just in case, if it needed - build.gradle:

Answer 1

In your controller, uncomment the #requestMapping annotation and set the value like this:
#RequestMapping(value="/personform")
Your view resolver cannot find a correct mapping without the above #requestMapping annotation.
Note that jsp page under WEB-INF directory cannot be directly accessed by typing the uri in the browser, you have to use controller or servlet (in your case it is controller) to access it.
