When the idea editor can't switch to Chinese, are you still using the cumbersome way of typing Chinese and then copying and pasting? This is actually unnecessary. One line of code can solve it: Next, go directly to the code.
Proceed as follows
(1) Find help->Edit Custom VM Options in the menu in idea, and click to enter.
(2) Type -Drecreate.x11.input.method=true in the Edit Custom VM Options opened in the first step
(3) Restart idea. (Remember to restart, otherwise it will not take effect!)
