推荐答案
当您从实现的类派生时出现此警告序列化。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）来抑制此警告，或者为类提供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).
有一个这里的SO更好。
There is a discussion here on SO on which is preferable.
