三、打包Dubbo服務
1、使用maven進行打包，先運行clean 再運行install
四、啓動Dubbo服務
1、把jar文件和lib文件夾拷貝到C盤DemoServiceJars目錄下
2、命令行定位到C盤DemoServiceJars目錄下，執行java -jar dub-service-demo.jar
3、ZooKeeper檢測到該服務
4、Linux啓動Dubbo的方式也是執行：java -jar dub-service-demo.jar&
五、注意事項
1、配置文件dubbo-provider.xml必須放在resource-->spring文件夾下，否則dubbo就算顯示啓動成功， 實際上也沒有啓動
