@Override
	public void export(HttpServletRequest request,
			HttpServletResponse response, List<Map<String, Object>> dataResult,
			String saveAsFileName) throws ServletException, UnsupportedEncodingException {
		response.setContentType("text/html;charset=utf-8");
		// 完美解决IE浏览器下载中文乱码的问题,兼容IE,Firefox,Chorme
		String agent = request.getHeader("User-Agent");
		boolean isMSIE = (agent != null && agent.indexOf("MSIE") != -1);
		String fileName = null;
		if (isMSIE) {
			fileName = URLEncoder.encode(saveAsFileName, "UTF-8");
		} else {
			fileName = new String(saveAsFileName.getBytes("UTF-8"),
					"ISO-8859-1");
		}

		BufferedOutputStream bos = null;
		try {
			byte[] data = exportReport(dataResult);
			long fileLength = data.length;
			response.addHeader("Content-Length", "" + fileLength);
			response.setContentType("application/octet-stream;charset=UTF-8");
			// response.setContentType("application/x-msdownload;");
			response.setHeader("Content-disposition", "attachment; filename="
					+ fileName + ".zip");
			response.setHeader("Content-Length", String.valueOf(fileLength));
			bos = new BufferedOutputStream(response.getOutputStream());
			bos.write(data);
			bos.flush();
		} catch (IOException e) {
