PathVariable does not work at all

Question

For some reason, my @PathVariable annotation is not working at all, after doing some Google search I've not been able to find anyone else with the same issue, this is the code:

@Controller
@RequestMapping("/bot")
public class BotController {
    @RequestMapping(value = "/test", method = RequestMethod.GET)
    public void test() {
        System.out.println("test");
        Store.INSTANCE.getChatBot().postMessage("test");
    }

    @RequestMapping(value = "/say/{text}", method = RequestMethod.GET)
    public void say(final @PathVariable("text") String text) {
        System.out.println("say: " + text);
        Store.INSTANCE.getChatBot().postMessage(text);
    }
}

This works: http://localhost:8080/GithubHookSEChatService/bot/test

This does not work: http://localhost:8080/GithubHookSEChatService/bot/say/realtest

Apart from that the System.out.println("say: " + text) does not happen, the only other clue I have is:

24-Aug-2014 17:25:21.611 WARNING [http-apr-8080-exec-24] 
org.springframework.web.servlet.PageNotFound.noHandlerFound 
No mapping found for HTTP request with URI 
[/GithubHookSEChatService/bot/say/realtest] in DispatcherServlet with name 'dispatcher'

I'm running out of clues, does anyone know what is happening? Why doesn't the latter work?

My relevant web.xml:

This issue appears to not be related to @PathVariable only, it actually also fails on:

@RequestMapping(value = "/test/test", method = RequestMethod.GET)
@ResponseBody
public void test() {
    System.out.println("test");
    Store.INSTANCE.getChatBot().postMessage("test");
}

This happens because there are multiple levels of subpaths, I found the solution of my issue in In Spring MVC, how can I map nested URLs such as /settings/, /settings/users/, and /settings/users/delete?

The only thing you need to do, is to include the following in your dispatcher-servlet.xml:

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>

And then everything works as expected!
