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):
handleRequestInternal
which
just returns the view, named by the configuration property
viewName
. Nothing more, nothing lessExposed 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, a null view name will be returned directing the caller to calculate the view name from the current request) |
