Question

我正在使用POI api阅读Excel，我使用以下代码来阅读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;
        }
        .
        .
        .
        .

但它在使用MS Office 2010创建的特定文件中抛出以下异常，并使用Libre office进行了未注明日期。可能是什么问题呢。异常的堆栈跟踪附在

Answer 1

在我使用Libe Office编辑包含注释的.xlsx文件后，我遇到了完全相同的异常。删除评论解决了这个问题。

Answer 2

您的Excel将首先解析为XML。当xml无效时会发生此异常。当您使用Microsoft Office创建Excel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阅读或编辑工作表。不幸的是，它对我有用。

Answer 3

我在项目中插入了org.apache.xmlbeans。它有所帮助。

org.apache.poi.POIXMLException：使用Libre Office更新.xls文件后POI API中的java.lang.reflect.InvocationTargetException
