In Eclipse, I can press Alt+Shift+J and get a javadoc comment automatically generated with fields, returns, or whatever would be applicable for that specific javadoc comment. I'm assuming that IntelliJ IDEA has this feature. Can anyone tell me if there is a keyboard shortcut for this?
回答1:
Typing /** + then pressing Enter above a method signature will create Javadoc stubs for you.
回答2:
You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else.
By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment in order to find the action.
回答3:
Shortcut Alt+Enter shows intention actions where you can choose "Add Javadoc".
