Answer 1

Change the controller method code to this one and check.

@RequestMapping(value = "/", method = RequestMethod.GET)
public String list(Model uiModel) {
  List<HotelAudit> contacts = HotelService.findAll();
  uiModel.addAttribute("contacts", contacts);
  return "list";
}

In general, I would advise you to study the basic information on working with the Spring Framework - there are some important points that can help at the initial stage.
Also, when developing views, I advise you to pay attention, for example, to the fact that Tags are included in JSP, this will allow you to noticeably utilize (fu word) the view code.
