Question

我有一个控制器ApiBundle\Controller\UserController，它包含以下内容：

<?php
namespace ApiBundle\Controller;

use Doctrine\ORM\EntityManager;

use FOS\RestBundle\Controller\Annotations\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Symfony\Component\HttpFoundation\Request;

use AppBundle\Entity\User;
use ApiBundle\Form\RegisterType;
use ApiBundle\Utility\ApiUtility;

class UserController extends ApiController
{
    /**
     * @var EntityManager $em
     */
    private $em;

    /**
     * UserController constructor.
     * @param EntityManager $entityManager
     */
    function __construct(EntityManager $em)
    {
        $this->em = $em;
    }

    /**
     * @Route("register")
     * @Method({"POST"})
     * @return \Symfony\Component\HttpFoundation\Response
     * @param Request $request
     */
    public function registerUser(Request $request)
    {
        $data = ApiUtility::getContentAsArray($request);

        $user = new User();
        $form = $this->createForm(new RegisterType(), $user);

        $form->submit($data);
        if($form->isValid()) {
            $user->setUsername($request->get('email'));
            $this->em->persist($user);
            $this->em->flush();
        }else{
            return ApiUtility::returnResponse($form->getErrors());
        }
    }
}

它扩展了API控制器，如下所示：

<?php
namespace ApiBundle\Controller;

use FOS\RestBundle\Controller\FOSRestController;


class ApiController extends FOSRestController
{
}

它有以下服务：

services:
    api.controller.user:
        class: ApiBundle\Controller\UserController
        public: false
        parent: api.controller
        arguments: ["@doctrine.orm.entity_manager"]

    api.controller:
        class: ApiBundle\Controller\ApiController
        calls:
         - [setContainer, ['@service_container']]

无论我做什么，我都无法注入容器。现在，当我试图通过构造函数将doctrine引入容器时，我得到Type error: Too few arguments to function ApiBundle\Controller\UserController::__construct(), 0 passed in app/cache/dev/classes.php on line 2230 and exactly 1 expected，如果我将其切换回$ this-＆gt; container-＆gt; get（'doctrine.orm.entity_manager'）或getEntityManager，我得到容器是null。我怎样才能解决这个问题？

Symfony 2.8中不会发生依赖注入
