Thanks in advance. I try to use the "dubbo" to invoke a method which is override.But the console tell me that "Caused by: com.caucho.hessian.io.HessianProtocolException: '' is an unknown code". Search Engines told me that error may cased by "hessian" is not support override method default.So i try to set this property ,"isOverloadEnabled".But i can not find the way to set. I am searching for a long time on net. But no use. Please help or try to give some ideas how to achieve this.

That's xml content :

<dubbo:protocol name="hessian" port="30002" threads="200" />

<dubbo:service ref="ossServiceImpl" interface="com.fragment.dede.apis.OssService" protocol="hessian"/>

You have to use HessianProxyFactory. Then call:

factory.setOverloadEnabled(true);
