Я пытаюсь войти в систему, используя jstl taglib.Ниже приведен код моей части контроллера
@SuppressWarnings("unused")
@RequestMapping(value = "/authentication", method = RequestMethod.POST)
public String login(@ModelAttribute("mstUsermaster")MstUsermaster mstUsermaster, BindingResult bindingResult, Model model) {
MstUsermaster usermaster=loginService.authenticateUser(mstUsermaster);
if(mstUsermaster != null ){
System.out.println("You Are a Valid User "+mstUsermaster.getName());
model.addAttribute("mstUsermaster1",usermaster);
}else{
model.addAttribute("loginMessage", "You have entered Wrong UserName or Password!");
return "index";
}
return "dashboard";
}
jsp страница (соответствующая часть)
