hessian2序列化bug #146

xiegengcai · 2015-07-24T11:27:13Z

直接RPC上传递Hibernate POJO时的bug，POJO有ORM注解。应该说是hessian本身的bug，

已解决

原来是hessian丢弃了ArrayList之外的集合。

参见：com.alibaba.com.caucho.hessian.io.CollectionSerializer#writeObject(Object, AbstractHessianOutput)

if (cl.equals(ArrayList.class)
|| ! _sendJavaType
|| ! Serializable.class.isAssignableFrom(cl))
  hasEnd = out.writeListBegin(list.size(), null);
else
  hasEnd = out.writeListBegin(list.size(), obj.getClass().getName());

修改为：

 if (obj instanceof Set
|| ! _sendJavaType
|| ! Serializable.class.isAssignableFrom(cl))
  hasEnd = out.writeListBegin(list.size(), null);
else
  hasEnd = out.writeListBegin(list.size(), obj.getClass().getName());

另外com.alibaba.com.caucho.hessian.io.MapSerializer#writeObject(Object, AbstractHessianOutput)也一样

@xiegengcai
你好首先感谢你提供的这个解决方案因为我现在也遇到了这个问题

请问一下
com.alibaba.com.caucho.hessian.io.MapSerializer#writeObject(Object, AbstractHessianOutput)
中

 if (cl.equals(HashMap.class)
	|| ! _isSendJavaType
	|| ! (obj instanceof java.io.Serializable))
      out.writeMapBegin(null);
    else
      out.writeMapBegin(obj.getClass().getName());

是要改成 :

 if (obj instanceof Set
|| ! _sendJavaType
|| ! Serializable.class.isAssignableFrom(cl))
  hasEnd = out.writeListBegin(list.size(), null);
else
  hasEnd = out.writeListBegin(list.size(), obj.getClass().getName());

还是修改为 :

    if (obj instanceof Map
	|| ! _isSendJavaType
	|| ! (obj instanceof java.io.Serializable))
      out.writeMapBegin(null);
    else
      out.writeMapBegin(obj.getClass().getName());

我目前是把他修改成了 :


      if (obj instanceof HashMap
                || !_isSendJavaType
                || !(obj instanceof java.io.Serializable)) {
            out.writeMapBegin(null);
        } else {
            out.writeMapBegin(obj.getClass().getName());
        }

期待你的回复, 再次感谢你提供的解决方案

@teemoer
CollectionSerializer 把ArrayList改成Set或Collection
MapSerializer把HashMap改成Map
