判断客户端是否为IE

public static boolean isIE(HttpServletRequest request) {
        String userAgent = request.getHeader("User-Agent").toLowerCase();
        return userAgent.contains("msie") || userAgent.contains("trident");
    }

设置让浏览器弹出下载对话框的Header

public static void setDownloadableHeader(HttpServletRequest request, HttpServletResponse response, String fileName) {
        String charsetName = "utf-8";
        if (WebUtil.isIE(request)) {
            charsetName = "gb2312";
        }
        response.setContentType("application/octet-stream");
        try {
            response.setHeader("Content-Disposition", "attachment; filename=" + new String(fileName.getBytes(charsetName), "iso8859-1"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
