jsp-4 用cookie实现记住密码
这次就有点简单了
基本是jsp-3的代码但是有些修改
public void login(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
User user=new User();
String username=req.getParameter("username");
user.setUsername(username);
String password=req.getParameter("password");
user.setPassword(password);
User use=userServive.login(user);
if(use!=null){
String [] ischeck=req.getParameterValues("ischeck");
if(ischeck!=null&&"true".equals(ischeck[0])){
//添加cookie信息
Cookie usernameCookie=new Cookie("username", username);
Cookie passwordCookie=new Cookie("password",password );
usernameCookie.setMaxAge(60*60*24*1);//一天
passwordCookie.setMaxAge(60*60*24*1);
resp.addCookie(usernameCookie);
resp.addCookie(passwordCookie);
}
resp.sendRedirect("loginSuccess.jsp");
}else{
resp.sendRedirect("loginFail.jsp");
}
}

//取出Cookie

for(int i=0;i<cookie.length;i++){
if(cookie[i].getName().equals("username")){
username=cookie[i].getValue();
}
if(cookie[i].getName().equals("password")){
password=cookie[i].getValue();
}

我就在纠结的是根据mvc的原则，cookie的操作是不是放在jsp？
