I'm using Spring 3, and trying to set up a simple web-app using annotations to define controller mappings. This seems to be incredibly difficult without peppering all the urls with *.form or *.do

Because part of the site needs to be password protected, these urls are all under /secure. There is a <security-constraint> in the web.xml protecting everything under that root. I want to map all the Spring controllers to /secure/app/.

Example URLs would be:
each of which I would handle with an appropriate jsp/xml/whatever.

So, in web.xml I have this:



And in despatcher-servlet.xml I have this:

 <context:component-scan base-package="controller" />

In the Controller package I have a controller class:

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;

public class HomePageController {
    public HomePageController() { }

    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView getPage(HttpServletRequest request)
        ModelAndView mav = new ModelAndView();
        return mav;

Under /WEB-INF/jsp I have a "main.jsp", and a suitable view resolver set up to point to this. I had things working when mapping the despatcher using *.form, but can't get anything working using the above code.

When Spring starts up it appears to map everything correctly:

13:22:36,762 INFO main annotation.DefaultAnnotationHandlerMapping:399 - Mapped URL path [/secure/app/main] onto handler [controller.HomePageController@2a8ab08f]

I also noticed this line, which looked suspicious:

13:25:49,578 DEBUG main servlet.DispatcherServlet:443 - No HandlerMappings found in servlet 'dispatcher': using default

And at run time any attempt to view /secure/app/main just returns a 404 error in Tomcat, with this log output:

13:25:53,382 DEBUG http-8080-1 servlet.DispatcherServlet:842 - DispatcherServlet with name 'dispatcher' determining Last-Modified value for [/secure/app/main]
13:25:53,383 DEBUG http-8080-1 servlet.DispatcherServlet:850 - No handler found in getLastModified
13:25:53,390 DEBUG http-8080-1 servlet.DispatcherServlet:690 - DispatcherServlet with name 'dispatcher' processing GET request for [/secure/app/main]
13:25:53,393 WARN http-8080-1 servlet.PageNotFound:962 - No mapping found for HTTP request with URI [/secure/app/main] in DispatcherServlet with name 'dispatcher'
13:25:53,393 DEBUG http-8080-1 servlet.DispatcherServlet:677 - Successfully completed request

So... Spring maps a URL, and then "forgets" about that mapping a second later? What is going on?
