When I used Eclipse it had a nice feature to generate serial version UID.
But what to do in IntelliJ?
How to choose or generate identical serial version UID in IntelliJ?
And what to do when you modify old class?
If you haven't specify the id, it is generated at runtime...
回答1:
Without any plugins:
You just need to enable highlight: (Idea v.2016, 2017 and 2018, previous versions may have same or similar settings)
File -> Settings -> Editor -> Inspections -> Java -> Serialization issues -> Serializable class without 'serialVersionUID' - set flag and click 'OK'. (For Macs, Settings is under IntelliJ IDEA -> Preferences...)
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.
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.
回答2:
Install GenerateSerialVersionUID plugin
回答3:
Easiest method: Alt+Enter on
private static final long serialVersionUID = ;
IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on 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.
回答4:
IntelliJ IDEA Plugins / GenerateSerialVersionUID https://plugins.jetbrains.com/plugin/?idea&id=185
very nice, very easy to install. you can install that from plugins menu, select install from disk, select the jar file you unpacked in the lib folder. restart, control + ins, and it pops up to generate serial UID from menu. love it. :-)
回答5:
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.
