How to use ionic V6 in Spring MVC without CDN

I want to use .css/js files in resources directory in my Spring MVC app and use them in index.jsp. In V6 i am not getting any idea how to use it. I want to upgrade my app from V2.0.1 to V6.

If I were you, I would write this post in a different way.

Wha to do you need?
Help to upgrade your app or something else?
