java - 读取 .xls 和 .xlsx 格式的 excel 文件时出现 jxl.read.biff.BiffException 异常

Question

使用下面的代码，我得到jxl.read.biff.BiffException:无法识别OLE流。我想使用 .xls 和 .xlsx 格式文件。怎么解决这个问题？

Service.java

@Override
public boolean facultyDump(String path, HttpSession httpSession) {
    Session session=sessionFactory.openSession();
    session.beginTransaction();
    File inputWorkbook = new File(path);
    Workbook w;
    try{
        w = Workbook.getWorkbook(inputWorkbook);
        Sheet sheet = w.getSheet(0);
        for (int i = 1; i < sheet.getRows(); i++) {
            for (int j = 0; j < sheet.getColumns(); j++) {
                Cell cell = sheet.getCell(j, i);
                if (j == 0) {
                    String name= cell.getContents().trim();
                } 
            }
        }
    }catch(Exception ex){
        ex.printStackTrace();
    }finally{
        session.close();sessionFactory.close();
    }
    return false;
}

控制台异常:
