$ em-> find（..）和$ em-> getRepository（..） - > find（..）之间的区别

Question

There is Entity

/**
 * @ORM\Entity(repositoryClass="Some\Namspace\CustomRepository")
 * @ORM\Table(name="image_type")
 */
class MyEntity{...}

and CustomRepository extends EntityRepository to override some methods like find or findAll

documentation says:

// $em instanceof EntityManager
$user = $em->find('MyProject\Domain\User', $id);

Essentially, EntityManager#find() is just a shortcut for the following:

$user = $em->getRepository('MyProject\Domain\User')->find($id);

link:doctrine-orm.readthedocs.org

but my CustomRepository works only with $em->getRepository('Entities\MyEntity')->find($id)

using $em->find('Entities\MyEntity',$id); ignoring my overrided methods in CustomRepository

---

• so is this a bug?
• or there's a difference between this construcions?
• how can i overide find,finAll,... methods for my entity without overriding EntityManager?

Edit (1)

using composer:

"require": {
    "doctrine/orm": "~2.4"
},

find code:

public function find($entityName, $id, $lockMode = null, $lockVersion = null)
{
    $class = $this->metadataFactory->getMetadataFor(ltrim($entityName, '\\'));

    if ( ! is_array($id)) {
        if ($class->isIdentifierComposite) {
            throw ORMInvalidArgumentException::invalidCompositeIdentifier();
        }

        $id = array($class->identifier[0] => $id);
    }
    ........... other ~100 lines
}

In doctrine 2.2 it doesn't seem to be any different - literally just a pass-through/shortcut for getRepository()->find()

http://www.doctrine-project.org/api/orm/2.2/source-class-Doctrine.ORM.EntityManager.html#348

public function find($entityName, $identifier, $lockMode = LockMode::NONE, $lockVersion = null)
{
    return $this->getRepository($entityName)->find($identifier, $lockMode, $lockVersion);
}

Thoughts:

• What version of doctrine?
• Any chance you have a customized EntityManager?
