1、导入Execl数据时提示错误,如下图

    

2、操作步骤

  因无法确定.xls和.xlsx哪种格式系统支持,新建表格用了.xlsx格式,后发现系统找不到该格式,直接把文件名的后缀改成了.xls。

3、关键问题的原因还是excel版本的问题

  解决办法

    a. 判断文件后缀名是xls,还是xlsx;HSSFWorkbook:是操作Excel2003以前(包括2003)的版本,扩展名是.xls;XSSFWorkbook:是操作Excel2007的版本,扩展名是.xlsx。

    b. 如果是xls,使用HSSFWorkbook;如果是xlsx,使用XSSFWorkbook。
