MongoDB类文档不存在symfony 2

Question

我刚刚用fosuserbundle和DoctrinemongodbBundle安装了symfony2。

FOS配置了mongodb并且运行良好

我尝试在mongodb文档中设置并获取一些数据

这是我的文件：

<?php
// src/Acme/UserBundle/Document/Video.php

namespace Tube\VideoBundle\Document;

use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

/**
 * @MongoDB\Document
 */
class Video
{
    /**
     * @MongoDB\Id(strategy="auto")
     */
    protected $id;

    /**
     * @MongoDB\Int
     */
    protected $uid;

    /**
     * @MongoDB\String
     */
    protected $type;

    /**
     * @MongoDB\String
     */
    protected $embed;

    /**
     * @MongoDB\String
     */
    protected $url;



    /**
     * Get id
     *
     * @return id $id
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set uid
     *
     * @param int $uid
     * @return self
     */
    public function setUid($uid)
    {
        $this->uid = $uid;
        return $this;
    }

    ......
}

这是我的控制器：

<?php

namespace Tube\VideoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Tube\VideoBundle\Document\Video;


class DefaultController extends Controller
{
    public function addVideo($uid, $type, $embed, $url)
    {
        $video = new Video;

        $video->setUid($uid);
        $video->setType($type);
        $video->setEmbed($embed);
        $video->setUrl($url);

        $em = $this->getDoctrine()->getManager();
        $em->persist($video);
        $em->flush();

        return new Response($video->getId());
    }

    public function indexAction()
    {
        $video = $this->addVideo(1, "YouTube", '<iframe width="560" height="315" src="//www.youtube.com/embed/pA8Kzh_GWvw?list=UUEJFNw_gfbaoJnHfFguvI_w" frameborder="0" allowfullscreen></iframe>', "http://youtu.be/pA8Kzh_GWvw?list=UUEJFNw_gfbaoJnHfFguvI_w");

        return $this->render('TubeVideoBundle:Default:index.html.twig', array('id' => $video));
    }
}

Symfony错误：

The class 'Tube\VideoBundle\Document\Video' was not found in the chain configured namespaces 

我哪里错了？
