如何通过symfony中的doctrine builder选择额外的字段并将其映射到实体？

use Doctrine\ORM\EntityManagerInterface;
use Doctrine\ORM\QueryBuilder;

class YourController
{
    private $entityManager;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function yourAction()
    {
        $queryBuilder = $this->entityManager->createQueryBuilder();

        $queryBuilder
            ->select('e.id', 'e.name', 'e.additionalField')
            ->from('App\Entity\YourEntity', 'e')
            ->addSelect('e.additionalField')
            ->andWhere('e.someCondition = :condition')
            ->setParameter('condition', 'someValue');

        $query = $queryBuilder->getQuery();
        $results = $query->getResult();

        // 将结果映射到实体类或DTO中
        // ...

        return $this->render('your_template.html.twig', [
            'results' => $results,
        ]);
    }
}
