只有两种方法可以做到这一点：要么使用插入前生成的非亮片id（UUID），要么在每次插入（刷新）后检索最后一个插入id。
安装 ramsey/uuid 生成uuid。

foreach ($header as $key => $value) {
    $clientRecordAdditionalData  = new ClientRecordAdditionalData();
    $clientRecordAdditionalData->setId(Uuid::uuid4());
    $clientRecordAdditionalData->setName($value);
    $clientRecordAdditionalData->setValue($data[$key]);
    $clientRecordAdditionalData->setRecord($record);
    $em->persist($clientRecordAdditionalData);
}

public function saveAdditionalDataForRecord($header, $data, $record)
{
    $em = $this->getEntityManager();

    $ids = array();
    $objects = array();

    foreach ($header as $key => $value) {
        $clientRecordAdditionalData  = new ClientRecordAdditionalData();
        $clientRecordAdditionalData->setName($value);
        $clientRecordAdditionalData->setValue($data[$key]);
        $clientRecordAdditionalData->setRecord($record);
        $em->persist($clientRecordAdditionalData);

        $objects[] = $clientRecordAdditionalData;
    }

    $em->flush();

    foreach($objects as $object)
    {
        $ids[] = $object->id;
    }

    return $ids;

}
