求救，打包后音乐没声音了，应该怎么改

Question

class Sound
{ 
   FileInputStream file;
   BufferedInputStream buf;
   public Sound()
{
try 
{ 
   file=new FileInputStream("./src/music/001.mid");
   buf=new BufferedInputStream(file);
   AudioStream audio=new AudioStream(buf);
   AudioPlayer.player.start(audio);
}
catch (Exception e) {}
}
}

button下的是这个Sound play = new Sound();未打包前是可以正常播放的，打包后就不能了，mid文件有打包进去jar的

求大神解答，应该是用相对途径吧，但就是不懂怎样改

改成这个试试。

String musicPath = "001/flourish.mid";
            InputStream input = this.getClass().getResourceAsStream(musicPath);
            buf = new BufferedInputStream(input);
