Spring MVC: Controller RequestMapping working, but return always gives a 404.Jsp Page not being loaded in spring

Question

While trying to access http://localhost:8080/student_tracker_2/student/edit/5 , my Spring is not redirecting me to add-student-form which would prepopulate the page based on the data in db. But it gives me a 404 error. The control is getting inside the controllers but not resolving the view. All the other controllers are working fine i.e add Student, remove and list all students. Get Student used in the edit part is also working fine.

The update-form and student-form are the same..so student form helps to add as well as update/edit student.

here are screenshots to understand the problem better:
list-students
adding a student
after clicking edit button

Error Message:-

HTTP Status 404 – Not Found

Type Status Report

Description: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Message: JSP file [/student/edit/WEB-INF/views/student-form.jsp] not found

UPDATE: I did miss a '/' in view resolver before WEB-INF as M.Denium pointing out. Thank you Sir.

did [this](https://stackoverflow.com/questions/39408610/spring-boot-jsp-file-as-view-not-loading-when-run-in-intellij) answer your question? — badger, Apr 11 '22 at 05:01
the solutions says that if its a jar type..jsps should not be in static resources. But i am using war type packing and also my jsps are in WEB-INF folder. Also I am not using spring-boot or intellij which was related to the other offered solutions. I am also adding my pom.xml file in case it helps present a clear description to my prblem. — Nainesh Goel, Apr 11 '22 at 07:51
Prefix of your view resolver is wrong. It needs an leading `/`. — M. Deinum, Apr 11 '22 at 12:35
