Doctrine存储库“Doctrine \ ORM \ EntityRepository”必须在symfony2中实现UserProviderInterface

Question

登录时我遇到上述错误。使用security.yml中的属性选项，它正在工作。我在我的实体类中添加了@ORM\Entity(repositoryClass="versionR\userBundle\Entity\UserRepository")行，dobule检查了路径，清除了缓存但没有运气。

用户实体类

<?php

用户存储库类

<?php

namespace versionR\userBundle\Entity;

use Doctrine\ORM\EntityRepository;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\User\UserProviderInterface;
/**
 * UserRepository
 *
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class UserRepository extends EntityRepository implements UserProviderInterface
{
    /**
     * @param string $username
     * @return \versionR\userBundle\Entity\User
     */
    public function loadUserByUsername($username)
    {
        return $this->findOneBy(array('username' => $username));
    }

    public function refreshUser(UserInterface $user)
    {
        $class = get_class($user);
        if (!$this->supportsClass($class)) {
            throw new UnsupportedUserException(
                sprintf(
                    'Instances of "%s" are not supported.',
                    $class
                )
            );
        }

        return $this->find($user->getId());
    }

    public function supportsClass($class)
    {
        return $this->getEntityName() === $class
        || is_subclass_of($class, $this->getEntityName());
    }
}

这两个类都在Entity目录中。有任何建议可以解决这个问题。我正在使用symfony 2.5.2
