用cookie实现记住密码

1.jsp

<%String name="";String pwd="";Cookie[] cook=request.getCookies();if(cookie!=null){  for(int i=0;i<cook.length;i++)  {    if(cook[i].getName().equals("myCookieName"))    {        name=cook[i].getValue();     }    if(cook[i].getName().equals("myCookiePwd"))    {        pwd=cook[i].getValue();     }   } }%><form name="postion_login_from" action="UserServlet"  method="post">    <table>    <tr><td class="comm">用户名:</td>        <td><input type="text" name="pname" value="<%=name%>">        </td>    </tr>    <tr><td class="comm">密码:</td>        <td><input type="text" name="pwd" value="<%=pwd%>" >        </td>    </tr>    </table>    </form>

2.servlet

Cookie myCookieName=new Cookie("myCookieName",uname);                          myCookieName.setMaxAge(1*24*60*60);                         response.addCookie(myCookieName);Cookie myCookiePwd=new Cookie("myCookiePwd",upwd);                         myCookiePwd.setMaxAge(1*24*60*60);                      response.addCookie(myCookiePwd);

其中uname和upwd是你登录时从数据库中获取的用户名和密码。
