我通过 sftp 接收此文件，并将其作为字符串读取，获取其内容。我尝试使用 Apache POI，认为我可以将其作为 xls 文件读取并将其映射到一个类。

这是我试图阅读它的方式：

   private void processFileData(String stringData, String filename, String extension)
    {
        InputStream inp = IOUtils.toInputStream(stringData, StandardCharsets.UTF_8);
        List<MULSite> siteList = new ArrayList<MULSite>();

        try {
            inp = FileMagic.prepareToCheckMagic(inp);
            Workbook workbook = WorkbookFactory.create(inp);
            Iterator<Row> iterator = workbook.getSheet("SITES_INFO").iterator();
            while (iterator.hasNext())
            {
                MULSite site = new MULSite();
                site.parse(iterator.next(),"xls", filename);
                DtoValidatorResult isValid = site.validate();
                if(isValid.getValid())
                {
                    splittableDtoMap.put(site.getSiteNumber(), site.toString());
                }
                else {
                    throw new RetrieverException("Issue encountered at " + filename);
                }
            }
        } catch (IOException | RetrieverException | JAXBException e) {
            e.printStackTrace();
        }
    }

但是当它到达：Workbook workbook = WorkbookFactory.create(inp); 时会抛出以下错误：java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream

我对如何处理这种类型的文件有点困惑，我尝试将扩展名从 .xml 更改为 .xls，Excel 可以两种方式完美打开它，但 Apache POI 不接受它，我不确定是否有问题是与文件或我如何使用 InputStream 读取它。

【问题讨论】：

  • 不确定，但我认为this 回答您的问题

标签： java xml apache-poi


【解决方案1】：

遗憾的是这是不可能的，Apache POI 不支持 Office XML，它从未在库中实现，因为微软很快就弃用了它。

我已经放弃尝试使用 Apache POI 进行此操作，并将使用 XML 解析器将其解析为 DOM。
