java服务器下载文件浏览器无反应

用google浏览器作的测试
需求:
将指定内容以文件流的形式下载

代码:

@RequestMapping("saveSort")
    public void saveSort(String[] id, HttpServletResponse response){
        if (ArrayUtils.isNotEmpty(id)){
            OutputStream out = null;
            try {
                String formatdata = tvSourceService.createConfigLine(id);
                if (StringUtils.isBlank(formatdata)){
                    return ;
                }
                //下载
                String fileName ="IPTV.txt";
                response.reset();
                response.setHeader("Content-Disposition","attachment; fileName="+URLEncoder.encode(fileName,"UTF-8"));
//                response.setHeader("Cache-Control","max-age=0");
                response.setContentType("multipart/form-data");
                response.setCharacterEncoding("UTF-8");

                out = response.getOutputStream();
                out.write(formatdata.getBytes("UTF-8"));
                out.flush();
                out.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

原因：
浏览器的下载插件影响（如迅雷）

解决：
方法1：停用浏览器下载插件
方法2：重置浏览器设置，见[url=http://jingyan.baidu.com/album/c33e3f48a1445fea15cbb537.html?picindex=1]百度经验[/url]
