            ArrayList<AirHotelVO> al = (ArrayList<AirHotelVO>)this.getMDMDAO().executeQuery(selectAir, new BeanListProcessor(AirHotelVO.class));
            System.out.println("---打印a---"+al.size());
            
            for (int i = 0; i < al.size(); i++) {
                AirHotelVO airHotelVO = (AirHotelVO) al.get(i);
                System.out.println("---voAirHotelVO---"+airHotelVO);
                System.out.println("---voAirHotelVO---"+airHotelVO.gethotelCd());
                System.out.println("---voAirHotelVO---"+airHotelVO.getrjCommission());
                System.out.println("---voAirHotelVO---"+airHotelVO.getrjMaxPrice());
            }
