在Java中将Child类设置为Non Serializable [英] Making Child classes as Non Serializable in java

问题描述

我有一个实现Serializable的类。现在我扩展了这个类，我希望这个扩展类不是Serializable。那怎么办呢？

I have a class which implements Serializable. Now I extends this class and I want this extended class to be non Serializable. So how to do it?

例如。我有

class A implements Serializable.

我有

class B extends A.

但我希望B类是非可序列化的。

But I want class B to be Non Serializable.

推荐答案

正如其他人已经说清楚的那样， Serializable 类为非 - 可序列化。

As others have made clear, it's not possible for a subclass of a Serializable class to be non-Serializable.

如果你想要的是子类的属性不是序列化，一个选项是使它们都是瞬态的。

If what you want is for the subclass' attributes not to be serialized, one option is to make them all transient.

如果你需要更多（你不希望序列化超类字段），覆盖 writeObject（ObjectOutputStream）和 readObject（ObjectInputStream），如此处所述 - https://web.archive.org/web/20120626144013/http://java .sun.com / developer / technicalArticles / ALT / serialization

If you need more than that (you don't want super class fields to be serialized), override writeObject(ObjectOutputStream) and readObject(ObjectInputStream) as outlined here - https://web.archive.org/web/20120626144013/http://java.sun.com/developer/technicalArticles/ALT/serialization
