读取excel文件内容

    try {
        // 创建工作簿
        XSSFWorkbook xssfWorkbook = new XSSFWorkbook(new FileInputStream("E:\\test.xlsx"));
        System.out.println("Workbook对象：" + xssfWorkbook);
        // 读取第一个工作表
        XSSFSheet sheet = xssfWorkbook.getSheetAt(0);
        System.out.println("sheet对象：" + sheet);
        // 获取最后一行的num，即总行数。此处从0开始计数
        int maxRow = sheet.getLastRowNum();
        System.out.println("总行数为：" + (maxRow + 1));
        for (int row = 0; row <= maxRow; row++) {
            for (int cell = 0; cell <= sheet.getRow(row).getLastCellNum() - 1; cell++) {
                //row代表行  cell代表列
                System.out.print(sheet.getRow(row).getCell(cell) + " ");
            }
            System.out.println();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
