推荐答案

当您从实现 Serializable 的类派生时，会出现此警告.在您的情况下，Serializable 父类是 JFrame.

This warning comes when you derive from a class that implements Serializable. In your case, the Serializable parent class is JFrame.

您可以使用@SuppressWarnings("serial") 取消此警告，或为该类提供一个serialVersionUID:private static final long serialVersionUID = ...;(点的长值).

You can suppress this warning with @SuppressWarnings("serial"), or give the class a serialVersionUID: private static final long serialVersionUID = ...; (with a long value for the dots).

这里有一个关于 SO 的讨论，这是更可取的.

There is a discussion here on SO on which is preferable.
