三、打包Dubbo服务

1、使用maven进行打包，先运行clean  再运行install

四、启动Dubbo服务

1、把jar文件和lib文件夹拷贝到C盘DemoServiceJars目录下

2、命令行定位到C盘DemoServiceJars目录下，执行java -jar dub-service-demo.jar

3、ZooKeeper检测到该服务

4、Linux启动Dubbo的方式也是执行：java -jar dub-service-demo.jar&


五、注意事项

1、配置文件dubbo-provider.xml必须放在resource-->spring文件夹下，否则dubbo就算显示启动成功， 实际上也没有启动

2、源码请从群中下载
