1.第三种方法直接上代码，这里还是用的spring mvc进行的请求，主要看代码注解，代码如下：

@RequestMapping(value = "/exportComwithdrawalList",method=RequestMethod.POST)
        public void exportComwithdrawalList(
                HttpServletRequest request,
                HttpServletResponse response,
                String startTime,
                String endTime,
                String communityName,
                String processingmark) throws UnsupportedEncodingException {
    
            log.info("comwithdrawals/selectComwithdrawalList start");
            ComWithdrawalsVo comWithdrawalsVo= new ComWithdrawalsVo();
            comWithdrawalsVo.setStartTime(startTime);
            comWithdrawalsVo.setEndTime(endTime);
            comWithdrawalsVo.setCommunityName(communityName);
            comWithdrawalsVo.setProcessingMark(processingmark);
            // 获取数据列表
            List<ComWithdrawalsVo> comwithdrawalList = this.comWithdrawalsService.selectComwithdrawalList(comWithdrawalsVo);
            log.info("rechargeService.selectRechargeList end");
    
            log.info("excel导出开始 start");
            HSSFWorkbook wb = new HSSFWorkbook();
            try{

//设置request编码和类型
                request.setCharacterEncoding("UTF-8");
                response.setContentType("application/x-download");
    
                String filedisplay = "社区提现记录.xls";//为excel起名字
    
                filedisplay = URLEncoder.encode(filedisplay, "UTF-8");
                response.addHeader("Content-Disposition", "attachment;filename="+ filedisplay);//创建excel文件
    
                // 第二步，在webbook中添加一个sheet,对应Excel文件中的sheet
                HSSFSheet sheet = wb.createSheet("社区提现记录");
                // 第三步，在sheet中添加表头第0行,注意老版本poi对Excel的行数列数有限制short
                HSSFRow row = sheet.createRow((int) 0);
                // 第四步，创建单元格，并设置值表头 设置表头居中
                HSSFCellStyle style = wb.createCellStyle();
                style.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 创建一个居中格式
    
                HSSFCell cell = row.createCell( 0);
                cell.setCellValue("社区名称");
                cell.setCellStyle(style);
                sheet.setColumnWidth(0, (25 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(1);
                cell.setCellValue("提现金额");
                cell.setCellStyle(style);
                sheet.setColumnWidth(1, (20 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(2);
                cell.setCellValue("申请时间");
                cell.setCellStyle(style);
                sheet.setColumnWidth(2, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(3);
                cell.setCellValue("汇款时间");
                cell.setCellStyle(style);
                sheet.setColumnWidth(3, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(4);
                cell.setCellValue("交易流水号");
                cell.setCellStyle(style);
                sheet.setColumnWidth(4, (80 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(5);
                cell.setCellValue("回单图片");
                cell.setCellStyle(style);
                sheet.setColumnWidth(5, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(6);
                cell.setCellValue("备注");
                cell.setCellStyle(style);
                sheet.setColumnWidth(6, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(7);
                cell.setCellValue("状态");
                cell.setCellStyle(style);
                sheet.setColumnWidth(7, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(8);
                cell.setCellValue("银行卡号");
                cell.setCellStyle(style);
                sheet.setColumnWidth(8, (60 * 256));  //设置列宽
    
                cell = row.createCell(9);
                cell.setCellValue("持卡人姓名");
                cell.setCellStyle(style);
                sheet.setColumnWidth(9, (15 * 256));  //设置列宽，50个字符宽
    
                cell = row.createCell(10);
                cell.setCellValue("开户银行");

                // 第五步，写入实体数据 实际应用中这些数据从数据库得到，
                    int index = 1;
                    if(comwithdrawalList != null && comwithdrawalList.size() > 0){
                        for (int i = 0; i < comwithdrawalList.size(); i++)
                        {
                            ComWithdrawalsVo comWithdrawalsVo2 = comwithdrawalList.get(i);
                            // 第四步，创建单元格，并设置值
                            row = sheet.createRow(i+1);
                            row.createCell(0, HSSFCell.CELL_TYPE_STRING).setCellValue(comWithdrawalsVo2.getCommunityName());//社区名称
                            row.createCell(1, HSSFCell.CELL_TYPE_STRING).setCellValue(comWithdrawalsVo2.getReflectMoney());//提现金额
                            row.createCell(2, HSSFCell.CELL_TYPE_STRING).setCellValue(comWithdrawalsVo2.getApplicationTimeStr());   //申请时间
                            row.createCell(3, HSSFCell.CELL_TYPE_STRING).setCellValue(comWithdrawalsVo2.getPaymentTimeStr());  //汇款时间

                        }
                    }
                // 第六步，将文件存到指定位置
                OutputStream out = response.getOutputStream();
                wb.write(out);
                out.close();
    
            }catch (Exception ex){
                ex.printStackTrace();
            }
        }

至此，代码结束。
