And what to do when you modify old class?

Without any plugins:
没有任何插件：
You just need to enable highlight: (Idea v.2016, 2017 and 2018, previous versions may have same or similar settings)
您只需要启用高亮：（Idea v.2016、2017和2018，之前的版本可能有相同或相似的设置）
File -> Settings -> Editor -> Inspections -> Java -> Serialization issues -> Serializable class without 'serialVersionUID' - set flag and click 'OK'. (For Macs, Settings is under IntelliJ IDEA -> Preferences...)
文件 -> 设置 -> 编辑器 -> 检查 -> Java -> 序列化问题 -> 没有“serialVersionUID”的可序列化类 - 设置标志并单击“确定”。（对于 Mac，设置位于 IntelliJ IDEA -> 首选项...）
Now, if your class implements Serializable, you will see highlight and alt+Enter on class name will propose to generate private static final long serialVersionUID.
现在，如果您的类实现了Serializable，您将看到突出显示，并且类名上的 alt+Enter 将建议生成private static final long serialVersionUID.
UPD: a faster way to find this setting - you might use hotkey Ctrl+Shift+A(find action), type Serializable class without 'serialVersionUID'- the first is the one.
UPD：找到此设置的更快方法 - 您可以使用热键Ctrl+Shift+A（查找操作），输入Serializable class without 'serialVersionUID'- 第一个是。

with in the code editor, Open the class you want to create the UID for , Right click -> Generate -> SerialVersionUID. You may need to have the GenerateSerialVersionUID plugin installed for this to work.
在代码编辑器中，打开要为其创建 UID 的类，右键单击 -> 生成 -> SerialVersionUID。您可能需要安装 GenerateSerialVersionUID 插件才能使其工作。

Easiest method: Alt+Enteron
最简单的方法：Alt+ Enteron
private static final long serialVersionUID = ;
IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter(Option+Enteron Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.
IntelliJ 将在=. 将光标放在上面并点击alt+ Enter（Mac 上的Option+ Enter）。你会得到一个弹出窗口，上面写着“随机更改 serialVersionUID 初始化程序”。只需按回车键，它就会用随机长度填充该空间。
