public abstract class AbstractCommandController
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.
In most cases this command controller should not be used to handle form
submission, because functionality for forms is 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):
BaseCommandController.setCommandClass(java.lang.Class)
,
BaseCommandController.setCommandName(java.lang.String)
,
BaseCommandController.setValidator(org.springframework.validation.Validator)
