Shopware 6：如何使用自动布线注入实体存储库
Shopware 6: How to inject an entity repository using autowiring
问：
通过 services.xml 向实体存储库注入 Shopware 6 的“经典”方式类似于
# your service/controller
private EntityRepository $productRepository;
...
public function __construct(
EntityRepository $productRepository
) {
$this->$productRepository = $productRepository;
}
...
<!-- your services.xml -->
<service id="...">
<argument type="service" id="product.repository"/>
</service>
现在，如果我想使用 Symfony 的自动布线 - 与上述符号等价的是什么？
（换句话说，我的观点是如何告诉 Symfony 我希望 product.repository 服务是有线的，而不仅仅是通用的 EntityRepository？

我发现的解决方案实际上相当简单明了：-）使用 Autowire 参数属性指定构造函数，如下所示：
private readonly EntityRepository $productRepository;
...
public function __construct(
#[Autowire(service: 'product.repository')] EntityRepository $productRepository
) {
$this->productRepository = $productRepository;
}
如果您遵守 Shopware 的命名约定，您甚至可以省略 Autowire 参数，在上面的示例中，变量名称将被正确解析为服务。（由 @Alex 提供，评论见下文）$productRepository'product.repository'

剧透：这甚至没有必要..Shopware / Symfony从变量名称中知道要注入什么！$productRepository

快速解释它是如何在内部工作的，以便您更好地理解。
Shopware首先查找定义，然后在流程中动态创建存储库。CompilerPass
在容器（属性）中，它最终如下所示：aliasDefinitions
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $aclRoleRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $aclUserRoleRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appActionButtonRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appActionButtonTranslationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appCmsBlockRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appCmsBlockTranslationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appFlowActionRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appFlowActionTranslationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appFlowEventRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appPaymentMethodRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appScriptConditionRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appScriptConditionTranslationReposito = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appTemplateRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $appTranslationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $customFieldRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $customFieldSetRelationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $customFieldSetRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $languageRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $logEntryRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $pluginRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $pluginTranslationRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $scheduledTaskRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $scriptRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $seoUrlRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $seoUrlTemplateRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $versionCommitDataRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $versionCommitRepository = {Symfony\Component\DependencyInjection\Alias}
Shopware\Core\Framework\DataAbstractionLayer\EntityRepository $versionRepository = {Symfony\Component\DependencyInjection\Alias}
[.....]
[.....]
[.....]
[.....]
所以，换句话说，通常你有这些定义：
MySampleDefinition.php
HelloWorldDefinition.php
MyCustomEntityDefinition.php
您将能够在 PHP 文件上自动访问这样的存储库：
use Shopware\Core\Framework\DataAbstractionLayer\EntityRepository;
public function __construct(
private EntityRepository $mySampleRepository,
private EntityRepository $helloWorldRepository,
private EntityRepository $myCustomEntityRepository,
) {
}
无需担心手动定义存储库...但是，您必须保持模式的样子，否则您必须显式地传递它EntityRepository $myCustomEntityRepositoryservices.xml
