Hibernate setter更改不相关的列

Question

您好我正在尝试更新数据库中的多条记录，如果它们通过if语句。我想更新一个列，但是当我这样做时，它也会更新其他列。

表：约会

id |取消|时间| Doctor_id

代码：

public void cancelDoctorsAppoitmentsByDateBetweenTimeInterval(int idDoctor, Date date, Time from, Time to){
        from = new java.sql.Time((long) (from.getTime() - 1.14e+6));
        List<Appointment> appointments = getDoctorsAppointmentsByDate(idDoctor, date);
        for(Appointment appointment : appointments) {
            if(appointment.getDate().equals(date) && appointment.getTime().after(from) && appointment.getTime().before(to)
                    && !appointment.isCanceled()){

                Appointment appointmentToUpdate = currentSession().find(Appointment.class, appointment.getId());
                appointmentToUpdate.setCanceled(true);
            }
        }
    }

当我将取消设为真时。数据库更新也列为时间（它比以前更快地设置1小时）。为什么会这样？
