如何 create/get Shopware 6 中的自定义服务实例

Question

出于某种原因，我不完全了解如何获取自定义服务的简单实例。这是我到目前为止所遵循的文档：

https://developer.shopware.com/docs/guides/plugins/plugins/framework/data-handling

 class WritingData
{
    private $productRepository;
    private $taxRepository;

    public function __construct(EntityRepositoryInterface $productRepository, EntityRepositoryInterface $taxRepository)
    {
        $this->productRepository = $productRepository;
        $this->taxRepository = $taxRepository;
    }
}

services.xml也设置

<?xml version="1.0" ?>
    <services>
        <service id="Swag\BasicExample\Service\WritingData" >
            <argument type="service" id="product.repository"/>
            <argument type="service" id="tax.repository"/>
        </service>
    </services>
</container>

问题是：如何在命令服务中获取 WrtingData 的实例？

Answer 1

您必须将自定义服务注入命令服务，就像将存储库注入 WritingData 一样。您可以在 the Symfony documentation.

中找到有关容器和依赖项注入的更多信息

例如，如果这是您的命令服务：

class ExampleCommand extends Command
{
    private $writingData;

    public function __construct(WritingData $writingData)
    {
        $this->writingData = $writingData;
    }
}

然后你将 WritingData 注入到 services.xml 中的 ExampleCommand:

<service id="SwagBasicExample\Command\ExampleCommand">
    <argument type="service" id="Swag\BasicExample\Service\WritingData"/>
    <tag name="console.command"/>
</service>
