批处理异常问题

ibatis 批处理唯一性异常，执行到事务结束。

循环第二次执行批处理时会将表锁死。

SqlMapClient smc = this.getSqlMapClient();
        int index = 0;
        try {
            smc.startTransaction();
            smc.startBatch();
            
            TCuBillfileChecks check = new TCuBillfileChecks();
            check.setTaskname(taskName);
            for (int i = 0; i < recordList.size(); i++) {
                Record record = recordList.get(i);
                Object    custInfo = pojoFactory.generatePojo(taskName, billMonth, record);
                smc.insert(taskName + ".insert_custinfo", custInfo);
                if (index ++ > batchNum) {// 记录断点
                    check.setBillname(record.getAttribute("Source_FileName"));
                    check.setFilenum(Integer.parseInt(record.getAttribute("RowNum")));
                    smc.update("T_CU_BILLFILE_CHECKS.updateByPrimaryKey", check);
                    smc.executeBatch();
                    index = 0;
                }
            }

            check.setBillname(recordList.get(recordList.size() - 1).getAttribute("Source_FileName"));
            check.setFilenum(Integer.parseInt(recordList.get(recordList.size() - 1).getAttribute("RowNum")));
            smc.update("T_CU_BILLFILE_CHECKS.updateByPrimaryKey", check);
            smc.executeBatch();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                smc.commitTransaction();
                smc.endTransaction();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
