它说：

type Status report

message

description The request sent by the client was syntactically incorrect.
Apache Tomcat/7.0.35

我的控制器代码是：

@RequestMapping(value = "/manageInventory.htm", method = RequestMethod.GET)
    public ModelAndView manageInventory(HttpSession session) {

        ArrayList<Product> products = new ArrayList<Product>();
        Manufacturer manufacturer = (Manufacturer) manufacturerDAO
                .getByUsername(((UserAccount) session.getAttribute("user"))
                        .getUsername());
        products = productDAO.getProductListByManufacturer(manufacturer
                .getManufacturerName());
        System.out.print(products.get(0).getProductName());
        ModelAndView view = new ModelAndView("manageInventory");
        view.addObject("products", products);
        InventoryItem inventoryItem = new InventoryItem();
        view.addObject("inventoryItem", inventoryItem);
        return view;
    }

    @RequestMapping(value = "/manufacture.htm", method = RequestMethod.POST)
    public ModelAndView manufactureProduct(HttpSession session, BindingResult result,
            @ModelAttribute("inventoryItem") @Valid InventoryItem inventoryItem) {

        System.out.print(result.getErrorCount()+" "+result.getAllErrors());

        ModelAndView view = null;
        if(!result.hasErrors())
        {
        Manufacturer manufacturer = manufacturerDAO
                .getByUsername(((UserAccount) (session.getAttribute("user")))
                        .getUsername());
        inventoryItem.setAvailability(true);
        inventoryItem.setManufacturer(manufacturer);
        manufacturer.getInventory().add(inventoryItem);
        manufacturerDAO.update(manufacturer);
        view =  new ModelAndView("done");
        }
        else
        {
            view = new ModelAndView("manageInventory");
        }
        return view;

    }

请帮忙。提前感谢。

我忘了在方法输入参数中添加

HttpServletRequest

。我添加了它，它开始工作。奇怪，但奏效了。：）
