hibernate 批量更新时为什么只更新最后一条记录呢?

private void updateTempDate(List<ElBizInParkBooking>list) {
for (ElBizInParkBooking elBizInParkBooking : list) {
ElBizInParkBooking new_ElBizInParkBooking = inParkDaoImpl.getInParkBookingById(elBizInParkBooking.getInParkBookingId());
String startTime = elBizInParkBooking.getDispacthTime().split("-")[0];
String endTime   = elBizInParkBooking.getDispacthTime().split("-")[1];
new_ElBizInParkBooking.setTempStartDate(DateUtils.formatDateFromString(DateUtils.dateToString(new Date(), "yyyy-MM-dd"),startTime));
new_ElBizInParkBooking.setTempEndDate(DateUtils.formatDateFromString(DateUtils.dateToString(new Date(), "yyyy-MM-dd"),endTime));
inParkDaoImpl.update(new_ElBizInParkBooking);
}
}
service层中的dispacth方法调这个updateTempDate方法.updateTempDate中循环更新elBizInParkBooking .这个没问题.同样的操作在别的地方如:service层中的disPatchAll调用generalInstruction public void disPatchAll(String years) {
String[] days_to_show_format = years.split(",");
List<ElBizInParkBooking>all_result = getAllResult(days_to_show_format,null);
for (ElBizInParkBooking elBizInParkBooking : all_result) {
elBizInParkBooking.setFormatBDate(DateUtils.dateToString(elBizInParkBooking.getTempStartDate(), "yyyy"));
elBizInParkBooking.setDispacthTimeId(elBizInParkBooking.getTempDateId());
elBizInParkBooking.setBStartTime(DateUtils.dateToString(elBizInParkBooking.getTempStartDate(), "HH:mm:ss"));
elBizInParkBooking.setBEndTime(DateUtils.dateToString(elBizInParkBooking.getTempEndDate(), "HH:mm:ss"));
generalInstruction(elBizInParkBooking);
}
}
generalInstruction 中进行批量更新
public void generalInstruction(ElBizInParkBooking inParkBooking){
...
   
inParkDaoImpl.update(new_InParkBooking);
// inParkDaoImpl.flush();
}
老是只更新最后一个记录.如果加上flush的话就没问题.但是这样的话.事务就没意义了..相关的事务配置文件:
