@Deprecated
public abstract class AbstractCommandController
extends BaseCommandController

Abstract base class for custom command controllers. Autopopulates a command bean from the request. For command validation, a validator (property inherited from BaseCommandController) can be used.

This command controller should preferrable not be used to handle form submission, because functionality for forms is more offered in more detail by the AbstractFormController and its corresponding implementations.

Exposed configuration properties (and those defined by superclass):
none (so only those available in superclass).

Workflow (and that defined by superclass):

2.0

Constructor Detail

AbstractCommandController

public AbstractCommandController()

Deprecated.

Create a new AbstractCommandController.

AbstractCommandController

public AbstractCommandController(Class commandClass)

Deprecated.

Create a new AbstractCommandController.

Parameters:

commandClass - class of the command bean

AbstractCommandController

public AbstractCommandController(Class commandClass,
                         String commandName)

Method Detail

handleActionRequestInternal

protected final void handleActionRequestInternal(ActionRequest request,
                               ActionResponse response)
                                          throws Exception

Deprecated.

Description copied from class: AbstractController

Subclasses are meant to override this method if the controller is expected to handle action requests. The contract is the same as for handleActionRequest.

The default implementation throws a PortletException.

Overrides:

handleActionRequestInternal in class AbstractController

Throws:

Exception

See Also:

AbstractController.handleActionRequest(javax.portlet.ActionRequest, javax.portlet.ActionResponse), AbstractController.handleRenderRequestInternal(javax.portlet.RenderRequest, javax.portlet.RenderResponse)

handleRenderRequestInternal

protected final ModelAndView handleRenderRequestInternal(RenderRequest request,
                                       RenderResponse response)
                                                  throws Exception

Deprecated.

Deprecated.

Template method for request handling, providing a populated and validated instance of the command class, and an Errors object containing binding and validation errors.

Call errors.getModel() to populate the ModelAndView model with the command and the Errors instance, under the specified command name, as expected by the "spring:bind" tag.

Parameters:

request - current action request

response - current action response

command - the populated command object

errors - validation errors holder

Throws:

Exception

See Also:

Errors, BindException.getModel()
