@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.

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):
