序列化swing / awt组件 [英] Serializing swing/awt components

问题描述

我正在尝试序列化JPanel，但每次我都会收到此错误：

I am trying to serialize a JPanel but everytime i get this error:

java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: javax.swing.GroupLayout  

你能告诉我，可能是什么问题或者序列化它的正确方法是什么。

Can you tell me, what could be the problem or what is the proper way of serializing it.

我做的很简单：

FOR Serializing：

FOR Serializing:

FileOutputStream f = new FileOutputStream("myfile.dat");
ObjectOutputStream ostream = new ObjectOutputStream(f);
Object object = panel;  //where panel is a JPanel type object
ostream.writeObject(object);
ostream.close();

现在进行反序列化：

File file = new File("myfile.dat");
ObjectInputStream in;
try {
   in = new ObjectInputStream(new FileInputStream(file));
   object = (JPanel) in.readObject();
   in.close();
} catch (Exception e2) {
   e2.printStackTrace();
}  

在最后一步读取序列化对象时遇到上述错误。是什么原因，或任何想法应该如何做到这一点？

while reading the serialized object in last step i encounter the above error. What is the reason, or any idea how is should do this?

推荐答案

GroupLayout ，似乎已添加到面板中，不可序列化。有几个选项（列出最少至最优惠）。

GroupLayout, which appears to have been added to the panel, is not serialisable. There are a few options (listed least to most favourable).

• 子类 GroupLayout 创建一个串行代理（参见Effective Java 2nd Ed）。这是一项相当多的工作，并且由于 GroupLayout 没有一套完整的getter and setters而变得复杂。

• Subclass GroupLayout to create a serial proxy (see Effective Java 2nd Ed). This is a fair bit of work, and is complicated by GroupLayout not having a complete set of "getters and setters".

使用可序列化的 LayoutManager 替换 GroupLayout 。 Java库中有功能但粗略的 GridBagLayout 。其他布局管理器可用。

Replace GroupLayout with a serialisable LayoutManager. There's the functional but rough GridBagLayout in the Java library. Other layout managers are available.

不要序列化 JPanel 。使AWT组件可序列化（以及整个JavaBeans的事情）是一个可笑的错误。

Don't serialise the JPanel. Making AWT components serialisable (and the whole JavaBeans thing) was a laughable mistake.
