# my-dubbo-demo1
1.The demo uses multicast as the registry since it is simple and does not require to extra installation
<dubbo:registry address="multicast://224.5.6.7:1234"/>
2.http://code.alibabatech.com/schema/dubbo这个地方和官网的不一样，因为使用的版本不同，需根据dubbo的jar包中的dubbo.xsd确定
来总结一下步骤：
1.三个模块，api 、provider、consumer
2.provider 、consumer都依赖api,provider实现api中的接口
3.provider暴露服务：
1.use multicast registry center to export service
2.use dubbo protocol to export service on port 20880
3.spring配置bean:<bean id="demoService" class="com.dr.service.DemoServiceImpl"/>实现接口的类
4.暴露服务接口：declare the service interface to be exported
<dubbo:service interface="com.dr.api.DemoService" ref="demoService"/>
4.service端的应用程序：加载spring配置，context.start()，阻塞程序，使得服务一直运行
5.消费端的应用程序：
1.编写spring配置文件:
use multicast registry center to discover service，
注册到zookeeper:<dubbo:registry address="multicast://224.5.6.7:1234"/>
generate proxy for the remote service
<dubbo:reference id="demoService" check="false" interface="com.dr.api.DemoService"/>
2.加载spring配置文件，启动，调用
