Answer 1

I think HttpSession is the right choice.
If you don't want to use HttpSession or any server storage such as Database, ... You can use this way - Client storage by using hidden inputs
Modify login to store studentdata in request attribute
#RequestMapping(value = "/login", method = RequestMethod.GET)
public static String login(HttpServletRequest request, final Model model) {
final Studentdata studentdata = new Studentdata();
studentdata.setName("username");
request.setAttribute("studentData", studentdata);
return "Login" ;
}
Modify login jsp
<form action="/loungeHotel/checkLogin" method="post">
<!-- Write all studentdata Properties as Hidden inputs -->
<input type="hidden" name="property1" value="${studentData.property1}"
<input type="hidden" name="property2" value="${studentData.property2}"
<input type="hidden" name="property3" value="${studentData.property3}"
<input type="submit" value="submit">
</form>
Modify checkLogin
RequestMapping(value = "/checkLogin", method = RequestMethod.POST)
public static String checkLogin(HttpServletRequest request, final Model model) {
System.out.println("here i want to access studentdata");
// Recreate StudentData From request.getParameter(...)
Studentdata studentdata = new Studentdata();
studentdata.setProperty1 ( request.getParameter("property1"));
// ... You may have to convert data too
return "MyAccount";
}
