symfony - 如何将实体从一个捆绑包扩展到另一个捆绑包

Question

我已经创建了一个 symfony 包。我想单独为我的应用程序添加另一个包。所以现在我面临一个问题，即如何将实体从旧包扩展到新创建的包。我正常扩展它，但它给出了错误。

我有这两个捆绑包，

MyFirstBundle
MySecondBundle

MyFirstBundle 实体，

namespace My\FirstBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 *
 * @ORM\Table(name="companies")
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks 
 */
class Company
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     *
     * @Groups({"list_companies", "company_details", "ad_details"})
     */
     private $id;

    /**
     * @ORM\Column(name="name", type="string", length=50, nullable=true)'
     *
     * @Groups({"ad_details"})
     */
     private $name;

MySecondBundle 实体，

namespace My\SecondBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use My\FirstBundle\Entity\Company as BaseCompany;

class Companies extends BaseCompany 
{
    public function __construct() {
        parent::__construct();
    }

}

我不确定我是否可以像这样扩展我的实体。使用此实体创建表单时出现错误

Class "MySecondBundle:companies" seems not to be a managed Doctrine entity. Did you forget to map it?

您还需要为第二个实体添加教义注释。

/**
 *
 * @ORM\Table(name="companies")
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks 
 */
class Companies extends BaseCompany 
{
    public function __construct() {
        parent::__construct();
    }

}
