嗨，我有一个onFlush侦听器：

<?php

namespace FM\AppBundle\EventListener;

use FM\AdminBundle\Entity\Address\DeliveryAddress;
use Doctrine\ORM\Event\OnFlushEventArgs;

class DeliveryAddressListener
{
    /**
     * @param OnFlushEventArgs $args
     */
    public function onFlush(OnFlushEventArgs $args)
    {
        $em = $args->getEntityManager();
        $uow = $em->getUnitOfWork();

        foreach ($uow->getScheduledEntityUpdates() as $entity) {
            if ($entity instanceof DeliveryAddress) {
                $this->addPostalToUser($entity, $args);
            }
        }
    }

    /**
     * @param DeliveryAddress  $deliveryAddress
     * @param OnFlushEventArgs $args
     */
    public function addPostalToUser(DeliveryAddress $deliveryAddress, OnFlushEventArgs $args)
    {
        $em = $args->getEntityManager();
        $user = $deliveryAddress->getOwner();

        $user->setPostalCode($deliveryAddress->getZipCode());
    }
}

service.yml：

delivery_address.listener:
    class: FM\AppBundle\EventListener\DeliveryAddressListener
    tags:
        - { name: doctrine.event_listener, event: onFlush …
