Strongly recommend, don’t turn it off, don’t dislike trouble, his tips are all good for you, and help you improve your code quality, which is very helpful.

# Project Directory Related – Fold Empty Package< /strong>



#Window reset


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

# View local code history



# Quick completion semicolon


CTRL + SHIFT + ENTER anywhere on the current line to quickly generate a semicolon at the end.

# Quickly find the Controller method


If you have a lot of controllers in your project, there are a lot of http or resful method. How to quickly find these methods? At this time, ctrl+alt+shift+n can come in handy.

For example, you vaguely remember the interface related to billing, and there is a bill URL path , then use ctrl+alt+shift+n and directly enter /bill.

When you are looking for methods in thousands of Controllers, this trick can greatly improve efficiency.


# braces match


This is also very useful, because the code is too long, 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 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 reinstalling when changing computers and systems. The premise is to save this information. folder.

system: This folder is when IntelliJ IDEA encounters unpredictable errors, such as blue screens If the project cannot be started due to a sudden power failure, you can try to delete this file and let the system regenerate a system file.
