Akka - 对象序列化期间的 StackOverflowError [英] Akka - StackOverflowError during object serialization

问题描述

我遇到了超过 2 天的问题.当我在参与者之间交换消息时，正在指责 JVM 堆栈溢出.

I'm with a problem that extends for more than 2 days. When I'm exchanging messages between actors, is accusing the JVM stack overflow.

我的消息是一个有很多链接的对象(在一个链表中链接在一起的 10000 多个子对象).即，具有 Neo4J 关系的对象.

My message is an object with many links (10000+ child objects linked together in a linked list). Namely, an object with Neo4J relationships.

错误是这样的:

有没有人对此有任何解决方案?

Does anyone have any solution for this?

谢谢

推荐答案

您使用的是 java.util.LinkedList 还是您自己的自定义链表?如果是后者，您需要为它编写一个自定义的 writeObject() 方法，以避免在没有时发生的递归.

Are you using java.util.LinkedList, or a custom linked list of your own? If the latter, you need to write a custom writeObject() method for it that avoids the recursion that would happen if you didn't have one.
