问如果使用查询构建器获取数据，则postLoad不起作用

EN

class ProcessPostLoadListener
{
    public function postLoad(LifecycleEventArgs $args)
    {
        $em = $args->getEntityManager();
        $entity = $args->getEntity();
        if ($entity instanceof Process) {
              .
              .
              .
        }

    }
}

$qb = $this->createQueryBuilder('p')
    ->select('PARTIAL p.{id,answersInRelatedQuestionnaires}')
    ->where('p.id = :processId')
    ->setParameter('processId', $processId);
