org.apache.poi.POIXMLException：使用Libre Office更新.xls文件后POI API中的java.lang.reflect.InvocationTargetException
我正在阅读使用POI API的Excel，我使用下面的代码来阅读Excel文件。
public class ExcelWorkBook { private static ExcelWorkBook excelWorkBook = null; private static String filePath; private static XSSFWorkbook workbook; /** * This constructor used to initialize the {@link ExcelWorkBook} * @throws IOException */ private ExcelWorkBook() throws IOException { try { workbook = new XSSFWorkbook(getFile()); } catch (FileNotFoundException ex) { Logger.getLogger(ExcelWorkBook.class.getName()).log(Level.SEVERE, null, ex); } } /** * This method create a new object {@link ExcelWorkBook} * @return {@link ExcelWorkBook} * @throws IOException */ public static ExcelWorkBook getInstance() throws IOException { excelWorkBook = new ExcelWorkBook(); return excelWorkBook; } /** * This method create a {@link FileInputStream} * @return {@link FileInputStream} * @throws FileNotFoundException */ private FileInputStream getFile() throws FileNotFoundException { FileInputStream file = new FileInputStream(new File(filePath)); return file; } . . . . 但是，在使用MS Office 2010创build的特定文件中抛出以下exception，并且未使用Libre办公室。 可能是什么问题呢。 exception的堆栈跟踪如下所示

在我用Libe Office编辑一个包含注释的.xlsx文件之后，我遇到了完全相同的exception。 删除评论解决了这个问题。
您的Excel将首先被parsing成XML。 这个exception发生在xml无效时。 当您使用Microsoft Office创buildExcel工作表，然后使用Libre或Open Office等其他软件编辑工作表时，可能会出现这种情况。
我不知道Open Office或Libre Office是做什么的，但是他们对POI不喜欢的文档做了些什么。
使用Microsoft Excel来阅读或编辑您的工作表。 它不幸的为我工作。
我已经在项目中插入了org.apache.xmlbeans。 它帮助。
