java怎么用cookie写购物车

Answer 1

处理cookie思路。。
//以用户的用户名和密码创建cokie
Cookie nameCookie=new Cookie("name",java.net.URLEncoder.encode(name.trim(),"utf-8"));
Cookie  passwordCookie=new Cookie("password",java.net.URLEncoder.encode(password.trim(),"utf-8"));
//设置cookie的实效时间
nameCookie.setMaxAge(7*24*60*60);
passwordCookie.setMaxAge(7*24*60*60);
//设置Cookie的父路径
nameCookie.setPath(request.getContextPath()+"/");
passwordCookie.setPath(request.getContextPath()+"/");
//放入Cookie到响应头 
HttpServletResponse response=ServletActionContext.getResponse();
response.addCookie(nameCookie);
response.addCookie(passwordCookie);
