public class ParameterizableViewController extends AbstractController
Trivial controller that always returns a named view. The view can be configured using an exposed configuration property. This controller offers an alternative to sending a request straight to a view such as a JSP. The advantage here is that the client is not exposed to the concrete view technology but rather just to the controller URL; the concrete view will be determined by the ViewResolver.
An alternative to the ParameterizableViewController is a
MultiActionController,
which can define a variety of handler methods that just return a plain
ModelAndView instance for a given view name.

handleRequestInternal which
just returns the view, named by the configuration property
