private void handleExcelDown (String fileName,List<RookieIe> list,String[] title,HttpServletResponse resp,boolean isSearch){
		Workbook workbook = new SXSSFWorkbook();
		Sheet sheet = workbook.createSheet("Sheet");
		Row titleRow = sheet.createRow(0);

		resp.setContentType("application/vnd.ms-excel;charset=utf-8");

		OutputStream out = null;
		try

			out = resp.getOutputStream();
			workbook.write(out);
			workbook.close();
			out.flush();
		} catch (IOException e)
		{
			e.printStackTrace();
		}finally{
			if(out!=null){
				try

前端访问方式:

downButtonFunc:function(searchText){//下載回調函數,searchText用戶的搜索字符串
	    			window.location = "../ie/allready_for_assessment_down.do?searchText="+encodeURIComponent(searchText);
	    		}

encodeURIComponent（）用于解决特殊字符的问题,url中不允许出现某些特定字符,所以需要转换
