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();
- }
