mybatis 分批次手动提交事务

@Autowired private SqlSessionFactory sqlSessionFactory; public boolean saveOrUpdateStockBatch(List<SaleStockPO> entityList, int batchSize, StockOperationTypeEnum operationTypeEnum) { // 此种提交方法，会导致新增后主键无法回显，暂时废弃 SqlSession session = sqlSessionFactory.openSession(ExecutorType.BATCH, false); SaleStockDAO mapper = session.getMapper(SaleStockDAO.class); try { if (entityList.size() <= batchSize) { executeStock(operationTypeEnum, mapper, entityList); } else { List<SaleStockPO> list = Lists.newArrayList(); for (int i = 0; i < entityList.size(); i++) { list.add(entityList.get(i)); if (i >= 1 && i % batchSize == 0) { executeStock(operationTypeEnum, mapper, list); session.commit(); session.clearCache(); list.clear(); } } if (CollectionUtil.isNotEmpty(list)) { executeStock(operationTypeEnum, mapper, list); } } session.commit(); session.clearCache(); } catch (Exception e) { logger.error(CharConstant.ERROR, e); session.rollback(); ExceptionUtils.throwServiceException(ErrorCodeConstant.STOCK_UPDATE_FAIL); } finally { session.close(); } return true; private void executeStock(StockOperationTypeEnum operationTypeEnum, SaleStockDAO mapper, List<SaleStockPO> list) { mapper.batchInsertIgnore(list); }
