我正在尝试使用 Apache POI 读取 .xlsx 文件，但遇到错误:

org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException

错误的完整堆栈跟踪说:

PS:我提到了this和 this问题，但没有帮助。

我也尝试添加 org.apache.xmlbeans jar，但没有成功。

Answer 1

找到了答案。不是一个确切的解决方案，但有效。
当我尝试阅读其他 excel 时，我的代码没有任何问题，并且它运行完美。问题出在excel上。
可能的原因: 首先将 excel 解析为 XML，当 XML 无效时，您会收到此错误。我的excel主要是用MS-Office(Windows环境)开发的，我用Libra Calc(Linux环境)编辑它，所以这可能是poi无法正确读取excel的原因。
解决方案:刚在linux环境下开发了同样的excel，效果不错。
