我想在代码中提供的URL处获取声音文件并播放它(mp3格式为).我查看了一些与此问题相关的Stack Overflow问题,他们都说过mp3plugin.jar这样做了.

在Eclipse中,我在配置构建路径下将其添加为外部jar(因为它位于我的Downloads文件夹中,不确定它是否是最佳位置).我再次运行它,它仍然给我这个错误:

javax.sound.sampled.UnsupportedAudioFileException:无法从 Starter.main
上的javax.sound.sampled.AudioSystem.getAudioInputStream(未知来源)的输入流中获取音频输入流
(Starter.java:21)

这是代码:

public class Starter {

    public static void main(String[] args) {
        AudioInputStream din = null;
        try {
            URL url = new URL("http://c5.rbxcdn.com/2e6d33a5b3b1d8f250c395816ff9f145");
            HttpURLConnection httpcon = (HttpURLConnection) url.openConnection();
            InputStream bufferedIn = new BufferedInputStream(httpcon.getInputStream());
            AudioInputStream in = AudioSystem.getAudioInputStream(bufferedIn);
            AudioFormat baseFormat = in.getFormat();
            AudioFormat decodedFormat = new AudioFormat(
                    AudioFormat.Encoding.PCM_SIGNED,
                    baseFormat.getSampleRate(), 16, baseFormat.getChannels(),
                    baseFormat.getChannels() * 2, baseFormat.getSampleRate(),
                    false);
            din = AudioSystem.getAudioInputStream(decodedFormat, in);
            DataLine.Info info = new DataLine.Info(SourceDataLine.class, decodedFormat);
            SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info); …
