How to provide support for URLs with .jsp extension in spring

I have been told in this post that it is possible to have .jsp extension in URL structure using Spring. I have been trying to achieve it with the following code:

HelloController.java

@Controller
@RequestMapping("/welcome")
public class HelloController {
    @RequestMapping(value="/item.jsp", method = RequestMethod.GET)
    public String helloDotJSP(ModelMap model) {

        System.out.println("/item.jsp RequestMapping");
        model.addAttribute("message", "Spring 3 MVC Hello World");
        return "item";
    }
}

And when I try to access the page localhost:8080/app/welcome/item.jsp I get the error that The requested resource is not available. But when I try to just modify the extension from /item.jsp to for example /item.other it starts working. How can I add support for .jsp extension?

Thank you for your help.

You are getting the "requested resource is not available" because I your servlet mapping in the web.xml is not mapping item.jsp to the Spring DispatcherServlet.

Regardless, if your requirement is just to support old URLs, there are more effective ways of doing it.

Most lo-fi is to create jsps that with the same name and structure as the old urls, and in each of these jsps add scriptlets like 

<%
response.setStatus(301);
response.setHeader( "Location", "/new-url.htm" );
response.setHeader( "Connection", "close" );
%>

I don't usually recommend scriptlets but in cases like these, its the simplest solution.

You can also add 301 redirect rules if you have a fronting webserver like apache.

Hope this helps.
