当我试图保存产品并向我的保存产品控制器发出ajax请求时，我正在尝试制作一个购物应用程序控制器没有被调用，浏览器控制台上出现400（错误请求）错误。
主控制器代码：

@Controller
@RequestMapping("/")
public class MainController {
    private static final Logger logger = LogManager.getLogger(MainController.class.getName());

    public static String loginPage = "login/login";
    public static String signUpPage = "login/signUp";

    ProductService productServ;
    UserService userService;

    @RequestMapping("/")
    public String viewPage() {
        return "landing";
    }

    @RequestMapping("/login")
    public String viewLoginPage() {
        return loginPage;
    }

    @RequestMapping("/Register")
    public String viewRegisterPage() {
        return signUpPage;
    }

    @RequestMapping(path= "/ValidateLogin" , method = RequestMethod.POST)
    public String ValidateLogin(@ModelAttribute("loginUser")UserDTO userDto, HttpSession session,BindingResult errorList) {
        String returnPath="";
        userService = new UserServiceImpl(); 
        try {
//          if(session.getAttribute("loggedInUser") == null){
            if(Utils.isNotNull(userDto.getEmail())) {
                if(Utils.isNotNull(userDto.getPassword())) {
                    UserModel user = userService.validateLogin(userDto, null, errorList);
                    if(!errorList.hasErrors()) {
                        user = userService.validateLogin(userDto, null, errorList);
                        if(!errorList.hasErrors()) {
                            session.setAttribute("loggedInUser", user);

                            if(user.getRole() == Constants.UserRole.ADMIN) {
                                returnPath = "Admin";
                            }else if(user.getRole() == Constants.UserRole.STORE_MANAGER) {
                                returnPath = "StoreOwner";
                            }else {

                            }
                        }else {
                            returnPath = loginPage;
                        }
                    }else {
                        returnPath =loginPage;
