Why doesn't spring mvc work?
I'm trying to learn spring mvc, but got stuck in the wall. For any requests, even the simplest ones, as in the screenshot below, I get a 404 error, the maximum that can be loaded is the Index in the root folder. When changing the prefix and moving the jsp to another folder, nothing happens either. I am trying to open helloworld.jsp
