Question

我尝试更新数据库值时遇到此异常。我必须在指令之前将editing字段设置为TRUE，最后设置为FALSE，或者在出现异常时。这是代码：

@Override
@SetEditingFleet
//  @UnSetEditingFleet
public void modifyFleet(User user, FleetForm fleetForm) throws Exception{
    databaseFleetsAndCarsServices.modifyFleet(user, fleetForm);
}

此方法调用@Async和@Transactional方法，在某些情况下，我必须使用false值重置编辑fleet参数更新（在setEditingFleet中我将字段设置为true）这是异步方法：

@Override
@Async
@Transactional(rollbackFor=Exception.class)
public void modifyFleet(User currentUser, FleetForm fleetForm) throws Exception {
    //Keep the progress status on DB
    fleetServices.setEditingProgress(fleetForm.getIdFleet(), "Start editing fleet");
    //SOme code
        //Keep the progress status on DB
        fleetServices.setEditingProgress(oldFleet.getIdFleet(), "");
//          throw new Exception("fleet has been restored Exception");
    }catch(Exception e){
        //Keep the progress status on DB
        fleetServices.setEditingProgress(oldFleet.getIdFleet(), "Sorry an error occured during the procedure, wait until restore is ended!");
        //Restore the file system procedure
        restoreProcedure(oldFleet.getIdFleet(), fleetFile, backupFolderFile);       
        //Keep the progress status on DB
        fleetServices.setEditingProgress(oldFleet.getIdFleet(), "");
        //Even with this exception set the fleet as not in editing
        utils.unSetEditingFleet(oldFleet.getIdFleet());
        throw new EditingException("fleet has been restored!");
    }
}

方法集编辑进度为@Transactional(propagation = Propagation.REQUIRES_NEW)，因为我必须实时向用户显示此String。即使unSetEditingFleet必须与REQUIRES_NEW一起使用，否则在发生错误时会回滚此数据库查询。 utils.unSetEditingFleet(Integer id)是一个不同的类，并有此说明：

@Transactional(propagation = Propagation.REQUIRES_NEW)
public void unSetEditingFleet(Integer idFleet) throws QueryException {
    try {
        fleetServices.setEditingFleet(idFleet, false);   
        for(Car car : carServices.findByFleetIdFleet(idFleet)){
            carServices.setEditingCar(car.getIdCar(), false);   //Unset cars associated with the fleet 
        }    
    }catch(Exception e){
        throw new QueryException(e);
    }
}

当代码调用setEditingCar时，我有例外：
