嘗試從命名空間加載類「媒體」的「應用程序\ MediaBundle \實體」

我想一個資料圖片添加到我的管理類，但是我得到這個錯誤：嘗試從命名空間加載類「媒體」的「應用程序 MediaBundle 實體」

嘗試從命名空間加載類「媒體」「應用程序\ MediaBundle \實體」。您是否忘記了「使用」聲明「Sonata \ MediaBundle \ Model \ Media」，「Sonata \ MediaBundle \ Tests \ Entity \ Media」，「Sonata \ MediaBundle \ Tests \ Document \ Media」或「Sonata \ MediaBundle \ Tests \ PHPCR \ Media」？

我搜索了很多，但沒有解決方案。這是我的代碼

問題是配置文件config.yml在

> sonata_media: 
>  class: 
>   media: Application\Sonata\MediaBundle\Entity\Media 
>   gallery: Application\Sonata\MediaBundle\Entity\Gallery 
>   gallery_has_media: Application\Sonata\MediaBundle\Entity\GalleryHasMedia 
>   category: Application\Sonata\ClassificationBundle\Entity\Category
