/**
 * <p>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.
 *
 * <p>An alternative to the ParameterizableViewController is a
 * {@link org.springframework.web.servlet.mvc.multiaction.MultiActionController MultiActionController},
 * which can define a variety of handler methods that just return a plain
 * ModelAndView instance for a given view name.
 *
 * <p>Workflow
 * (<a href="AbstractController.html#workflow">and that defined by superclass):
* <ol> * <li>Request is received by the controller * <li>call to {@link #handleRequestInternal handleRequestInternal} which * just returns the view, named by the configuration property * <code>viewName. Nothing more, nothing less * </ol> * </p> * * <p>Exposed configuration properties * (<a href="AbstractController.html#config">and those defined by superclass):
* <table border="1"> * <tr> * <td>name
