ParameterizableViewController (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版
org.springframework.web.servlet.mvc
Class ParameterizableViewController
java.lang.Object
org.springframework.context.support.ApplicationObjectSupport
org.springframework.web.context.support.WebApplicationObjectSupport
org.springframework.web.servlet.support.WebContentGenerator
org.springframework.web.servlet.mvc.AbstractController
org.springframework.web.servlet.mvc.ParameterizableViewController
- All Implemented Interfaces:
- ApplicationContextAware, ServletContextAware, Controller
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):
- Request is received by the controller
- 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) |
