如何解决JXL错误:JXL.read.biff.BiffException:无法识别OLE流

我试图从.csv文件中获取单元格数据，但出现错误：jxl.read.biff.BiffException：无法识别OLE流

我不知道如何解决这个问题，请给我一些解决方案这段代码是为jxlapi&这是对.csv的api支持吗？

参考代码：

public void read() throws IOException, BiffException  {
    File inputWorkbook = new File(inputFile);
    try
    {
        w = Workbook.getWorkbook(inputWorkbook.getAbsoluteFile());
        // Get the first sheet
        Sheet sheet = w.getSheet(0);
        // Loop over first 10 column and lines
        for (row = 1; row < sheet.getRows(); row++) 
        {
            ReadExcelLotSizeEntity readExcelLotSizeEntity =new ReadExcelLotSizeEntity();
                cell = sheet.getCell(1,row);
                type= cell.getType();
                if (cell.getType() == CellType.LABEL)
                {
                    symbol=cell.getContents();
                    System.out.println(":::::::::::::::::"+symbol);
                    readExcelLotSizeEntity.setSymbol(symbol);
                }   
                int col=2;
                cell = sheet.getCell(col,row);
                while(!cell.getContents().equals("")||cell.getContents()!=null)
                {
                    System.out.println("||||||||||||||||"+cell.getContents());
                    cell=sheet.getCell(col,row);
                    col++;
                }
                lotSize= new Double(cell.getContents());
                readExcelLotSizeEntity.setLotSize(lotSize);
                readExcelLotSizeEntity.setCreateUserId(1L);
                readExcelLotSizeEntity.setCreateDtTm(new Date());
                readExcelLotSizeHome.persist(readExcelLotSizeEntity);
            }
    } catch (BiffException e) {
        e.printStackTrace();
    }
}
