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.Workflow (and that defined by superclass):
- Render request is received by the controller
- call to
handleRenderRequestInternalwhich just returns the view, named by the configuration propertyviewName.
This 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) - Since:
