我序列化对象时的StackOverflowError [英] StackOverflowError when i serialize an object

问题描述

我想用这种方法来保护一个对象：

I want to seriliaze an object with this method :

public void serializ(CRDT m) throws IOException {
    ByteArrayOutputStream byteOutput = new ByteArrayOutputStream();
    ObjectOutputStream stream = new ObjectOutputStream(byteOutput);
    stream.writeObject(m);
    sumMemory = byteOutput.size();

    stream.flush();
    stream.close();
    byteOutput.flush();
    byteOutput.close();
}

我有一个例外 java.lang.StackOverflowError

Exception in thread "main" java.lang.StackOverflowError

    at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1518)

    ...

我读了一些论坛，我需要重新实现 writeObject / readObject 方法。
它是唯一可行的解​​决方案吗？以及如何重新实现 writeObject / readObject

I read some forum that i need to reimplementing the writeObject / readObject methods. Is it the only possible solution ? and how to reimplementing the writeObject / readObject

我要序列化的对象是：
http://pastebin.com/D1kEidtn

My object to serialize is : http://pastebin.com/D1kEidtn

导致错误的两个类是：
pastebin.com/Sb3X0Quq 和在此输入链接描述

Two class that cause errors are : pastebin.com/Sb3X0Quq and enter link description here

推荐答案

CRDT是超类被序列化的对象m。
错误是从CRDT派生的类似乎有自己的引用，导致无限递归

你在堆栈跟踪中看到。

Tipp找出对象CRDT m的类：通过使用调试器，或在serialize（）方法的beginn处添加System.out.println（m.getClass（））。
然后当你知道这个类时，检查对象是否有对它自己的引用。

CRDT is the superclass of the Object m which is serialized. The error is that the class that derives from CRDT seems to have a reference to itself, leading to an endless recursion
You see that in the stack trace.
Tipp find out the class of The object CRDT m: by either using the debugger, or adding an System.out.println(m.getClass()) at the beginn of your serialize() method. Then when you know the class, check wheter the object has a reference to itself.
