我很沮丧，因为我写的这些Java代码块。我编写这些代码块来检查数据的座位可用性状态，然后保存预订数据。在比较过程之后，我注意到我的主座位表中的数据已经更新了，我很确定代码不应该更新我的主座位表中的数据。下面是该代码的片段。

public List<CheckInSeatResponse> getGroupSeatData(Long serviceId, Date departDate, String departGroup, String destinationGroup, Long busId) {
    try {
        List<CheckInSeatResponse> manifestData = manifestPassengerRepository.getGroupSeatData( departDate, departGroup, destinationGroup, busId, serviceId);
        return manifestData;
    } catch (Exception e) {
        log.error(e.getMessage());
        return null;
    }
}

public List<Seat> getGroupSeatMap(Long serviceId, Date departDate, String departGroup, String destinationGroup, Long busId) {
    try {
        List<CheckInSeatResponse> manifestData = getGroupSeatData( serviceId, departDate, departGroup, destinationGroup, busId);
        List<Seat> seatData = seatBusRepository.findByBusIdOrderByIdAsc(busId);
        List<Seat> seatMap = new ArrayList<>();
        if (manifestData != null) {
            for (Seat seat : seatData) {
                Seat newSeat = seat;
                for (CheckInSeatResponse seatCheck : manifestData) {
                    if (seatCheck.getSeatNumber() != null && seatCheck.getSeatNumber().equals(seat.getSeatNumber())) {
                        newSeat.setSeatStatus("notAvailable");
                    }
                }
                seatMap.add(newSeat);
            }
            return seatMap;
        } else {
            return seatData;
        }
    } catch (Exception e) {
        log.error(e.getMessage());
        return null;
    }
}

这里的检查过程代码

List<Seat> seats = manifestService.getGroupSeatMap(
        reservation.getServiceBusId(),
        reservation.getDepartureDate(),
        depart.getGroupDestination(),
        destination.getGroupDestination(),
        request.getDepartBusId());
for (DetailCheckInResultResponse passenger : request.getPassenggerDepart()) {
    for (Seat seat : seats) {
        if (passenger.getSeat().equals(seat.getSeatNumber()) && "notAvailable".equals(seat.getSeatStatus())) {
            response.setStatus("failed");
            response.setMessage("Seat " + seat.getSeatNumber() + " not available");
            return response;
        }
    }
}
if (reservation.getReservationType()) {
    List<Seat> seatRets = manifestService.getGroupSeatMap(
            reservation.getServiceBusId(),
            reservation.getReturnDate(),
            destination.getGroupDestination(),
            depart.getGroupDestination(),
            request.getReturnBusId());
    for (DetailCheckInResultResponse passenger : request.getPassenggerReturn()) {
        for (Seat seat : seatRets) {
            if (passenger.getSeat().equals(seat.getSeatNumber()) && "notAvailable".equals(seat.getSeatStatus())) {
                response.setStatus("failed");
                response.setMessage("Seat " + seat.getSeatNumber() + " not available");
                return response;
            }
        }
    }
}

我在这个代码块上做错了什么？

请帮帮我先谢谢你。

我尝试将数据转换为字符串列表，并将其解析为JSON，这样数据就不会被更改。它的工作，但我相信这需要更多的资源，所以我希望在主座位表座位状态没有更新后保存预订数据与我目前的代码。
