Phase Listener

        

JSF life-cycle includes six phases and phase events are fired during the start and end of each phase. We can capture phase events by defining a Phase Listener class as below. The class should implement PhaseListener interface. You can implement beforePhase() and afterPhase() methods according to the your need.

package roseindia.phaselistener;

import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;

public class CustomPhaseListener implements PhaseListener{ 
   public CustomPhaseListener() { }

   public void afterPhase(PhaseEvent event) {
   System.out.println("After Phase: " + event.getPhaseId());
   }

   public void beforePhase(PhaseEvent event) {
   System.out.println("Before Phase: " + event.getPhaseId());
   }

   public PhaseId getPhaseId() {
  return PhaseId.ANY_PHASE;
   }
}
