- org.springframework.web.portlet.handler.SimplePortletHandlerAdapter

All Implemented Interfaces:
Aware, PortletContextAware, HandlerAdapter
```
public class SimplePortletHandlerAdapter
extends Object
implements HandlerAdapter, PortletContextAware
```
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.

2.0

  - setPortletContext
```
public void setPortletContext(PortletContext portletContext)
```
    Description copied from interface: PortletContextAware
    Set the PortletContext that this object runs in.
    Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.
    Specified by:
    setPortletContext in interface PortletContextAware
    Parameters:
    portletContext - PortletContext object to be used by this object
  - supports
```
public boolean supports(Object handler)
```
    Description copied from interface: HandlerAdapter
    Given a handler instance, return whether or not this HandlerAdapter can support it. Typical HandlerAdapters will base the decision on the handler type. HandlerAdapters will usually only support one handler type each.
    A typical implementation:
    return (handler instanceof MyHandler);
    Specified by:
    supports in interface HandlerAdapter
    Parameters:
    handler - handler object to check
    Returns:
    whether or not this object can use the given handler
  - handleAction
```
public void handleAction(ActionRequest request,
                         ActionResponse response,
                         Object handler)
                  throws Exception
```
    Description copied from interface: HandlerAdapter
    Use the given handler to handle this action request. The workflow that is required may vary widely.
    Specified by:
    handleAction in interface HandlerAdapter
    Parameters:
    request - current action request
    response - current action response
    handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.
    Throws:
    Exception - in case of errors
    See Also:
    Portlet.processAction(javax.portlet.ActionRequest, javax.portlet.ActionResponse)
  - handleRender
```
public ModelAndView handleRender(RenderRequest request,
                                 RenderResponse response,
                                 Object handler)
                          throws Exception
```
    Description copied from interface: HandlerAdapter
    Use the given handler to handle this render request. The workflow that is required may vary widely.
    Specified by:
    handleRender in interface HandlerAdapter
    Parameters:
    request - current render request
    response - current render response
    handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.
    Returns:
    ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly
    Throws:
    Exception - in case of errors

    Portlet.render(javax.portlet.RenderRequest, javax.portlet.RenderResponse)
  - handleResource
```
public ModelAndView handleResource(ResourceRequest request,
                                   ResourceResponse response,
                                   Object handler)
                            throws Exception
```
    Description copied from interface: HandlerAdapter
    Use the given handler to handle this resource request. The workflow that is required may vary widely.
    Specified by:
    handleResource in interface HandlerAdapter
    Parameters:
    request - current render request
    response - current render response
    handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.
    Returns:
    ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly
    Throws:
    Exception - in case of errors

  - handleEvent
```
public void handleEvent(EventRequest request,
                        EventResponse response,
                        Object handler)
                 throws Exception
```
    Description copied from interface: HandlerAdapter

    Specified by:
    handleEvent in interface HandlerAdapter
    Parameters:
    request - current action request
    response - current action response
    handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.
