dubbo测试callback报错

[jinkelazzz]

按照callback例子写的，消费端调用时报Exception in thread "main" com.alibaba.dubbo.rpc.RpcException
Caused by: com.alibaba.dubbo.remoting.RemotingException: Fail to decode request due to: RpcInvocation [methodName=addListener, parameterTypes=[class java.lang.String, interface api.callback.CallbackListener], arguments=null, attachments={path=com.csc.microServe.api.callback.CallbackService, input=763, name=org.jeecg.Test, dubbo=2.8.4, version=0.0.0}]

服务端报这个错。可是CallbackListenerImpl就是dubbo CallbackListener的接口实现
