遵循Sylius定制工厂指南示例时出错

Question

我只是在遵循自定义指南，并且在ProductFactoryInterface（ http://docs.sylius.org/en/1.0/customization/factory.html ）的自定义示例中遇到了问题

我总是得到相同的错误：

编译错误：AppBundle \\ Factory \\ ProductFactory :: createWithVariant（）的声明：Sylius \\ Component \\ Core \\ Model \\ ProductInterface必须与Sylius \\ Component \\ Product \\ Factory \\ ProductFactoryInterface :: createWithVariant（）：Sylius \\ Component \\ Product \\型号\\产品接口

我究竟做错了什么？ 这是我的代码：

namespace AppBundle\Factory;

use Sylius\Component\Core\Model\ProductInterface;
use Sylius\Component\Product\Factory\ProductFactoryInterface;

class ProductFactory implements ProductFactoryInterface
{
    /**
     * @var ProductFactoryInterface
     */
    private $decoratedFactory;

    /**
     * @param ProductFactoryInterface $factory
     */
    public function __construct(ProductFactoryInterface $factory)
    {
        $this->decoratedFactory = $factory;
    }

    /**
     * {@inheritdoc}
     */
    public function createNew(): ProductInterface
    {
        return $this->decoratedFactory->createNew();
    }

    /**
     * {@inheritdoc}
     */
    public function createWithVariant(): ProductInterface
    {
        return $this->decoratedFactory->createWithVariant();
    }

    /**
     * @return ProductInterface
     */
    public function createDisabled(): ProductInterface
    {
        /** @var ProductInterface $product */
        $product = $this->decoratedFactory->createNew();

        $product->setEnabled(false);

        return $product;
    }
}

如果您首先更改此use语句：

use Sylius\Component\Core\Model\ProductInterface;

带有：

use Sylius\Component\Product\Model\ProductInterface;

在1.0.0版本之前，某些接口已更改，似乎并非所有文档都相应地反映了此更改。
