我在上传 excel 文件时遇到问题，下面是我的 Java 代码

File newFile = new File("C:/sample.xls");
int firstColNo = 0;
int row = 0;
Cell cell;
Workbook wb = Workbook.getWorkbook(newFile);
Sheet sheet = wb.getSheet(0);
    for (row = 1; row < 1005; row++) {
        LabelCell labelCell1 = sheet.findLabelCell("COMPOUND_ID");
            if (labelCell1 != null) {
                firstColNo = labelCell1.getColumn();
                cell = sheet.getCell(firstColNo, row);
                    if (cell.getContents() != null && cell.getContents().length() > 0) {                                            System.out.println(cell.getContents());
                } else {
                                        System.out.println("-");
                                    }
                                }
                            }

当我调试它时，我得到了这个异常

jxl.read.biff.BiffException: Unable to recognize OLE stream

我正在使用 jxl.jar 文件进行文件上传。

谁能帮我解决它？

在堆栈跟踪上它是

at jxl.Workbook.getWorkbook(Workbook.java:198)

在您的代码中调用

Workbook wb = Workbook.getWorkbook(newFile);

我使用过 POI 和其他 excel 库，而不是 this ，但似乎在这一点上可以将 FileNotFoundException 转换为 jxl.read.biff.BiffException 或者库无法识别输入文件格式。-因为你给了一个普通的.txt 重命名为 .xls

请至少进行 Java 级别的验证

if(!newFile.isFile()){
    return;
}

你也可以检查长度不为0等等。

也许这可以成为您的解决方案。

我希望它可以帮助您找到方向。
