Class DelegatingTilesRequestProcessor

java.lang.Object
  TilesRequestProcessor
      org.springframework.web.struts.DelegatingTilesRequestProcessor

Deprecated. as of Spring 3.0

@Deprecated
public class DelegatingTilesRequestProcessor
extends TilesRequestProcessor

Subclass of Struts's TilesRequestProcessor that autowires Struts Actions defined in ContextLoaderPlugIn's WebApplicationContext (or, as a fallback, in the root WebApplicationContext).

Behaves like DelegatingRequestProcessor, but also provides the Tiles functionality of the original TilesRequestProcessor. As there's just a single central class to customize in Struts, we have to provide another subclass here, covering both the Tiles and the Spring delegation aspect.

The default implementation delegates to the DelegatingActionUtils class as fas as possible, to reuse as much code as possible despite the need to provide two RequestProcessor subclasses. If you need to subclass yet another RequestProcessor, take this class as a template, delegating to DelegatingActionUtils just like it.

Method Detail

init

public void init(ActionServlet actionServlet,
                 ModuleConfig moduleConfig)
          throws ServletException

Deprecated.

Throws:

ServletException

initWebApplicationContext

protected WebApplicationContext initWebApplicationContext(ActionServlet actionServlet,
                                                          ModuleConfig moduleConfig)
                                                   throws java.lang.IllegalStateException

Deprecated.

Fetch ContextLoaderPlugIn's WebApplicationContext from the ServletContext, falling back to the root WebApplicationContext. This context is supposed to contain the Struts Action beans to delegate to.

Parameters:

actionServlet - the associated ActionServlet

moduleConfig - the associated ModuleConfig

Returns:

the WebApplicationContext

Throws:

java.lang.IllegalStateException - if no WebApplicationContext could be found

getWebApplicationContext

protected final WebApplicationContext getWebApplicationContext()

Deprecated.

Return the WebApplicationContext that this processor delegates to.

processActionCreate

protected Action processActionCreate(HttpServletRequest request,
                                     HttpServletResponse response,
                                     ActionMapping mapping)
                              throws java.io.IOException

Deprecated.

Override the base class method to return the delegate action.

Throws:

java.io.IOException

getDelegateAction(ActionMapping)

getDelegateAction

protected Action getDelegateAction(ActionMapping mapping)
                            throws BeansException

Deprecated.

Return the delegate Action for the given mapping.

The default implementation determines a bean name from the given ActionMapping and looks up the corresponding bean in the WebApplicationContext.

Parameters:

mapping - the Struts ActionMapping

Returns:

the delegate Action, or null if none found

Throws:

BeansException - if thrown by WebApplicationContext methods

See Also:

determineActionBeanName(ActionMapping)

determineActionBeanName

protected java.lang.String determineActionBeanName(ActionMapping mapping)

Deprecated.

Determine the name of the Action bean, to be looked up in the WebApplicationContext.

The default implementation takes the mapping path and prepends the module prefix, if any.

Parameters:

mapping - the Struts ActionMapping

Returns:

the name of the Action bean
