Spring MVC: HTTP Status 404, No mapping found for HTTP request with URI [/BugzillaReport/] in DispatcherServlet with name 'spring-dispatcher'

Questions:

I am struggling to bring up my application. But i am getting the HTTP status 404 with console warning as “WARNING: No mapping found for HTTP request with URI [/BugzillaReport/] in DispatcherServlet with name ‘spring-dispatcher'”

I check many people answers, but still, I am not able to fix this. Please lend your hands.

About the application: to upload an xml, and create another xml in the backend and give an option for the user to download new XML. (application is not complete though)

below are the contents of all my files:

web.xml

    </servlet>
