action中生成cookie：
if (rememberMe != null) { // 創建Cookie
Cookie cokie_user = new Cookie("username", userName);
Cookie cokie_password = new Cookie("password", passWord);
cokie_user.setMaxAge(60 * 60); // 失效時間爲一小時
cokie_password.setMaxAge(60 * 60);
response.addCookie(cokie_user);
response.addCookie(cokie_password);
}
jsp中如此調用：
<%@ page language="java" contentType="text/html; charset=gb2312" pageEncoding="gb2312"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
<html:html locale="true">

Cookie[] cook=request.getCookies();
String userid="";
String password="";
if(cook!=null){
for(int i=0;i<cook.length;i++){
if(cook[i].getName().equals("username")){
userid=cook[i].getValue();
}
if(cook[i].getName().equals("password")){
password = cook[i].getValue();
}
}
}
