title: Spring MVC controller HTTP GET query parameters
body: <p><strong>How do I, without annotations, create and wire a controller that will perform an action based on a query parameter?</strong> </p>
  
  <p>So maybe I've got a page with a list of items on it, and each one is a link like "edititem.htm?id=5".  When the user clicks a link I want the controller to load up "item #5" and pass it to my edit form.</p>
  
  <p>I'm sorry to ask such a silly question, but for some reason I can't find any example of doing this online.</p>
