序列化DefaultTreeModel
序列化DefaultTreeModel
提问于 2016-03-04 18:50:51
我试图序列化一个DefaultTreeModel，它由带有Strings的DefaultMutableTreeNode和各种自定义类和Enum组成，每个实现Serializable和类都使用这个；
private static final long serialVersionUID = 1L;这用于生成DefaultTreeModel
new DefaultTreeModel(
new DefaultMutableTreeNode("JTree") {
/**
*
*/
private static final long serialVersionUID = 1L;
{
DefaultMutableTreeNode event = new DefaultMutableTreeNode("Event");
for (EventType et: EventType.values()) {
DefaultMutableTreeNode eos = new DefaultMutableTreeNode(et);
for (EventOrigin eo: EventOrigin.getValues(et)) {
eos.add(new DefaultMutableTreeNode(new EventHazard(et, eo)));
}
event.add(eos);
}
add(event);
DefaultMutableTreeNode origin = new DefaultMutableTreeNode("Origin");
for (OriginType ot: OriginType.values()) {
DefaultMutableTreeNode oos = new DefaultMutableTreeNode(ot);
for (OriginOrigin oo: OriginOrigin.getValues(ot)) {
DefaultMutableTreeNode oon = new DefaultMutableTreeNode(oo);
for (OriginConsequence oc: OriginConsequence.getValues(ot, oo)) {
oon.add(new DefaultMutableTreeNode(new OriginHazard(ot, oo, oc)));
}
oos.add(oon);
}
origin.add(oos);;
}
add(origin);
DefaultMutableTreeNode task = new DefaultMutableTreeNode("Task");
for (TaskType tt: TaskType.values()) {
DefaultMutableTreeNode tts = new DefaultMutableTreeNode(tt);
for (TaskOrigin to: TaskOrigin.getValues(tt)) {
tts.add(new DefaultMutableTreeNode(new TaskHazard(tt, to)));
}
task.add(tts);
}
add(task);
}
}
);当我试图序列化对象时，它会打印这个堆栈；

at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)因为所有对象都是Serializable，所以我能做的唯一的事情就是引起这种情况，如下所示；
zone.setModel((DefaultTreeModel)tree.getModel());这一行从TreeModel中获取JTree，并将其转换为DefaultTreeModel，然后将其作为DefaultTreeModel放入zone对象中。我正在尝试序列化zone。
请让我知道我是否应该包括更多的代码，并从哪里。
任何帮助都是受欢迎的，特别是如果有更好的方法来获得堆栈跟踪。
编辑:按照建议，我现在正在使用JDK，并且已经更新了post中的堆栈，以包括以下内容

堆栈跟踪清楚地指出树中有一个不可序列化的类：com.cogentautomation.view.ViewMain$23。您必须这样读这个路径：com.cogentautomation.view.ViewMain是外部类，$23表示第23个匿名内部类。由于ViewMain中有很多匿名类，您可能很难弄清楚它是哪一个类。
最简单的方法是安装JDK (获取“java”的源代码)并设置一个异常断点at java.io.ObjectOutputStream.writeObject0(Unknown Source)。
顺便说一句，这种GUI将使你今后的生活变得困难。正如您所看到的，一个文件中大量匿名类的调试更加困难，而且文件长度一定很长。我建议您应用一些技术来瘦身ViewMain，如命令模式或指挥链。还有更多，也许你花一些时间在维基百科上了解他们。
