红字部分代表mybatis的批量操作调用方法：

　　　　　　　int num = 0;

            int maxLength = 200;

            int size = usableCodes.size();

            if (size <= maxLength) {

                bean  = createBean(bean,entity,usableCodes);

                num = receiptMapper.receipt(bean);

            } else {

                // 计算循环次数

                int eachTime = (size / maxLength) + 1;

                for (int i = 0; i < eachTime; i++) {

                    int fromIndex = 0;

                    int toIndex = 0;

                    fromIndex = (i * maxLength);

                    toIndex = (fromIndex + maxLength);

                    if (i + 1 == eachTime) {

                        toIndex = usableCodes.size();

                    }

                    List<String> subList = usableCodes.subList(fromIndex, toIndex);

                    if (subList.size() > 0) {

                        bean = createBean(bean,entity,subList);

                        num += receiptMapper.receipt(bean);

                    }

                }

            }
