我想流mp3文件和访问他们使用Spring，但我不知道如何：（已经搜索过互联网，但还没有找到任何东西。我已经尝试过使用流，它的工作有点，但每首歌都从一开始，其他人也开始在歌曲的开始。我的代码：后端：

new Thread(() -> {
            stream = new ByteArrayOutputStream();
            while(true){
                try {
                    currentSong = files[rd.nextInt(files.length-1)];
                    InputStream is = new FileInputStream(new File(currentSong));
                    int read = 0;
                    byte[] bytes = new byte[1024];
                    while((read = is.read(bytes)) !=-1){
                            stream.write(bytes, 0, read);
                    }
                    stream.flush();
                    is.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();;

前端：

public class DnBController {
    @GetMapping("/dnb")
    public String play(HttpServletResponse httpServletResponse) throws IOException {
        OutputStream os = httpServletResponse.getOutputStream();
        httpServletResponse.setContentType("audio/mpeg");
        DnbradioApplication.stream.writeTo(httpServletResponse.getOutputStream());
        return "site.html";
    }
