I am new to Spring MVC and i have some problems related to running the project with tomcat 10.1.16 (Ubuntu) on intellij idea, specifically as follows:

• If I create the index.jsp file in the WEB-INF folder, when running it only shows the content in the index.jsp file.
• If I delete the index.jsp and replace it in the MainController class with a RequestMapping to the home.jsp file, it immediately reports a 404 Not Found error.

This is my project structure:

And it works with just index.jsp file

and it gives error if i delete index.jsp

error

My Project: .git

I have tried many ways but can not run

I hope everyone can explain to me
