我需要在Java中讀取xlsx文件

Question

但是我收到錯誤。 是否有任何錯誤。 File myFile = new File（“ D：/ abhilash / L2t Tracker.xlsx”）; FileInputStream fis =新的FileInputStream（myFile）;

        // Finds the workbook instance for XLSX file
        XSSFWorkbook myWorkBook = new XSSFWorkbook (fis);

        // Return first sheet from the XLSX workbook
        XSSFSheet mySheet = myWorkBook.getSheetAt(0);

        // Get iterator to all the rows in current sheet
        Iterator<Row> rowIterator = mySheet.iterator();

        // Traversing over each row of XLSX file
        while (rowIterator.hasNext()) {
            Row row = rowIterator.next();

            // For each row, iterate through each columns
            Iterator<Cell> cellIterator = row.cellIterator();
            while (cellIterator.hasNext()) {

                Cell cell = cellIterator.next();

                switch (cell.getCellType()) {
                case Cell.CELL_TYPE_STRING:
                    System.out.print(cell.getStringCellValue() + "\t");
                    break;
                case Cell.CELL_TYPE_NUMERIC:
                    System.out.print(cell.getNumericCellValue() + "\t");
                    break;
                case Cell.CELL_TYPE_BOOLEAN:
                    System.out.print(cell.getBooleanCellValue() + "\t");
                    break;
                default :

                }
            }
            System.out.println("");
        }

我得到了答案。 為此，我們還需要導入dom4j jar和poi ooxml模式。我忘記了這兩個文件
