><dubbo:reference id="demoService" interface="com.dubbo.api.demo.DemoService" ></dubbo:reference></beans>

4.修改maven配置文件pom.xml,添加spring、dubbo、dubbo-api

<dependencies><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.4.10</version></dependency><dependency><groupId>com.github.sgroschupf</groupId><artifactId>zkclient</artifactId><version>0.1</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>3.2.16.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>3.2.16.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>3.2.16.RELEASE</version></dependency><dependency><groupId>com.dubbo.api.demo</groupId><artifactId>dubbo-interface</artifactId><version>1.0-SNAPSHOT</version></dependency></dependencies>

5.添加消费者Class DemoConsumer

import org.springframework.context.support.ClassPathXmlApplicationContext;public class DemoConsumer {public static void main(String[] args) {ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("META-INFO/spring-dubbo-consumer.xml");ctx.start();DemoService demoService = (DemoService) ctx.getBean("demoService");String hello = demoService.sayHello("world" + 1);System.out.println("[" + hello);ctx.close();}}
