乐橙播放视频需要插件，如何让用户直接下载插件

乐橙视频播放需要插件，所以如果没有插件为了让用户直接下载插件！

首先给个下载链接( • ̀ω•́ )✧

然后是controller٩(๑❛ᴗ❛๑)۶

 @RequestMapping("你的名字")
  public void download(HttpServletRequest request, HttpServletResponse response) throws IOException {
   response.setCharacterEncoding("UTF-8"); 
  //设置ContentType字段值  
  response.setContentType("text/html;charset=utf-8"); 
  //获取所要下载的文件名称  
  String filename = request.getParameter("filename"); 
  //************下载文件所在目录   路径始终不对后来获取Web项目的全路径
  String folder = request.getServletContext().getRealPath("/")+"statics/plug-in/IE/"; 
  //通知浏览器以下载的方式打开  
  response.addHeader("Content-type", "appllication/octet-stream"); 
  response.addHeader("Content-Disposition", "attachment;filename="+filename); 
  //通知文件流读取文件  
  InputStream inputStream = new FileInputStream(folder+filename); 
  System.out.println(folder+filename);
  //获取response对象的输出流  
  OutputStream out = response.getOutputStream();
  byte[] buffer = new byte[1024]; 
  int count = 0;
  //循环取出流中的数据  
  while ((count = inputStream.read(buffer)) != -1) {
 out.write(buffer, 0, count);
  } 
  out.close();
 out.flush();
  }

最后就大功告成啦~~(oﾟ▽ﾟ)o
