在引入dubbo項目宾尚，Spring boot 無法啟動
類中dubbo注解
@Service(version = "1.0.0", application = "${dubbo.application.id}", protocol = "${dubbo.protocol.id}", registry = "${dubbo.registry.id}", timeout = 10000, retries = 0)
報錯信息：
Caused by: java.lang.ClassNotFoundException: org.I0Itec.zkclient.IZkStateListener
原因：缺少zookeeper一個包
<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
<version>0.1</version>
</dependency>
引入依賴后，程序正常啟動煌贴，服務(wù)注冊成功！
