事务回滚 @Transactional

 	@Override
    @Transactional
    public Response cancel(String ids) {
        if (DataUtil.isNotEmpty(ids)) {
            String[] vehicleIds = ids.split(",");
            List<ResVehicleVerifyStatus> listStatus = new ArrayList<>();
            List<ResVehicleVerifyRecord> listRecord = new ArrayList<>();
            for (int i=0;i<vehicleIds.length;i++){
                ResVehicleVerifyStatus status=new ResVehicleVerifyStatus();
                ResVehicleVerifyRecord record=new ResVehicleVerifyRecord();
                status.setVehicleId(vehicleIds[i]);
                record.setVehicleId(vehicleIds[i]);
                listStatus.add(status);
                listRecord.add(record);
            }
            try{
                statusMapper.updateByVehicleIds(listStatus);
                recordMapper.updateByVehicleIds(listRecord);
                return Response.genResult("撤销成功");
            }catch (Exception e){
                e.printStackTrace();
                TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
                return Response.genError("撤销失败");
            }
        }
        return Response.genError("车辆信息不能为空");
    }

1. @Transactional

2. @Transactional搭配TransactionAspectSupport.currentTransactionStatus().setRollbackOnly()
