Symfony覆盖另一个包的存储库不会覆盖它

Question

我想覆盖另一个包的实体和存储库

所以

我想覆盖

src/MyBundle/Entity/Product
src/MyBundle/Entity/ProductRepository

所以我创建了另一个包AppBundle

src/AppBundle/Entity/Product extends src/MyBundle/Entity/Product
src/AppBundle/Entity/ProductRepository extends src/MyBundle/Entity/ProductRepository

所以在AppBundle中我想添加一些属性，并且还想在ProductRepository中编写自定义查询。

所以

class AppBundle extends Bundle
{
    public function getParent()
    {
        return 'MyBundle';
    }
}

In my AppBundle entity i have specify repository of src/AppBundle/Entity/ProductRepository

我该怎么做？

 * @ORM\Entity(repositoryClass="MyBundle\Entity\ProductRepository")
 */
class Product extends Base
{
}

$ em-＆gt; getRepository（'AppBundle：Product'）提供了

的存储库

MyBundle\Entity\ProductRepository
