**

provider项目

** 1、需要调用的接口 package service.api;

public interface DemoService { /*** * 对外的接口 * @param name * @return */ public String sayHello(String name); }

2、调用接口的实现 package service.api.impl;

import org.springframework.stereotype.Service;

import service.api.DemoService;

@Service("demoService") public class DemoServiceImpl implements DemoService{

public String sayHello(String name) {	return "你真棒  居然成功搭建了dubbo的架构";}

}

3、dubbo-provider.xml的配置

<?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" xmlns:context="http://www.springframework.org/schema/context" 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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" default-autowire="byName">

<dubbo:protocol id="protocol" name="dubbo" port="25000"

</beans>

**

consumer项目

** 1、接口 package service.api;

public interface DemoService { /*** * 对外的接口 * @param name * @return */ public String sayHello(String name); }

2、调用dubbo服务 package service.api;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ConsumerDemo {

public static void main(String[] args) {		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "classpath:dubbo-consumer.xml" });  	context.start();  	DemoService demoService = (DemoService) context.getBean("demoService"); //            String str=demoService.sayHello(""); //       System.out.println(str);        try {		Thread.sleep(10000000);	} catch (InterruptedException e) {		// TODO Auto-generated catch block		e.printStackTrace();	} //暂停，每一秒输出一次}

}

3、dubbo-consumer.xml的配置文件

<?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">

</beans>
