Question

作家班结束后。弹簧批处理执行中发生错误。所有读取数据都要回滚，而块数据不会插入数据库。

在步骤执行数据已更新时，提交失败的含义是什么错误＆＃34;？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（注释到＆＃39; recordDataService.insertRecordData（recordData）;＆＃39;，则没有问题。

我的代码：

    @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);
    }

彼此作家的日志：
