部署开发,需要三部分:服务提供者、服务容器、服务消费者
本人用 eclipse 开发
1、服务提供者jar生成

<? 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"> <!-- 提供方应用信息,用于计算依赖关系 --> < dubbo:application name = "hello-world-app" /> <!-- 使用multicast广播注册中心暴露服务地址 --> < dubbo:registry address = "multicast://224.5.6.7:1234" /> <!-- 用dubbo协议在20880端口暴露服务 --> < dubbo:protocol name = "dubbo" port = "20880" /> <!-- 声明需要暴露的服务接口 --> < dubbo:service interface = "com.alibaba.dubbo.demo.DemoService" ref = "demoService" /> <!-- 和本地bean一样实现服务 --> < bean id = "demoService" class = "com.alibaba.dubbo.demo.provider.DemoServiceImpl" /> </ beans > |
C、生成jar包
右键项目名称->export->java ->jar file - > 点击下一步
按下图所示,进行选择
点击finish,jar包导出到路径:C:UsersmichaelDesktopapp.jar
注:jar包叫什么名字,没任何关系
2、部署服务容器:
下载
dubbo-demo-provider-2.5.4-SNAPSHOT-assembly.tar.gz
下载页面
http://alibaba.github.io/dubbo-doc-static/Download-zh.htm
注:可能下载不下来,我是从dubbo的QQ群里下载下来的
解压缩后,容器部署完成
3、部署服务
第2步中解压缩的目录,将第2步中的jar包,放入到 dubbo-demo-provider-2.5.4-SNAPSHOTconf或者dubbo-demo-provider-2.5.4-SNAPSHOTlib目录下
进入demo-provider-2.5.4-SNAPSHOTin
注:修改binstart.bat文件,classpath中加入:..confapp.jar
双击:start.bat
服务正式启动
4、在eclipse中写消费者程序测试部署的服务

import org.springframework.context.support.ClassPathXmlApplicationContext; import com.alibaba.dubbo.demo.DemoService; public class Consumer { /** * @param args */ public static void main(String[] args) { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( new String[] { "classpath:consumer.xml" }); context.start(); DemoService demoService = (DemoService) context.getBean( "demoService" ); // 获取远程服务代理 String hello = demoService.sayHello( "world" ); // 执行远程方法 System.out.println(hello); // 显示调用结果 } } |

C、启动
Consumer类中的main方法
D、OK,完事
