Question

我只是按照自定义指南操作，我遇到了ProductFactoryInterface（http://docs.sylius.org/en/1.0/customization/factory.html）的自定义示例问题

我总是得到同样的错误：

编译错误：AppBundle \ Factory \ ProductFactory :: createWithVariant（）的声明： Sylius \ Component \ Core \ Model \ ProductInterface必须兼容 Sylius \分量\产品\厂\ ProductFactoryInterface :: createWithVariant（）： Sylius \组件\产品\型号\ ProductInterface

我做错了什么？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;
    }
}

如果您在顶部更改此使用声明：

use Sylius\Component\Core\Model\ProductInterface;

使用：

use Sylius\Component\Product\Model\ProductInterface;

有些接口在1.0.0发布之前就已经改变了，似乎并非所有文档都相应地反映了这些变化。
