Как сохранить список товаров после нажатия на кнопку

Question

Я хочу сохранить список продуктов в базе данных после нажатия кнопки заказа, он не сохраняется. Я использовал идентификатор клиента, идентификатор продукта, идентификатор корзины, но не сохранил в базе данных.

проверьте мой код orderContoller ..

Корзина. jsp

 <form:form action="/order"  method="POST" modelAttribute="orderModel">
   <table class="table table-striped table-hover table-bordered">
        <c:forEach items="${listCart}" var="items" varStatus="status">
            <tr>
                <td><form:checkbox path="${items.id}" /></td>
                <td style="text-align: center">${items.id}</td>
                <td style="text-align: center">${items.name}</td>
                <td style="text-align: center"><fmt:formatNumber type="currency">${items.price} 
     </fmt:formatNumber></td>
                <td>
            </tr>
        </c:forEach>
    </table>
    <div class="col-md-5">
    <a class="btn btn-light btn-xl" href=" ">Order Now!</a>
        </div>
</form:form> 

orderController.class

    @RequestMapping("/order")
   public ModelAndView createOrder() {
    customerOrderModel customerOrder = new customerOrderModel();
    Cart cart = cartdao.getCartByID(id);
    customerOrder.setCart(cart);

    CustomerModel customer = cart.getCustomer();
    customerOrder.setCustomerID(customer);
    customerOrder.setBillingAddress(customer.getBillingAddress());
    customerOrder.setShippingAddress(customer.getShippingAddress());

    orderDao.addCustomerOrder(customerOrder);

    return new ModelAndView("Cart","orderModel",new customerOrderModel());

Cart.class

   @Entity
   public class Cart {

@Id
@GeneratedValue
private int id;
private String name;
private BigDecimal price;
private int quantity;

private CustomerModel customer;

Это класс модели клиента.
