西利乌斯在添加项目后不记得购物车

我正在使用Sylius购物车和订单捆绑包，并尝试将商品添加到购物车并显示购物车中商品的摘要。 我遇到的问题是Symfony/Sylius忘记了它已经制作了一个购物车并向其中添加了物品。

如果我单击指向 sylius 购物车添加页面的链接，则由

{{ path('sylius_cart_item_add', {'productId': class.ClassID}) }}

不会发生任何错误。 如果我查看数据库，我可以看到在sylius_cart表和sylius_cart_item表中创建了一个新条目，其中包含正确的信息;但是，购物车摘要页面不显示任何内容，并认为购物车为空。

如果我尝试添加另一个项目，它会创建另一个新购物车，并立即忘记它制作了购物车。

我在应用程序内核中加载了以下捆绑包.php

public function registerBundles()
{
        $bundles = array(
            //bundles for using the shopping cart
            new FOS'RestBundle'FOSRestBundle(),
            new JMS'SerializerBundle'JMSSerializerBundle($this),
            new Sylius'Bundle'ResourceBundle'SyliusResourceBundle(),
            new WhiteOctober'PagerfantaBundle'WhiteOctoberPagerfantaBundle(),
            new Sylius'Bundle'MoneyBundle'SyliusMoneyBundle(),
            new Sylius'Bundle'OrderBundle'SyliusOrderBundle(),
            new Sylius'Bundle'CartBundle'SyliusCartBundle(),
            new Sylius'Bundle'SequenceBundle'SyliusSequenceBundle(),

            //bundles for styling with bootstrap 3
            new Mopa'Bundle'BootstrapBundle'MopaBootstrapBundle(),
            //mssql connection library
            new Realestate'MssqlBundle'RealestateMssqlBundle(),
            //default frameworks
            new Symfony'Bundle'FrameworkBundle'FrameworkBundle(),
            new Symfony'Bundle'SecurityBundle'SecurityBundle(),
            new Symfony'Bundle'TwigBundle'TwigBundle(),
            new Symfony'Bundle'MonologBundle'MonologBundle(),
            new Symfony'Bundle'SwiftmailerBundle'SwiftmailerBundle(),
            new Symfony'Bundle'AsseticBundle'AsseticBundle(),
            new Doctrine'Bundle'DoctrineBundle'DoctrineBundle(),
            new Sensio'Bundle'FrameworkExtraBundle'SensioFrameworkExtraBundle(),
            new CE'CEBundle'CEBundle(),
        );
        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Symfony'Bundle'WebProfilerBundle'WebProfilerBundle();
            $bundles[] = new Sensio'Bundle'DistributionBundle'SensioDistributionBundle();
            $bundles[] = new Sensio'Bundle'GeneratorBundle'SensioGeneratorBundle();
        }
        return $bundles;
}

我的项目解析程序类看起来像

namespace CE'CEBundle'Cart;
use Sylius'Component'Cart'Model'CartItemInterface;
use Sylius'Component'Cart'Resolver'ItemResolverInterface;
use Sylius'Component'Cart'Resolver'ItemResolvingException;
use Symfony'Component'HttpFoundation'Request;
use Doctrine'ORM'EntityManager;
class ItemResolver implements ItemResolverInterface
{
    private $entityManager;
    public function __construct(EntityManager $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function resolve(CartItemInterface $item, $data)
    {
        //grab the product ID
        $productId = $data->get('productId');

        if (!$productId || !$product = $this->getProductRepository()->find($productId)) {
            throw new ItemResolvingException('Requested product was not found');
        }
        $item->setProductId($product->getId());
        $item->setUnitPrice($product->getClassFee() * 100);
        return $item;
    }
    private function getProductRepository()
    {
        return $this->entityManager->getRepository('CEBundle:Product');
    }
}

我的购物车项类看起来像

namespace CE'CEBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
use Sylius'Component'Cart'Model'CartItem as BaseCartItem;
/**
 * @ORM'Entity
 * @ORM'Table(name="sylius_cart_item")
 */
class CartItem extends BaseCartItem
{
    /**
     * @ORM'Column(type="string", name="product_id", length=8)
     */
    private $productId;
    public function getProductId()
    {
        return $this->productId;
    }
    public function setProductId($Id)
    {
        $this->productId = $Id;
    }
}

值得注意的是，如果我查看Chrome开发人员工具中的"资源"选项卡，我可以看到当我将商品添加到购物车时，SYLIUS_SESSION确实设置了。

我尝试将存储更改为cookie而不是会话并倾倒文档，但是我不知道该怎么做才能解决此问题。 我的猜测可能是小东西，我只是不知道它是什么。

提前感谢您的任何帮助。
