Project Directory Related – Collapse Empty Bundle

window reset
This is when you suddenly mess up the window, you can still restore it, just restore it directly, and it will be fine.

Quick completion semicolon
CTRL + SHIFT + ENTER can quickly generate a semicolon at the end anywhere in the current line
Quickly find Controller methods
If there are a lot of controllers in your project, there are a lot of http or resful methods in it. How to quickly find these methods? At this time, ctrl+alt+shift+n can come in handy.
For example, if you vaguely remember that there is a path of users in the interface related to login, then use ctrl+alt+shift+n and directly enter /users.
When you are looking for methods in thousands of Controllers, this trick can greatly improve efficiency.
brace matching
This is also very useful, because the code is too long, and a for loop may have filled the entire screen. At this time, it is very difficult to find the other side corresponding to a certain brace. You can position the cursor on one side of a brace, and then use ctrl+] or ctrl+[ to go back and forth.
Supplement: The above configuration information is saved in .idea under the user directory of the system disk
By default, there will be these two files
config: During the initial installation of IntelliJ IDEA, you are asked whether to import the existing configuration information. This config is your configuration information, which is convenient for reinstallation when changing computers and systems. The premise is to save this folder.
system: This folder is when an unpredictable error occurs in IntelliJ IDEA, such as a blue screen, a sudden power failure and the project cannot be started, you can try to delete this file and let the system regenerate a system file
