title: optional POST parameter in spring MVC?
body: <p>I have the following code:</p>
  
  <pre><code>@RequestMapping(method = RequestMethod.POST)
  public ModelAndView editItem(String name, String description)
  </code></pre>
  
  <p>However, sometime description is not passed in (this is a simplified example than the real one), and i would like to make description optional, perhaps by filling in a default value if none is passed in. </p>
  
  <p>Anyone have any idea how to do that?</p>
  
  <p>thanks a lot!</p>
