java.lang.ClassNotFoundException

在引入dubbo项目，Spring boot 无法启动

类中dubbo注解

@Service(version = "1.0.0", application = "${dubbo.application.id}", protocol = "${dubbo.protocol.id}", registry = "${dubbo.registry.id}", timeout = 10000, retries = 0)

报错信息：

Caused by: java.lang.ClassNotFoundException: org.I0Itec.zkclient.IZkStateListener

原因：缺少zookeeper一个包

<dependency>

<groupId>com.github.sgroschupf</groupId>

<artifactId>zkclient</artifactId>

<version>0.1</version>

</dependency>

引入依赖后，程序正常启动，服务注册成功！
