jsp file not recognized in controller class

Question

When I try to return my jsp view file I get yellow squiggly lines saying "Cannot resolve MVC view index". Ive tried moving the webapp folder to different locations but doesn't seem to matter. And obviously i get an error when trying to access the index jsp file when i '/action'. I get "Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Answer 1

If you are using a spring boot with JSP or thymeleaf or any other template engines you do not need to set anything.
You have to put your template files under this path src/main/resources/templates .
If you are not using any template engine then just put your HTML file under this path src/main/resources/static/ .
Also, I suggest that use thymeleaf instead of JSP .
