I am receiving the following error trying to run a Spring MVC program.

org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/spring-mvc-demo/] in DispatcherServlet with name 'dispatcher'


package com.luv2code.springdemo.mvc;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

@RequestMapping("/")
public String showPage() {

return "main-menu";
}

}
