Difference between ObjectManager and EntityManager in Symfony2?

任何人都可以建议我如何在构造函数中使用对象管理器，因为symfony会抛出错误。

Answer 1

doctrine_mongodb是一个返回Doctrine\Bundle\MongoDBBundle\ManagerRegistry对象的服务。您可以通过调用ObjectManager来获取getManager。

<?php


namespace Acme\StoreBundle\Security;

use Doctrine\Bundle\MongoDBBundle\ManagerRegistry;
// ...

class TokenAuthenticator extends AbstractGuardAuthenticator
{

    /**
    * @var Doctrine\Common\Persistence\ObjectManager
    */
    protected $om;

    // ...

    public function __construct(JWTEncoderInterface $jwtEncoder, ManagerRegistry $registry)
    {
        // ...
        $this->om = $registry->getManager();
    }
