The error I am facing

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.


Apache Tomcat/10.0.10

After giving the input the error shows up but the error shows. I have also tried other solutions available on stack overflow but none of them worked.I am using spring mvc 4 and used some youtube videos.

CodePudding user response：

Try by adding "/" in action attribute in html form

<form action="/add">
