自定义JSF PhaseListener监听器

自定义JSF PhaseListener，需要实现javax.faces.event.PhaseListener.PhaseListener接口,页面使用可以直接用标签：

<f:phaseListener
   type="org.web.jsf.listener.RegistEditableValueChangePhaseListener">
  </f:phaseListener>



org.web.jsf.listener.RegistEditableValueChangePhaseListener为我的监听类

主要代码如下：

package org.iata.seurat.web.jsf.listener;

import java.util.Iterator;

import javax.faces.component.EditableValueHolder;
import javax.faces.component.UIComponent;
import javax.faces.component.UIInput;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;


/**
 * Regist the Editable Value Changed.
 * 
 * @author Xiao Jianbo, 2012-10-17
 */
public class RegistEditableValueChangePhaseListener implements PhaseListener {

    private static final long serialVersionUID = 1L;

    /**
     * process after phase event.
     * 
     * @param event - Phase Event
     */
    @Override
    public void afterPhase(PhaseEvent event) {
        FacesContext context = event.getFacesContext();
        boolean postback = context.getRenderKit().getResponseStateManager().isPostback(context);
        if (!postback) {
        }
    }


    @Override
    public void beforePhase(PhaseEvent event) {

    }

    @Override
    public PhaseId getPhaseId() {
        return PhaseId.RENDER_RESPONSE;
    }

 }
