H5播放音乐中途停止

[ryelqy]

用ServeltOutputStream输出音乐文件，H5前台可以播放音乐，但整首歌曲4分钟，只能播放53秒，然后就停止了。
求播放完整方法。

控制台日志：

信息: A cookie header was received [1500479053] that contained an invalid cookie. That cookie will be ignored.Note: further occurrences of this error will be logged at DEBUG level.

前台代码：

<audio id="mp3" src="Test/video.do" autoplay="true" controls="true" loop="true">

后台代码：

@RequestMapping("/video.do")
	public @ResponseBody void video(String id, HttpServletRequest request, HttpServletResponse response)throws Exception{
		File file = new File("E:/1.mp3");
		FileInputStream in = new FileInputStream(file);
		BufferedInputStream bin = new BufferedInputStream(in);
		ServletOutputStream out = response.getOutputStream();
		byte[] b = null;
		while(bin.available() >0) {
			if(bin.available()>102400) {
				b = new byte[102400];
			}else {
				b = new byte[bin.available()];
			}
			bin.read(b, 0, b.length);
			out.write(b, 0, b.length);
		}
		b = new byte[bin.available()];
		bin.read(b);
		out.write(b);
		in.close();
		out.flush();
		out.close();
	}

response 头设置信息不足，需要设置媒体类型，文件长度等 102400不是一个好的长度，最好取2的整数次幂，4k，8k，32k等（K=1024）
