我目前正在使用Symfony2,我收到此错误消息:

未定义的方法'getDoctrine'.方法名称必须以findBy或findOneBy开头!500内部服务器错误 - BadMethodCallException

这是我的实体类:

 <?php

namespace Gestionresiduos\ResiduoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
* @ORM\Entity(repositoryClass="ResiduoRepository")
*/

class BodegaContieneResiduo
{


    /**
    * @ORM\Id
    * @ORM\column(type="integer")
    * @ORM\GeneratedValue
    */

    protected $idContiene;

.....

}

这是Controller的页面Action方法:

 <?php

namespace Gestionresiduos\ResiduoBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DefaultController extends Controller
{
    public function portadaAction()
    {
        $em = $this->getDoctrine()->getEntityManager();

        $ofertas= $em->getRepository('ResiduoBundle:BodegaContieneResiduo')->findResiduosAlmacenados();
        return $this->render('ResiduoBundle:Default:index.html.twig');
    }
}

这是我的EntityRepository:

    <?php
namespace Gestionresiduos\ResiduoBundle\Entity;

use Doctrine\ORM\EntityRepository;

class ResiduoRepository extends EntityRepository
{

    public function findResiduosAlmacenados()
    {
        $em = $this->getDoctrine()->getEntityManager();
        $consulta = $em->createQuery('SELECT r FROM ResiduoBundle:BodegaContieneResiduo');
        return …

我正在使用knp snappy bundle从我的应用程序生成报告.但是不起作用,当我调用我的控制器生成pdf时会抛出下一个错误:
