Doctrine orm 条令实体未包含在条令事件回调中

我有一对多关系的实体

TransactionItem--有许多-->付款

编辑：包括映射文件

Payment.yml映射文件

Akademia\Institution\Sales\Domain\Model\Payment\Payment:
    type: entity
    table: payments
    repositoryClass: Akademia\Institution\Sales\Infrastructure\Persistence\Doctrine\Payment\DoctrinePaymentRepository

    id:
        id:
            type: string
            length: 36

    fields:
        date:
            type: datetime

        amount:
            type: decimal
            precision: 11
            scale: 2


    manyToOne:
        transactionItem:
          targetEntity: Akademia\Institution\Sales\Domain\Model\TransactionItem
          inversedBy: payments
          joinColumn:
            name: transaction_item_id
            referencedColumnName: id

TransactionItem.yml映射

Akademia\Institution\Sales\Domain\Model\TransactionItem:
    type: entity
    table: transaction_items
    repositoryClass: Akademia\Institution\Sales\Infrastructure\Persistence\Doctrine\DoctrineTransactionItemRepository

    id:
        id:
            type: string
            length: 36

    fields:
        productId:
            type: string
            column: product_id

        productType:
            type: string
            column: product_type

        description:
            type: string

        quantity:
            type: integer

        price:
            type: decimal
            precision: 11
            scale: 2

        discount:
            type: decimal
            precision: 11
            scale: 2

        paid:
            type: boolean

        remarks:
            type: string
            nullable: true

    manyToOne:
        transaction:
            targetEntity: Akademia\Institution\Sales\Domain\Model\Transaction
            inversedBy: lineItems
            joinColumn:
                name: transaction_id
                referencedColumnName: id

    oneToMany:
        payments:
            targetEntity: Akademia\Institution\Sales\Domain\Model\Payment\Payment
            mappedBy: transactionItem
            cascade: ['persist']
            fetch: EAGER

我打电话的时候

$transactionItem->pay($amount, $date);
$entityManager->persist($transactionItem);
$entityManager->flush();

TransactionItem.php

public function pay($amount, \DateTime $date = null)
{
        $payment = new Payment(
            Uuid::uuid4()->toString(),
            $this,
            $amount,
            $date ?? new \DateTime());

        $this->payments[] = $payment;
}

我希望我可以在这里获得关于条令回调的

TransactionItem

：

服务.yml

services:
    app.doctrine_event_listener:
        class: AppBundle\Event\DomainEventListener
        arguments: ["@app.domain_event_dispatcher"]
        tags:
            - { name: doctrine.event_listener, event: postPersist }
            - { name: doctrine.event_listener, event: postUpdate }
            - { name: doctrine.event_listener, event: postRemove }
            - { name: doctrine.event_listener, event: postFlush }

    app.domain_event_dispatcher:
        class: AppBundle\Event\DefaultEventDispatcher

听众：

 class DomainEventListener
    {
        private $entities = array();

        /** @var DomainEventDispatcher */
        private $dispatcher;

        public function __construct(DomainEventDispatcher $dispatcher)
        {
            $this->dispatcher = $dispatcher;
        }

        public function postPersist($event)
        {
            $this->keepAggregateRoots($event);
        }

        public function postUpdate($event)
        {
            $this->keepAggregateRoots($event);
        }

        public function postRemove($event)
        {
            $this->keepAggregateRoots($event);
        }

        public function postFlush($event)
        {
            /** @var AggregateRoot $entity */
            VarDumper::dump($this->entities);die();
            foreach ($this->entities as $entity) {
                foreach ($entity->releaseEvents() as $anEvent) {
                    $this->dispatcher->dispatch($anEvent);
                }
            }

            $this->entities = array();
        }

        private function keepAggregateRoots($event)
        {
            $entity = $event->getEntity();
            if (!($entity instanceof AggregateRoot)) {
                return;
            }

            $this->entities[] = $entity;
        }
    }

但是在postFlush

VarDumper:：dump（$this->entities）上转储捕获的实体时

我只是得到一个空数组结果

注:
TransactionItem
扩展了
AggregateRoot
，但付款不扩展

但至少我希望
TransactionItem
在场

仅仅添加子关系不会将其包含在条令事件中吗？

如何手动告诉条令，
TransactionItem
应该出现在postFlush事件中？

编辑：未调用在postUpdate内部转储。

public function postUpdate($event)
    {
        $this->keepAggregateRoots($event);
        VarDumper::dump('Inside postUpdate');
        VarDumper::dump($this->entities);die();
    }

是否确实调用了这些方法？你似乎在创建一个事件订阅者，而不是我的监听器。我想是这样的，因为在postPersist事件中调用
VarDumper:：dump（'Im inside postPersist'）
与在postFlush中发布的代码一样有效。我将编辑帖子以包含services.yml配置，事件
postFlush
是否包含实体？否，我得到的是空数组。即使在postPersist中转储也会导致空数组。我怀疑这是因为我只是在TransactionItem上添加子实体，而没有更改任何其他字段（只是猜测），我认为你是对的。未调用postUpdate。但是为什么？你确定这些方法都被调用了吗？你似乎在创建一个事件订阅者，而不是我的监听器。我想是这样的，因为在postPersist事件中调用
