1.这个一个页面模拟的cookie，如果你要实现登录，当用户输入用户名密码时，到控制层用Cookie user = new Cookie("user",name+"-"+passward);加到cookie中，然后在访问此登录页面时，就先调用Cookie[] cookies=request.getCookies(); 看cookie中是否有user这个值，如果有就取得用户名、密码。代码示例：<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%String name="nihao";String passward="nihao";try{Cookie user = new Cookie("user",name+"-"+passward);user.setMaxAge(60);response.addCookie(user);Cookie[] cookies=request.getCookies();if(cookies!=null){for(int i=0;i<cookies.length;i++){if(cookies[i].getName().equals("user")){name=cookies[i].getValue().split("-")[0];passward=cookies[i].getValue().split("-")[1];request.setAttribute("name",name);request.setAttribute("pass",passward);}}}}catch(Exception e){e.printStackTrace();}%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title></title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--></head><body><form action="test10.jsp" method="post"><input type="text" value="${name}" name=name /></br><input type="text" value="${pass}" name=pass /><input type="submit" value="提交"></form></body></html>
