Dynamically changing the @ResponseStatus in annotation driven Spring MVC

Question

I am really not sure if this is feasible using Spring 3.2 MVC.

My Controller has a method declared as below:

@RequestMapping(method = RequestMethod.GET)

You cannot set multiple status value for @ResponseStatus. One approach I can think of is to use @ExceptionHandler for response status which is not HttpStatus.OK

@RequestMapping(value =  "login.htm", method = RequestMethod.POST)
@ResponseStatus(HttpStatus.OK)
public ModelAndView login(@ModelAttribute Login login) {
    if(loginIsValidCondition) {
        //process login
        //.....
        return new ModelAndView(...);
    }
    else{
        throw new InvalidLoginException();
    }
}

@ExceptionHandler(InvalidLoginException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ModelAndView invalidLogin() {
    //handle invalid login  
    //.....
    return new ModelAndView(...);
}
