Symfony 3.1在表单中使用自定义存储库方法

// 实体类
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="AppBundle\Repository\CustomRepository")
 * @ORM\Table(name="my_entity")
 */
class MyEntity
{
    // 实体属性
    // ...
}

// 存储库类
namespace AppBundle\Repository;

use Doctrine\ORM\EntityRepository;

class CustomRepository extends EntityRepository
{
    public function customSave($data)
    {
        // 自定义存储逻辑
        // ...
    }

    public function customFind($id)
    {
        // 自定义检索逻辑
        // ...
    }
}

// 表单类型类
namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class MyEntityType extends AbstractType
{
    private $customRepository;

    public function __construct(CustomRepository $customRepository)
    {
        $this->customRepository = $customRepository;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // 表单字段
            // ...
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => 'AppBundle\Entity\MyEntity',
        ]);
    }
}
