我试图通过将Python对象发送到Java 来扩展本教程中的示例.虽然在Python和Java之间交换String对象的示例代码工作正常,但当我尝试用我自己的Python对象(Event)替换它时,会显示有关object_id的错误.

Python代码:

class Event(object):
   #some content here

stack = gateway.entry_point.getStack()
event = Event()

stack.push(event)

错误:

Traceback (most recent call last):
  File "/home/******/src/py4jSample.py", line 19, in <module>
   stack.push(event)
  File "/usr/local/lib/python2.7/dist-packages/py4j-0.7-py2.7.egg/py4j/java_gateway.py", line 423, in __call__
    [get_command_part(arg, self.pool) for arg in new_args])
  File "/usr/local/lib/python2.7/dist-packages/py4j-0.7-py2.7.egg/py4j/protocol.py", line 241, in get_command_part
    command_part = REFERENCE_TYPE + parameter._get_object_id()
AttributeError: 'Event' object has no attribute '_get_object_id'

知道如何解决这个问题吗？
