You aren't sending anything. You need either a form or some sort of adding parameters to your URL or javascript to send a request. You are just clicking a link which doesn't send anything — M. Deinum, Jun 02 '16 at 06:54
Unless you are using Ajax or passing a url query string it will not work — Scary Wombat, Jun 02 '16 at 06:54
try to surround your html inputs with a from and define the form's action: as written in your request mapping ("/delete"). Define the form's method as "get" while your java function does not specify the method, as default it will be get. Put a submit button in form offcourse — Ismail Sahin, Jun 02 '16 at 07:11
User form action to send the data to controller via JSP or JS or Jquery , Ajax etc.... — Pavan, Jun 02 '16 at 07:34

In order to send the Data from JSP to Controller

Create a form with action (/delete) and method=POST
Create a Controller with the @RequestMapping("/delete") that point to form action
Use Request.getParameter("name") in Controller.

Now on submit button in the JSP Spring Servlet Dispatcher will the mapping form in the Controller class and send the data to the controller from JSP.

Let us know if more inforamtion needed I will share the sample example
