使用cookie 记录登陆
public static final String Constants.COOKIE_REMEMBERME_KEY="user";
public class StringUtils{
public booblean isNotEmpty(String word){
if(wrod.equals("")){
return true;
}else{
return false;
}
}
/记录客户端Cookie中
if (StringUtils.isNotEmpty(rememberMe)) {
if (rememberMe.equals("true")) {
Cookie cookie = new Cookie(Constants.COOKIE_REMEMBERME_KEY, user.getUserName() + "==" + user.getPassword());
cookie.setMaxAge(60 * 60 * 24 * 14);
cookie.setPath("/");
response.addCookie(cookie);
}
}
User curUser = (User)session.getAttribute(Constants.USER);
if(curUser==null)
{
Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (Cookie cookie : cookies) {
if (Constants.COOKIE_REMEMBERME_KEY.equals(cookie.getName())) {
String value = cookie.getValue();
if (StringUtils.isNotBlank(value)) {
String[] split = value.split("==");
String userName = split[0];
String password = split[1];
try {
User user = userJdbc.getByUserName(userName);
if (null != user) {
if (user.getPassword().equalsIgnoreCase(password)) {
session.setAttribute(Constants.USER, user);
request.getSession().setAttribute("autoAuctionState", user.getAutoAuctionState());
}
}
} catch (Exception e) {
//response.sendRedirect("/index.ac");
}
} else {
//response.sendRedirect("/index.ac");
}
//response.sendRedirect("/index.ac");
}
}
}
}
// 客户端从本地查找服务器端发送过来的cookie,有没有user,如果有就把以下那个值负
<%
String userName = null;
String password = null;
Cookie[] cookies = request.getCookies();
for (int i = 0; cookies != null && i < cookies.length; i++) {
if(cookies[i].getName().equals("user")){

}
}
if(userName == null){

用户名：<input type="text" name="name" size="15" value="<%=userName %>" />
密码：<input type="password" name="pass" size="15" value="<%=password %>" />
记住密码：<input type="checkbox" name="ck" value="1"/>
