public class ParameterizableViewController
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.
Workflow
(and that defined by superclass):
handleRenderRequestInternal which
just returns the view, named by the configuration property
viewName. Nothing more, nothing lessThis controller does not handle action requests.
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) |
