symfony - Symfony (5.1) Doctrine Event Listener 被触发，但不是 Entity Listener

Question

使用Symfony 官方文档，我正在清理一些代码，并想在 Symfony 中替换一个 Doctrine 事件监听器（工作）：

namespace App\EventListener;

use App\Entity\Comment;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class CommentAuthorAssignmentListener
{
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function prePersist(Comment $comment, LifecycleEventArgs $event)
    {
        dump($comment, $event); exit;
        $comment->setAuthor($this->tokenStorage->getToken()->getUser());
    }
}

services:
    App\EventListener\CommentAuthorAssignmentListener:
        autowire: true 
        tags:
            - { name: doctrine.event_listener, event: prePersist }

使用更具体的实体侦听器（没有错误但根本没有启动）：

namespace App\EventListener;

use App\Entity\Comment;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class CommentAuthorAssignmentListener
{
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function prePersist(Comment $comment, LifecycleEventArgs $event)
    {
        $comment->setAuthor($this->tokenStorage->getToken()->getUser());
    }
}

services:
    App\EventListener\CommentAuthorAssignmentListener:
        autowire: true 
        tags:
            - { name: doctrine.entity_listener , entity: 'App\Entity\Comment', event: prePersist }

一些注意事项：

• 我确实跑了cache:clear
• 用例：显式持久化（新创建的）

看起来你打错了：

 # these are the options required to define the entity listener
 name: 'doctrine.orm.entity_listener'
 event: 'postUpdate'
 entity: 'App\Entity\User'

注意“.orm”。在标签名称中，因此对于您的用例：

services:
    App\EventListener\CommentAuthorAssignmentListener:
        autowire: true 
        tags:
            - { name: doctrine.orm.entity_listener , entity: 'App\Entity\Comment', event: prePersist }
