使用没有标题的POI读取Excel文件

我想阅读excel文件使用poi没有标题头，我的预期结果是这样的

这是我的代码

public String processExcel(Model model, @RequestParam(value = "excelfile", required = false) MultipartFile excelfile, HttpSession session) { try { List<UserRegistrationDetail> lstUser = new ArrayList<>(); Workbook workbook = null; if (excelfile.getOriginalFilename().endsWith("xlsx")) { workbook = new XSSFWorkbook(excelfile.getInputStream()); } else if (excelfile.getOriginalFilename().endsWith("xls")) { workbook = new HSSFWorkbook(excelfile.getInputStream()); } else { model.addAttribute("msg", new IllegalArgumentException("The specified file is not Excel file")); } Sheet worksheet = workbook.getSheetAt(0); Iterator<Row> iterator = worksheet.iterator(); while (iterator.hasNext()) { Row nextRow = iterator.next(); Iterator<Cell> cellIterator = nextRow.cellIterator(); UserRegistrationDetail user = new UserRegistrationDetail(); while (cellIterator.hasNext()) { Cell nextCell = cellIterator.next(); int columnIndex = nextCell.getColumnIndex(); switch (columnIndex) { case 0: user.setId(String.valueOf(nextCell.getNumericCellValue())); break; case 1: user.setEmail(nextCell.getStringCellValue()); break; case 2: user.setFullname(nextCell.getStringCellValue()); break; } } lstUser.add(user); } model.addAttribute("listUser", lstUser); session.setAttribute("listUserImport", lstUser); } catch (Exception e) { model.addAttribute("msg", e.getMessage()); } return "reportregistrationuser"; } 

目前我的代码只能像这样读取文件excel

如何实现我的预期结果，我在做什么？

在迭代每一行之前，首先使用iterator.next()将迭代器移动到第二行。 所以在你的while循环中，它将从第二行开始。

 Iterator<Row> iterator = worksheet.iterator(); //Add the below line Row headerRow= iterator.next();
