Php Shopware：通过其ID获取文档编号

我需要通过其ID获取documentRepository中的documentNumber。 我正在执行一个“简单”的DAL请求来完成此操作，但由于某些原因，转储输出会给出空字段

这是我的订阅服务器，包含DAL请求：

<?php

use Shopware\Core\Framework\DataAbstractionLayer\EntityRepositoryInterface;

class OrderSubscriber implements EventSubscriberInterface
{

    /**
     * @ContainerInterface $container
     */
    private $container;

    /**
     * @var HmOrderService
     */
    private $service;

    /**
     * @var HmDocumentService
     */
    private $docService;

    /**
     * @var EntityRepositoryInterface
     */
    private $transmissionLogRepository;

    /**
     * @var EntityRepositoryInterface
     */
    private $transmissionRepository;

    /**
     * @var EntityRepositoryInterface
     */
    private $documentRepository;

    /**
     * @var EntityRepositoryInterface
     */
    private $orderRepository;

    public function __construct(ContainerInterface $container, HmOrderService $service, HmDocumentService $docService, EntityRepositoryInterface $transmissionLogRepository, EntityRepositoryInterface $transmissionRepository, EntityRepositoryInterface $documentRepository, EntityRepositoryInterface $orderRepository)
    {
        $this->container = $container;
        $this->service = $service;
        $this->docService = $docService;
        $this->transmissionLogRepository = $transmissionLogRepository;
        $this->transmissionRepository = $transmissionRepository;
        $this->documentRepository = $documentRepository;
        $this->orderRepository = $orderRepository;
    }

    public static function getSubscribedEvents(): array
    {
        return [
            CheckoutOrderPlacedEvent::class => 'onOrderPlaced',
        ];
    }

    public function onOrderPlaced(CheckoutOrderPlacedEvent $event): void
    {
        $order = $event->getOrder();

        if ($order instanceof OrderEntity) {
            $this->service->generateDocuments($order); //document correctly generated (I checked in the db)
            $document = $this->docService->getInvoice($order); //To get the documentId
            $documentObject = $this->documentRepository->search(new Criteria([ $document['id'] ]), \Shopware\Core\Framework\Context::createDefaultContext() );
            var_dump($documentObject);
            die('please man');
        }
   }
}

我还尝试直接转储getInvoice（）函数的结果，方法如下：

$document=$this->docService->getInvoice（$order）；
$contentD=$document['content']；
var_dump（$content）；
回声（“
”）；
if（strpos（$content，'Invoice'）！==false）{
回声“找到单词！”；
}否则{
回声“找不到单词！”；
}
死亡（‘mem’）；

这是$content d的输出，其中我看到“发票”一词，但strpos返回“找不到词”：

我是否忘记了services.xml中的use语句或其他内容，或者使用了错误的存储库？我100%确定文档的ID是正确的，我还尝试在数据库（表“document”）中手动获取ID，并获得了相同的行为

---

我发现了错误，以错误的方式获取存储库。 以下是获得它的正确方法：

/* @var EntityRepositoryInterface $docRepository */ 
$docRepository = $this->container->get('document.repository');

最后，我是这样得到发票号码的：

$document = $this->docService->getInvoice($order);

/* @var EntityRepositoryInterface $docRepository */
$docRepository = $this->container->get('document.repository');
$documentObject = $docRepository->search(new Criteria([ $document['id'] ]), $event->getContext());
$documentNumber = $documentObject->first()->getConfig()['custom']['invoiceNumber'];

/* @var EntityRepositoryInterface $docRepository */ 
$docRepository = $this->container->get('document.repository');

$document = $this->docService->getInvoice($order);

/* @var EntityRepositoryInterface $docRepository */
$docRepository = $this->container->get('document.repository');
$documentObject = $docRepository->search(new Criteria([ $document['id'] ]), $event->getContext());
$documentNumber = $documentObject->first()->getConfig()['custom']['invoiceNumber'];
