参数信息不完整，前端传递参数为:app视频.mp4，在后端得到的参数值是：app视频，没有扩展名
代码：

	@At("/f/?/?")
	@Ok("raw")
	public File f(String storeFileName, String realFileName,HttpServletResponse response) {
		response.addHeader("Content-Type", "video/mp4");
		response.addHeader("Content-Disposition", "inline");
		File f = new File(attachmentSimplePath + "/" + storeFileName + "/" + realFileName);
		return f;
	}
