读取execl数据

public static void main(String[] args) throws IOException {

    FileInputStream fileInput = new FileInputStream("C:\Users\DELL4\Desktop\567.xlsx");//创建文件输入流
    XSSFWorkbook wb = new XSSFWorkbook(fileInput);//由输入流文件得到工作簿对象
    XSSFSheet sheet = wb.getSheetAt(0);//获取第一个sheet
    int lastRowNum = sheet.getLastRowNum(); //获取表格内容的最后一行的行数

    //rowBegin代表要开始读取的行号，下面这个循环的作用是读取每一行内容
    for (int i = 1; i <= lastRowNum; ++i) {
        XSSFRow row = sheet.getRow(i);//获取每一行
        int columnNum = row.getLastCellNum();//获取每一行的最后一列的列号，即总列数
        for (int j = 1; j < columnNum; ++j) {
            XSSFCell cell = row.getCell(j);//获取每个单元格
            if (CellType.NUMERIC.equals(cell.getCellTypeEnum())) {
                System.out.printf("%.0f	", cell.getNumericCellValue());
            } else {
                System.out.printf("%s	", cell.getStringCellValue());
            }
        }
        System.out.println();
    }
    wb.close();
    fileInput.close();
