我们正在尝试使用apache POI读取xlsx文件。每件事情都很好。但有时当我们上传一个xlsx文件时，它会给出下面的错误。Apache POI XSSF加载问题

如果我们将相同的内容复制到另一个xlsx文件并上传它，一切工作正常。我们无法确定此错误的根本原因。感谢任何帮助/建议。
罐使用： POI-3.16.jar POI-OOXML-3.16.jar POI-OOXML-架构 - 3.16.jar
更新：
即使POI版本3.14，我们正在以下例外：

代码初始化xlsx的读取。这其中我们得到此异常：
XSSFWorkbook workbook = new XSSFWorkbook(file);
你可以试试这个'Workbook workbook = WorkbookFactory.create（file）;' –
这也给出了同样的例外。 – Manjunath
此文件从哪里来？如果您在Excel中打开该文件并执行另存为，问题是否消失？ – Gagravarr
