    Answer your question! Since we are embedding one page into another, we need to pass the same attribute to another page. We also added the attributes adduser.html to getAlluser.html These attributes are model.addAttribute ("user", new User ());

     @Controller

    @RequestMapping (value = "/ admin") public class AdminController {

     @Autowired private UserService userService; @RequestMapping public String getAllUser(Model model){ model.addAttribute("getAllUser", this.userService.getAllUser()); model.addAttribute("user", new User()); //Добавил эту строчку return "getAlluser"; } @RequestMapping(value = "/add", method = RequestMethod.GET) public String getAddPageUser(Model model){ model.addAttribute("user", new User()); return "adduser"; } @RequestMapping(value = "/add", method = RequestMethod.POST) public String addUser(@ModelAttribute("user") User user){ userService.addUser(user); return "redirect:/admin";
