wav 声音没有在 jar 中播放

772

我正在尝试在应用程序中播放声音。从 IntelliJ IDEA 启动时，一切正常，但是当我收集 jar 工件并运行它时，里面没有声音。可能是什么问题呢？编码：

// воспроизведение звука
private void SoundPlay(int second) throws URISyntaxException {
    soundCountdown = null;
    soundEnd = null;

    try {
        InputStream bufferedIn1 = new BufferedInputStream(Main.class.getResourceAsStream("number.wav"));
        InputStream bufferedIn2 = new BufferedInputStream(Main.class.getResourceAsStream("null.wav"));

        AudioInputStream aff1 = AudioSystem.getAudioInputStream(bufferedIn1);
        AudioFormat af1 = aff1.getFormat();
        DataLine.Info info1 = new DataLine.Info(Clip.class, af1);

        AudioInputStream aff2 = AudioSystem.getAudioInputStream(bufferedIn2);
        AudioFormat af2 = aff2.getFormat();
        DataLine.Info info2 = new DataLine.Info(Clip.class, af2);

        // звук 0 секунд
        if (second == 0) {
            if (AudioSystem.isLineSupported(info2)) {
                soundEnd = (Clip) AudioSystem.getLine(info2);
                AudioInputStream ais2 = AudioSystem.getAudioInputStream(bufferedIn2);
                soundEnd.open(ais2);
                soundEnd.start();
            } else { System.exit(0); }
        }

        // звук 3, 2, 1 секунд
        if (second <= 3 && second != 0) {
            if (AudioSystem.isLineSupported(info1)) {
                soundCountdown = (Clip) AudioSystem.getLine(info1);
                AudioInputStream ais1 = AudioSystem.getAudioInputStream(bufferedIn1);
                soundCountdown.open(ais1);
                soundCountdown.start();
            } else { System.exit(0); }

        }
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("Ошибка воспроизведения звука!");
    }
}

我重写了您的代码以使其工作：

import javax.sound.sampled.LineEvent.Type; // Классов Type в jdk много, поэтому указал верный


public class Main {
    public static void main(String[] args) throws URISyntaxException {
        new Main().soundPlay(0);
    }

    static class AudioListener implements LineListener { // Слушатель окончания звука,
                                                         // без него прога завершится сразу
                                                         // после начала проигрывания. (clip.start();)
                                                         // (не завершится если дальше будет код).
        private boolean done = false;
        @Override public synchronized void update(LineEvent event) {
          Type eventType = event.getType();
          if (eventType == Type.STOP || eventType == Type.CLOSE) {
            done = true;
            notifyAll();
          }
        }
        public synchronized void waitUntilDone() throws InterruptedException {
          while (!done) { wait();}
        }
      }

    private void soundPlay(int second) throws URISyntaxException {
        try {
            // Чтение при помощи потоков, прямо из jar 
            // (+ слеш т.к без него скомпилированная прога не работает.)
            InputStream bufferedIn1 = new BufferedInputStream(Main.class.getResourceAsStream("/number.wav"));
            InputStream bufferedIn2 = new BufferedInputStream(Main.class.getResourceAsStream("/null.wav"));

            AudioListener listener = new AudioListener();

            if (second == 0) {
                AudioInputStream ais = AudioSystem.getAudioInputStream(bufferedIn1);
                if( !AudioSystem.isLineSupported(new DataLine.Info(Clip.class, ais.getFormat())) ) System.exit(-1); // Всё в одной строке

                Clip clip = AudioSystem.getClip();
                clip.addLineListener(listener); // Добавление слушателя.
                clip.open(ais);
                clip.start();
                listener.waitUntilDone(); // Пауза до окончания клипа (звука).
            } else if (second <= 3) {
                AudioInputStream ais = AudioSystem.getAudioInputStream(bufferedIn2);
                if( !AudioSystem.isLineSupported(new DataLine.Info(Clip.class, ais.getFormat())) ) System.exit(-1);

                Clip clip = AudioSystem.getClip();
                clip.addLineListener(listener);
                clip.open(ais);
                clip.start();
                listener.waitUntilDone();
            }
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("Ошибка воспроизведения звука! Надеюсь это не напечатается :)");
        }
    }
}

评论中有提示，AudioListener类是从这里老实说的：Trouble playing wav in Java。
