嘿，伙计们，我的代码有问题。由于某些原因，当我尝试将值更改为false时，它不会反映在我的sql数据库中。我调试过，它确实是通过java设置的，但是它没有传输过来。我正在处理一个通知服务类，它将其中的值设置为true没有问题，但是我的postmapping方法不起作用。我将在下面为add flight和我的通知服务发布一段代码。

@PostMapping("addflight")
String addflight(@ModelAttribute Flights flights, @SessionAttribute(required = false) String loggedInuser) {
    Accounts a = accountsRepository.findByEmail(loggedInuser).get();
    flightsRepository.saveAndFlush(flights);
    List<Flights> flightsList =  flightsRepository.findByAccountsOrderByDateofflightAsc(a);
    if(flightsList.size() != 0) {
        Flights lastFlight = flightsList.get(flightsList.size() - 1);
        LocalDate today = LocalDate.now();
        long days = 0;
        days = ChronoUnit.DAYS.between(lastFlight.getDateofflight(), today);
        if(days >= 46){
           a.setNotified(false);
        }
    }
    return "redirect:logbook";
}
