第二版，依然存在IE11多次导出文件后缀名是.action的问题，待进一步解决：
	List<Object> list=treeService.getExportStationWaterQualityData(stcd, startTm, endTm);
		if (null!=list&&list.size()>0) {
		List<Map<String,String>> factorList = (List<Map<String,String>>)list.get(0);//表头因子项
		List<Object[]> ItemList=(List<Object[]>)list.get(1);//数据项
		List<Object[]> ItemStyleList=(List<Object[]>)list.get(2);//样式项
		  // 
		  HttpServletRequest request = ServletActionContext.getRequest();
		  HttpServletResponse response=ServletActionContext.getResponse();
		  response.reset();
		  try {
		   HSSFWorkbook workbook = new HSSFWorkbook();   
		   HSSFSheet sheet = workbook.createSheet("Sheet1");   
		   //title
		   HSSFCellStyle cellStyleMiddleTitle = workbook.createCellStyle();   
		   cellStyleMiddleTitle.setAlignment(HSSFCellStyle.ALIGN_CENTER);//字体、居中
		   HSSFFont hssfFontTitle = workbook.createFont();
		   hssfFontTitle.setFontName("微软雅黑");
		   hssfFontTitle.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//加粗
		   hssfFontTitle.setFontHeightInPoints((short)10);//
		   cellStyleMiddleTitle.setFont(hssfFontTitle);
		   //remark
		   HSSFCellStyle cellStyleMiddleRemark = workbook.createCellStyle();   
		   cellStyleMiddleRemark.setAlignment(HSSFCellStyle.ALIGN_CENTER);//居中
		   //
		   HSSFCellStyle cellStyleLeft = workbook.createCellStyle();

		   sheet.addMergedRegion(new CellRangeAddress(0, 0, (short)0, (short)sizeLen));

		   cell=row.createCell(0);
		   cell.setCellValue("采样时间");
		   cell.setCellStyle(cellStyleMiddleRemark);//居中
		   //第三行第一列后面的动态读取
		   for (int i = 0; i < factorList.size(); i++) {

					cell.setCellValue(factorList.get(i).get("name")+"("+factorList.get(i).get("sampling_unit")+")");
				}else {
					cell.setCellValue(factorList.get(i).get("name"));
				}
			  
		   }
		   //4、设置表体数据
		   //渲染数据
		   Object[] arr;
		   for (int i = 0; i < ItemList.size(); i++) {
			   arr=ItemList.get(i);//行数据准备
			   row=sheet.createRow(i+3);//增加行，第四行开始......
			   for (int j = 0; j < arr.length; j++) {
				   cell=row.createCell(j);
				   cell.setCellValue(arr[j].toString());   
			}
		    }
		   //给数据设置评估颜色
		 
		    //绿色
		   HSSFCellStyle cellStyle_Green = workbook.createCellStyle();   
		   HSSFFont hssfFont_Green = workbook.createFont();
		   hssfFont_Green.setColor(HSSFColor.GREEN.index);
		   cellStyle_Green.setFont(hssfFont_Green);

			   if (null!=obj&&obj.length>0) {
				   for (int j = 0; j < obj.length; j++) {

		   //5、设置自定义导出路径
		   response.setContentType("octets/stream");
	       String excelName = "。。。。表";
	       //转码防止乱码
	       response.addHeader("Content-Disposition", "attachment;filename="+new String( excelName.getBytes("gb2312"), "ISO8859-1" )+".xls");
		   OutputStream os = response.getOutputStream();
		   workbook.write(os);
		   os.close();
		   System.out.println("excel导出成功");
		  } catch (Exception ioexception) {   
		   request.setAttribute("message", "excel导出失败");   
		  }   
		}

下面两种写法运行效果一样，有待进一步完善：
/*
			   response.setContentType("octets/stream");
		       String excelName = "。。。报表";
		       response.addHeader("Content-Disposition", "attachment;filename="+new String( excelName.getBytes("gb2312"), "ISO8859-1" )+".xls");
			   OutputStream os = response.getOutputStream();
			   workbook.write(os);
			   os.flush();
			   os.close();
			   */
			  String excelName = "。。。报表";
		      response.setContentType("application/vnd.ms-excel");
		      response.setHeader("Content-disposition", "attachment;filename=" +new String( excelName.getBytes("gb2312"), "ISO8859-1" )+".xls");
		      OutputStream ouputStream = response.getOutputStream();
		      workbook.write(ouputStream);
		      ouputStream.flush();
		      ouputStream.close();
