		XSSFSheet spreadsheet = workbook.createSheet("Sheet Name");
		String[] strs = new String[]{"aa","bb","cc","dd","ee","ff","gg","hh","ii"};

		DataValidationConstraint createExplicitListConstraint = dataValidationHelper.createExplicitListConstraint(strs);
		DataValidation createValidation = dataValidationHelper.createValidation(createExplicitListConstraint, regions);
	     //处理Excel兼容性问题
        if (createValidation instanceof XSSFDataValidation) {
            createValidation.setSuppressDropDownArrow(true);
            createValidation.setShowErrorBox(true);
        } else {
            createValidation.setSuppressDropDownArrow(false);
        }
        spreadsheet.addValidationData(createValidation);
		FileOutputStream out = new FileOutputStream( new File("D:/Writesheet.xlsx"));
		workbook.write(out);
		out.close();
