Invalid column index (256). Allowable column range for BIFF8 is (0..255) or (‘A‘..‘IV‘)异常，处理方法记录

问题出现原因
HSSFWorkbook对于单元格提供下拉选项的个数限制了255长度问题，这个时候可以使用XSSFWorkbook并把候选项以列显示可以解决了
解决代码
//导出execelpublic void exportComboxExcel(OutputStream fos) {try {workbook = new XSSFWorkbook();//excel文件对象XSSFSheet sheet1 = workbook.createSheet("sheet1");//工作表对象//设置列头样式 this.setTitleCellStyles(workbook, sheet1);//设置数据样式 this.setDataCellStyles(workbook, sheet1);//创建一个隐藏页和隐藏数据集 List<Map<String, Object>> list = createHideSheet();//创建一行列头数据 this.creatAppRowHead(sheet1, 1);//创建一行数据 for (int i = 2; i < 3; i++) {//this.creatAppRow(sheet1, i, i);this.creatAppRow(sheet1, i, i, 0,list);}workbook.write(fos);fos.flush();fos.close();} catch (FileNotFoundException e) {log.error(e.getMessage(), e);} catch (IOException e) {log.error(e.getMessage(), e);}}
//execel头信息public void creatAppRowHead(XSSFSheet userinfosheet1, int naturalRowIndex) {XSSFRow row = userinfosheet1.createRow(naturalRowIndex - 1);//0.字段名XSSFCell usernameCell = row.createCell(0);usernameCell.setCellValue("字段名");usernameCell.setCellStyle(titleStyle);//1.字段名XSSFCell loginidCell = row.createCell(1);loginidCell.setCellValue("字段名");loginidCell.setCellStyle(titleStyle);//2.字段名 XSSFCell titleTimeCell = row.createCell(2);titleTimeCell.setCellValue("字段名");titleTimeCell.setCellStyle(titleStyle);//3.字段名XSSFCell mobilCell = row.createCell(3);mobilCell.setCellValue("字段名");mobilCell.setCellStyle(titleStyle);//4.字段名XSSFCell emailCell = row.createCell(4);emailCell.setCellValue("字段名");emailCell.setCellStyle(titleStyle);//5.字段名XSSFCell orgCell = row.createCell(5);orgCell.setCellValue("字段名");orgCell.setCellStyle(titleStyle);//6.字段名XSSFCell roleCell = row.createCell(6);roleCell.setCellValue("字段名");roleCell.setCellStyle(titleStyle);//7.字段名XSSFCell areaCell = row.createCell(7);areaCell.setCellValue("字段名");areaCell.setCellStyle(titleStyle);//8.字段名XSSFCell vipCell = row.createCell(8);vipCell.setCellValue("字段名");vipCell.setCellStyle(titleStyle);//9 字段名XSSFCell wxCell = row.createCell(9);wxCell.setCellValue("字段名");wxCell.setCellStyle(titleStyle);//9 字段名XSSFCell qqCell = row.createCell(10);qqCell.setCellValue("字段名");qqCell.setCellStyle(titleStyle);//9 字段名XSSFCell idCardCell = row.createCell(11);idCardCell.setCellValue("字段名");idCardCell.setCellStyle(titleStyle);//10.字段名XSSFCell personTypeCell = row.createCell(12);personTypeCell.setCellValue("字段名");personTypeCell.setCellStyle(titleStyle);}
