没有扩展程序可以加载＆＃34; UserBundle \ Entity \ User＆＃34;

Question

我有这个自定义用户类：

namespace UserBundle\Entity;


use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 */
class User extends BaseUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
    public function setEmail($email)
    {
        $email = is_null($email) ? '' : $email;
        parent::setEmail($email);
        $this->setUsername($email);

        return $this;
    }
}

我还有包含在配置文件中的validation.yml：

UserBundle\Entity\User:
    properties:
    # Your custom fields in your user entity, here is an example with FirstName
        firstName:
            - NotBlank:
                message: acme_user.first_name.blank
                groups: [ "AcmeProfile" ]
            - Length:
                min: 2
                minMessage: acme_user.first_name.short
                max: 255
                maxMessage: acme_user.first_name.long
                groups: [ "AcmeProfile" ]



# Note: We still want to validate the email
# See FOSUserBundle/Resources/config/validation/orm.xml to understand
# the UniqueEntity constraint that was originally applied to both
# username and email fields
#
# As you can see, we are only applying the UniqueEntity constraint to
# the email field and not the username field.

当我尝试打开登录页面时，当我尝试更新数据库时，收到错误消息：
