Question

我的此订阅者位于AppBundle\DoctrineListeners正文中

namespace AppBundle\DoctrineListeners;

use Doctrine\Common\EventSubscriber;
use Doctrine\ORM\Event\OnFlushEventArgs;
use AppBundle\Entity\Bing\KeyWordReport;
use Doctrine\ORM\Events;

/**
 * Listener used to on update fielt create history
 */
class KeywordSubscriber implements EventSubscriber
{
    public function onFlush(OnFlushEventArgs $args)
    {
        throw new \Exception("Error Processing Request", 1); //for testing 

        $em  = $args->getEntityManager();
        $uow = $em->getUnitOfWork();

        foreach ($uow->getScheduledEntityUpdates() as $updated) {
            if ($updated instanceof KeyWordReport) {
                //do some work
            }
        }

        $uow->computeChangeSets();
    }

    public function getSubscribedEvents()
    {
        return [Events::onFlush => ['onFlush', 10], Events::preUpdate];
    }
}

我使用symfony 3.3中引入的autoconfigure

service.yml

services:
    # default configuration for services in *this* file
    _defaults:
        # automatically injects dependencies in your services
        autowire: true
        # automatically registers your services as commands, event subscribers, etc.
        autoconfigure: true
        # this means you cannot fetch services directly from the container via $container->get()
        # if you need to do this, you can override this setting on individual services
        public: false

实体中的

我在注释* @ORM\EntityListeners({"AppBundle\DoctrineListeners\KeywordSubscriber"}) 为什么不执行？

As @YannEugonénoted in comment - EventSubscribes和Doctrine EntityListeners是不同的东西。 Symfony中的EventListeners为registered manually：

namespace AppBundle\DoctrineListeners;

use Doctrine\ORM\Event\OnFlushEventArgs;
use AppBundle\Entity\Bing\KeyWordReport;

class KeywordListener
{
    public function onFlush(OnFlushEventArgs $eventArgs)
    {
        $em = $eventArgs->getEntityManager();
        $uow = $em->getUnitOfWork();

        foreach ($uow->getScheduledEntityInsertions() as $entity) {
            // … some action
        }

        foreach ($uow->getScheduledEntityUpdates() as $entity) {
            // … some action
        }

        foreach ($uow->getScheduledEntityDeletions() as $entity) {
            // … some action
        }

        foreach ($uow->getScheduledCollectionDeletions() as $col) {
            // … some action
        }

        foreach ($uow->getScheduledCollectionUpdates() as $col) {
            // … some action
        }
    }
}

#services.yml
services:
    # …

    AppBundle\DoctrineListeners\KeywordListener:
        tags:
            - { name: doctrine.event_listener, event: onFlush }

Symfony3.3，Doctrine2。 EventSubscriber，更新未执行
