作家班结束后 . spring 批处理执行中发生错误 . 所有读取数据都要回滚，而块数据不会插入到DB中 .

“步骤执行数据已更新错误时提交失败”是什么意思？为什么会出现这个日志？

是作家插入交易的时间问题吗？

如果有一次插入事务（注释掉'recordDataService.insertRecordData（recordData）;'，则没有问题 .

My Code :

@Override
    public void write(List<? extends RecordInfo> items)  {

    log.info("########################################################");
    log.info("write");
    log.info("########################################################");

    recordInfoService.insertRecordInfo(recordInfos.get(0));

    for( RecordData recordData : recordInfos.get(0).getRecordDataList()){
                recordDataService.insertRecordData(recordData);
    }
