    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.

Workflow (and that defined by superclass):

1. Request is received by the controller
2. call to `handleRequestInternal` which just returns the view, named by the configuration property `viewName`. Nothing more, nothing less

Exposed configuration properties (and those defined by superclass):

name | default | description
viewName | null | the name of the view the viewResolver will use to forward to (if this property is not set, an exception will be thrown during initialization)
