The jsp file under the maven:web project folder created by idea cannot be accessed

problem description

create a jsp folder under webapp to store jsp pages. Submission via form cannot be located. 404 is returned.

the environmental background of the problems and what methods you have tried

when writing Filter, I found that both css and js were dropped by Filter. Baidu found a way to put the jsp page into a separate folder, and the annotated urlPattern= "jsp/*" could solve the problem, but in practice, I found that it was impossible to locate jsp after putting it into a separate folder, no matter how to change the address of action.
