mybatis批处理解决事务超时问题

        // 获取sqlSession工厂，sqlSessionFactory是配置文件中配置的数据库连接bean
        SqlSessionFactory sqlSessionFactory = SpringContextHolder.getBean("sqlSessionFactory");
        // 获取批处理数据源，false表示手动提交事务
        SqlSession sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH, false);
        try {
            // 获取需要批处理的mapper
            FundFlowDAO fundFlowDAO = sqlSession.getMapper(FundFlowDAO.class);
            // 批量处理集合
            fundFlowDAO.batchInsertFundFlow(insertFundFlowList);
            sqlSession.commit();
        } catch (Throwable e) {
            LogUtil.error(logger, e.toString());
            sqlSession.rollback();
        } finally {
            if (sqlSession != null) {
                sqlSession.close();
            }
            LogUtil.info(logger, "endTime===" + (System.currentTimeMillis() - startTime) / 1000);
        }
