此后还有更多，但这显然是最相关的，如果需要我可以添加更多的错误甚至更具体的代码，但我已经明白了我已经放弃了解决这个问题。我无法弄清楚如何。我之前尝试过它可以工作的另一个框架，但是这个框架没有。

答案 0 :(得分：0)
一般来说，Swing和AWT对象不是Serializable。除了不尝试保存包含对这些对象之一的引用的任何内容之外，您无法做到这一点。一种方法是更改包含对transient的引用的字段。
在这种情况下，您显然正在尝试序列化Item个对象的列表。这不是标准的Java SE类，所以我猜测它是一个直接或间接包含对javax.swing.GroupLayout对象的引用的自定义类。
更新 - 显然不是。这导致我怀疑异常来自您未向我们展示的代码的另一部分。异常消息明确指出writeObject正在尝试序列化包含对javax.swing.GroupLayout对象的引用的内容。
（或许Item是在具有javax.swing.GroupLayout字段的类中声明的内部类？）
