閱讀.xlsx文件給出的InvocationTargetException

Question

我想讀使用Apache POI .xlsx文件，但錯誤我擊中：錯誤的

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

完整堆棧跟蹤說：

PS：我提到了this和this的問題，但沒有幫助。

我也試過添加org.apache.xmlbeans罐子，但沒有運氣。

找到了答案。不是一個確切的解決方案，但工作
我的代碼沒有錯，因爲我試着閱讀其他的excel，它的工作完美無瑕。問題在於excel。
可能的原因： 首先將excel解析爲XML，當XML無效時會出現此錯誤。我的excel主要是使用MS-Office（Windows環境）開發的，我使用Libra Calc（在Linux環境下）編輯它，所以這可能是poi無法正確讀取excel的原因。
解決方案：剛剛在Linux環境下開發出了同樣的excel，因爲它運行良好。
