Java批量插入数据的代码实现

@Override

            dataLogList.add(filterLogEntity.get(i));
            if (i > 0 && i % nums == 0 || i == filterLogEntity.size() - 1) {
                filterOraMapper.insertData(dataLogList);
                //每次插入完数据，将上次存储的100条数据清空
                dataLogList.clear();
            }
        }
