下面是使用cookie保存皮肤的代码：
backbean：
@Scope(SESSION)@Name("skinBean")public class SkinBean {
private String skin = "blueSky";
public String getSkin() { HttpServletRequest httpServletRequest = (HttpServletRequest) FacesContext .getCurrentInstance().getExternalContext().getRequest(); Cookie[] cookies = httpServletRequest.getCookies(); if (cookies != null) { for (int i = 0; i < cookies.length; i++) { if (cookies[i].getName().equalsIgnoreCase("skin")) { this.skin = cookies[i].getValue();
break;//只取得最后选择的皮肤 } } } return skin; }
public void setSkin(String skin) { this.skin = skin; HttpServletResponse httpServletResponse = (HttpServletResponse) FacesContext .getCurrentInstance().getExternalContext().getResponse(); Cookie cookie = new Cookie("skin", skin); cookie.setMaxAge(365); cookie.setComment("Richfaces skin"); httpServletResponse.addCookie(cookie); } public void skinChangeListener(ActionEvent event){ //HtmlSelectOneMenu ss = (HtmlSelectOneMenu) event.getComponent().findComponent("selectSkin"); //String selected=ss.getValue().toString(); //this.skin=selected; }
skin.xhtml
<h:selectOneMenu id="selectSkin" value="#{skinBean.skin}"> <f:selectItem itemLabel="Wfw" itemValue="WfwSkin" /> <f:selectItem itemLabel="Plain" itemValue="plain" /> <f:selectItem itemLabel="EmeraldTown" itemValue="emeraldTown" /> <f:selectItem itemLabel="BlueSky" itemValue="blueSky" /> <f:selectItem itemLabel="Wine" itemValue="wine" /> <f:selectItem itemLabel="JapanCherry" itemValue="japanCherry" /> <f:selectItem itemLabel="Ruby" itemValue="ruby" /> <f:selectItem itemLabel="Classic" itemValue="classic" /> <f:selectItem itemLabel="DeepMarine" itemValue="deepMarine" /> <a4j:support event="onchange" limitToList="true" actionListener="#{skinBean.skinChangeListener}" oncomplete="
window.location.href=window.location.href;
//window.location.reload(true);" reRender="selectSkin" ajaxSingle="true"> </a4j:support> </h:selectOneMenu>
注意：因为request和response不同步的原因，所以必须让页面刷新一次
