Annotation Help

[sgentry]

I have a controller which has a few actions, which are triggered by hitting various buttons on the page. I would like to have a default action, but am unsure how to annotate the method. Here is an example:

@Controller
@RequestMapping("/view.jsp")
public class ExampleController {

    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView displayResults() {
        ModelAndView mav = new ModelAndView("view");
        mav.addObject("queryResults", methodToQueryDBForListing());
        return mav;
    }

    @RequestMapping(method = RequestMethod.POST, params="submit=Action 1")
    public ModelAndView action1(@RequestParam("selectedItemKey") String key) {
        ModelAndView mav = new ModelAndView("action1");
        //Business logic
        return mav;
    }

    @RequestMapping(method = RequestMethod.POST, params="submit=Action 2")
    public ModelAndView action2(@RequestParam("selectedItemKey") String key) {
        ModelAndView mav = new ModelAndView("action2");
        //Business logic
        return mav;
    }
  
    //A few more methods which basically do what action1 and action2 do
}

How can I annotate a method which will act on a POST with any submit button pressed with no key selected?

I have tried:

@RequestMethod(method = RequestMethod.POST, params="!selectedItemKey")
@RequestMethod(method = RequestMethod.POST)

I'd really hate it if I had to set required = false on each of the methods which take RequestParams and then conditionally check to see if one comes in or not... Is there a way to annotate this to work properly?

@RequestMapping(method = RequestMethod.POST, params= {"!selectedItemKey" , "submit"})

It seems odd though, that the method with just "!selectedItemKey" wasn't selected after the other candidates were disallowed due to the required param not existing.

Perhaps I should file a bug.
