我尝试使用springtaskscheduler更改实体，但由于springauditor找不到currentauditor，所以出现了rollbackexception。我甚至不知道我在哪里能读到如何解决我的问题。如果有人能帮我解答这个问题，我将非常感激？
原因：com.geleigeit.linenandflowers.config.auditor.auditorawareimpl.getcurrentauditor（auditorawareimpl）上的java.lang.nullpointerexception。java:12)~[classes/：？]位于org.springframework.data.auditing.auditinghandler.lambda$touchauditor$6（auditinghandler。java:193)~[spring-data-commons-2.3.1.发布。jar:2.3.1.release]在java.util.optional.map（可选。java:258) ~[?:?]

@Override
@Transactional
@Scheduled(fixedDelay=10000)
public void toInProgress() {
    String currentStatus = "QUEUE";
    String statusToSet = "IN_PROGRESS";
    OrderStatus currentOrderStatus = orderStatusRepository.findByStatus(currentStatus);
    OrderStatus orderStatusToSet = orderStatusRepository.findByStatus(statusToSet);
    try {
        List<Order> orders = repository.findAllByOrderStatus(currentOrderStatus);
        for(Order order : orders) {
            int diff = (int) ((new Date().getTime() - order.getCreatedDate().getTime()) / (24 * 60 * 60 * 100));
            if(diff >= 1) {
                order.setOrderStatus(orderStatusToSet);
                repository.save(order);
                logger.info("order status QUEUE was changed to IN_PROGRESS by order.{}", order.hashCode());
            }
        }
    } catch (NullPointerException e) {
        logger.info("no orders with status QUEUE");
    }
}
