<h3 dir="auto">Expected Result</h3>
<p dir="auto">What do you expected from the above steps？</p>
<h3 dir="auto">Actual Result</h3>
<p dir="auto">WrapperUtils.needWrapper(Object obj){<br>
return needWrapper(obj.getClass());  //这里obj 是null报错<br>
}<br>
因为NettyClientHandler.userEventTriggered()<br>
方法创建Request对象时候  mData 属性没有null<br>
请问是不是我使用protosubff 姿势不对</p>
