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
package Consumer;/* * Copyright 1999-2011 Alibaba Group. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ import com.dubbo.api.demo.*; 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(); } }
二、总结
1.web或jar包形式发布消费者都可以
2.工程中涉及主要配置
A.consumer.xml 中引入API(interface)
B.pom.xml中引入API(Interface)jar包
C.接口实现在provider中完成,本地引入接口定义jar即可
D.java中import api package
