title: Spring MVC isFormSubmission() equivalent for annotations?
body: <p>With Spring MVC, it's easy to express a concept like "A user is submitting the form if they use POST or if they include the 'isSubmit' parameter."  You'd just extend <code>SimpleFormController</code> and override the <code>isFormSubmission</code> method.</p>
  
  <p>However, Spring MVC now uses these neat annotations like <code>@RequestMapping</code> to handle requests.  <code>@RequestMapping</code> has an obvious filter for whether somebody used a GET or a POST, but I don't see any inherent support for all of the useful logic SimpleFormController provided.  Is it still available to me with annotations?</p>
