我正在使用org.apache.poi 3.15读取一个excel文件（文件扩展名为xlsx）。

这是我的代码：

try (FileInputStream fileInputStream = new FileInputStream(file); XSSFWorkbook workbook = new XSSFWorkbook(file)) {
    XSSFSheet sheet = workbook.getSheetAt(0);
    Iterator<Row> rowIterator = sheet.iterator();
    while (rowIterator.hasNext()) {
        Row row = rowIterator.next();

        Iterator<Cell> cellIterator = row.cellIterator();
        while (cellIterator.hasNext()) {
            Cell cell = cellIterator.next();
            switch (cell.getCellType()) {
                case Cell.CELL_TYPE_NUMERIC:
                    System.out.print(cell.getNumericCellValue() + "(Integer)\t");
                    break;
                case Cell.CELL_TYPE_STRING:
                    System.out.print(cell.getStringCellValue() + "(String)\t");
                    break;
            }
        }
        System.out.println("");
    }
} catch (Exception e) {
    e.printStackTrace();
}

我收到cell.getCellType()不推荐使用的警告。谁能告诉我替代方法？
