/**
* Adapter to use the Portlet interface with the generic DispatcherPortlet.
* Calls the Portlet's render and processAction
* methods to handle a request.
*
* This adapter is not activated by default; it needs to be defined as a
* bean in the DispatcherPortlet context. It will automatically apply to
* mapped handler beans that implement the Portlet interface then.
*
*
Note that Portlet instances defined as bean will not receive initialization
* and destruction callbacks, unless a special post-processor such as
* SimplePortletPostProcessor is defined in the DispatcherPortlet context.
*
*
Alternatively, consider wrapping a Portlet with Spring's
* PortletWrappingController. This is particularly appropriate for
* existing Portlet classes, allowing to specify Portlet initialization
* parameters, etc.
