序列化包含对象的对象java [英] Serialize objects containing objects java

问题描述

我尝试序列化一个对象，该对象包含另一个本身可序列化的对象.

I try to serialize an object that contains an other object which is itself serializable.

有没有办法让它工作?当我序列化第一个对象时，指向另一个对象的指针似乎丢失了.

Is there a way to make it work ? The pointer to the other object seems to be lost when I serialize the first object.

推荐答案

这里有两个关于持久对象的规则:

Here are two rules concerning persistent objects:

• 规则 1:要持久化的对象必须实现 Serializable 接口或从其对象层次结构继承该实现
• 规则 2:要持久化的对象必须将所有不可序列化的字段标记为瞬态

查看文章 发现 Java 序列化 API 的秘密".它包括源代码和对序列化过程的很好的解释.

Check the article "Discover the secrets of the Java Serialization API". It's include source code and a good explanation of the serialization process.
