Class DelegatingPhaseListenerMulticaster

java.lang.Object
  org.springframework.web.jsf.DelegatingPhaseListenerMulticaster

All Implemented Interfaces:: Serializable, EventListener, javax.faces.event.PhaseListener

public class DelegatingPhaseListenerMulticaster
extends Object
implements javax.faces.event.PhaseListener
extends Object
implements javax.faces.event.PhaseListener

JSF PhaseListener implementation that delegates to one or more Spring-managed PhaseListener beans coming from the Spring root WebApplicationContext.

Configure this listener multicaster in your faces-config.xml file as follows:

 <application>
   ...
   <phase-listener>
     org.springframework.web.jsf.DelegatingPhaseListenerMulticaster
   </phase-listener>
   ...
 </application>

The multicaster will delegate all beforePhase and afterPhase events to all target PhaseListener beans. By default, those will simply be obtained by type: All beans in the Spring root WebApplicationContext that implement the PhaseListener interface will be fetched and invoked.

Note this multicaster's getPhaseId() method will always return ANY_PHASE. The phase id exposed by the target listener beans will be ignored; all events will be propagated to all listeners.

This multicaster may be subclassed to change the strategy used to obtain the listener beans, or to change the strategy used to access the ApplicationContext (normally obtained via FacesContextUtils.getWebApplicationContext(FacesContext)).
