相关疑难解决方法(0)

我一直在尝试调用Entity Manager构造函数:

function __construct()
{
    $this->getDoctrine()->getEntityManager();
    ...

但是,正如我在这个答案中看到的:Stackoverflow问题,它无法完成.

所以我想知道是否有办法实现它,因为我必须经常调用它,并希望在获取存储库后在构造函数中做一些事情.

编辑:

我试过@MKhalidJunaid回答:

//src/MSD/HomeBundle/Resources/config/services.yml
services:
  imageTransController.custom.service:
    class:  MSD\HomeBundle\Controller\ImageTransController
    arguments: 
        EntityManager: "@doctrine.orm.entity_manager"

-

//app/config/config.php
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: doctrine_extensions.yml }
- { resource: "@MSDHomeBundle/Resources/config/services.yml" }

-

//src/MSD/HomeBundle/Controller/ImageTransController.php
namespace MSD\HomeBundle\Controller;

use Doctrine\ORM\EntityManager;
use MSD\HomeBundle\Entity\Imagen as Imagen;
use MSD\HomeBundle\Controller\HomeController as HomeController;


class ImageTransController extends HomeController
{
    protected $em ;

    function __construct(EntityManager $entityManager)
    {
    ...

但我收到这个错误:

Catchable Fatal Error: Catchable Fatal Error: …
