Question

我想使用Apache POI从excel表中存储数据。

在该excel中，第一行包含员工信息（即员工姓名），列值包含员工详细信息（即员工地址）。
因此每个标题行（emp名称）由多列（emp地址）组成

如何获取存储在单个实体中的行和列值？

我正在使用Java Spring数据。

假设您正在使用弹簧注释，则可以使用以下代码从Excel工作表中读取值。

  @RequestMapping(value = "/excelSheetProgram")
            public String excelSheetProgram(@ModelAttribute("excel"),
                    HttpServletRequest request, RedirectAttributes attributes, HttpServletResponse response, Object command,
                    BindException errors, @RequestParam("Excelfile") MultipartFile Excelfile) throws Exception {

            InputStream inputStream = null;
            inputStream = Excelfile.getInputStream();

            XSSFWorkbook workbook = new XSSFWorkbook(new 
            PushbackInputStream(inputStream));
            XSSFSheet mySheet = workbook.getSheetAt(0);

    // boolean variable for checking when to stop execution of reading from excel fields
            boolean inData = true;

    Iterator<Row> rowIterator = mySheet.iterator();
        rowIterator.next();
        int count = 0;
        for (int i = 0; rowIterator.hasNext() && inData; i++) {
            count++;

            Row row = rowIterator.next();



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

        while (cellIterator.hasNext()) {
            Cell cell = cellIterator.next();

            // This will change all Cell Types to String
            cell.setCellType(Cell.CELL_TYPE_STRING);
            switch (cell.getCellType()) {
            case Cell.CELL_TYPE_BOOLEAN:

                break;
            case Cell.CELL_TYPE_NUMERIC:

                break;
            case Cell.CELL_TYPE_STRING:



                break;
            }

        }

if (row == null || row.getCell(1) == null || row.getCell(1).getStringCellValue() == null
                    || inData == false) {
                inData = false;
            } 
            else {

                // getting values from excel cells
                employee_name = row.getCell(0).getStringCellValue();
                employee_address = row.getCell(1).getStringCellValue();
    }
}
