读入Excel报jxl.read.biff.BiffException: Unable to recognize OLE stream



最近遇到的一个问题，从系统中导出Excle后，修改excel的某些字段内容，然后再导入Excel,通过jxl读取Excel,出现jxl读文件异常

jxl.read.biff.BiffException: Unable to recognize OLE stream
    at jxl.read.biff.CompoundFile.<init>(CompoundFile.java:116)
    at jxl.read.biff.File.<init>(File.java:127)
    at jxl.Workbook.getWorkbook(Workbook.java:221)
    at jxl.Workbook.getWorkbook(Workbook.java:198)

jxl.read.biff.BiffException: Unable to recognize OLE stream    
    at jxl.read.biff.CompoundFile.<init>(CompoundFile.java:116)    
    at jxl.read.biff.File.<init>(File.java:127)    
    at jxl.Workbook.getWorkbook(Workbook.java:221)    
    at jxl.Workbook.getWorkbook(Workbook.java:198)  

 说明导入的excel不是jxl认定的标准的OLE file，可是打开的看起来是Excle，然后我把这个Excel重新另存为一个Excel,发现他默认的保存类型是“单个文件网页”（通过EditPlus打开Excle可以看到是网页文件），然后把他保类型修改为Microsoft Office Excel，保存导入，就可以正确导入了。

另外一个可能的原因是：excel的版本问题

 

但是也可以不是通过另存为的方式，来进行导入。

 

1、读入Excel是按文本方式读入

2、导出Excel，按照符合jxl的方式导出

 

public void outPutExcel(List<InvoiceRequisitionSo> result,HttpServletResponse response ){
    OutputStream os = null;
    try{
        os = response.getOutputStream();
    }catch (IOException el){

    }
    response.reset();
    response.setHeader("Content-disposition", "attachment; filename=InvoiceRequisitionListToExcel.xls");
    response.setContentType("application/msexcel");
    WritableWorkbook wwb=null;
    WritableSheet ws=null;
    WritableCellFormat cellFormat = new WritableCellFormat();
    WritableCellFormat cellFormatContent = new WritableCellFormat();
    WritableFont font= new WritableFont(WritableFont.createFont("宋体"),10, WritableFont.NO_BOLD);
    WritableFont font1= new WritableFont(WritableFont.createFont("宋体"),10, WritableFont.NO_BOLD);
    try{
       wwb = Workbook.createWorkbook(os);
       ws = wwb.createSheet("总部发票申请", 0);
       font.setColour(Colour.WHITE);
       WritableCellFormat cellFormatContentt = new WritableCellFormat(font);
       font1.setColour(Colour.RED);
       WritableCellFormat cellFormatContentred = new WritableCellFormat(font1);
       ws.getSettings().setDefaultColumnWidth(18);
       //设置单元格格式
     cellFormat.setBackground(Colour.GRAY_25);
       cellFormat.setBorder(Border.ALL, BorderLineStyle.THIN, Colour.BLACK);
       cellFormatContent.setBorder(Border.ALL, BorderLineStyle.THIN, Colour.BLACK);
       cellFormatContentt.setBorder(Border.ALL, BorderLineStyle.THIN, Colour.BLACK);
       int i = 0;
       for (InvoiceRequisitionSo so : result) {
             ws.addCell(new Label(0,i,so.getInvoice(),cellFormatContentred ));
              //合并单元格
         ws.mergeCells(1, i , 2, i );
              ws.addCell(new Label(1, i, so.getEno(), cellFormatContent));
              i++;
      }
    }catch (Exception e){

    } finally{
            try {
                wwb.write();
                wwb.close();
                os.close();
            } catch (Exception e) {

            }
        }
}
