我正要建议 AurA 的解决方案,但看起来您确实必须在运行时构建验证列表。
你应该看看POI Quick Guide,它们似乎正是你所需要的:
hssf.usermodel(二进制 .xls 格式)
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("Data Validation");
CellRangeAddressList addressList = new CellRangeAddressList(0, 0, 0, 0);
DVConstraint dvConstraint = DVConstraint.createExplicitListConstraint(new String[]{"10", "20", "30"});
DataValidation dataValidation = new HSSFDataValidation(addressList, dvConstraint);
dataValidation.setSuppressDropDownArrow(false);
sheet.addValidationData(dataValidation);
xssf.usermodel(.xlsx 格式)
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("Data Validation");
XSSFDataValidationHelper dvHelper = new XSSFDataValidationHelper(sheet);
XSSFDataValidationConstraint dvConstraint = (XSSFDataValidationConstraint)
dvHelper.createExplicitListConstraint(new String[]{"11", "21", "31"});
CellRangeAddressList addressList = new CellRangeAddressList(0, 0, 0, 0);
XSSFDataValidation validation = (XSSFDataValidation)dvHelper.createValidation(
dvConstraint, addressList);
validation.setShowErrorBox(true);
sheet.addValidationData(validation);
