使用java将jar中的.wav文件作为资源播放

Question

我想使用 jar 文件中的 java 代码作为资源来播放 .wav 文件。我的代码是这样的 -

try {
     URL defaultSound = getClass().getResource("/images/ads/WindowsNavigationStart.wav");
     // getClass().getSy.getResource("/images/ads/WindowsNavigationStart.wav");
     File soundFile = new File(defaultSound.toURI());
     AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);
     Clip clip = AudioSystem.getClip();
     clip.open(audioInputStream);
     clip.start( );
} catch (Exception ex) {
     ex.printStackTrace();
}

文件 WindowsNavigationStart.wav 存在于我的一个 jar 文件中。但得到以下异常 -

请给我一个解决方案。谢谢大家。

Answer 1

请参考我之前在making a single-jar java application 的回答。标题具有误导性，但张贴者试图做的事情几乎与您相同。聊天记录的链接中提供了一些最好的详细信息。

Answer 2

你试过了吗：

InputStream is= getClass().getResourceAsStream("/images/ads/WindowsNavigationStart.wav");
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(is);

基本上我认为您不能从 jar 文件中的 URI 创建文件。但是您可以直接传递输入流。

Answer 3

使用Class.getResourceAsStream()

获得 inputStream 的句柄后，获取 audioInputStream 并完成剩下的工作。

InputStream is = getClass().getResourceAsStream("......");
AudioInputStream ais = AudioSystem.getAudioInputStream(is);
Clip clip = AudioSystem.getClip();
clip.open(ais);

Answer 4

变化：

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);

收件人：

System.out.println("defaultSound " + defaultSound);  // check the URL!
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(defaultSound);

Answer 5

完美解决方案......

URL url = this.getClass().getResource("sounds/beep.au");

String urls=url.toString(); 
urls=urls.replaceFirst("file:/", "file:///");

AudioClip ac=Applet.newAudioClip(new URL(urls));

ac.play();

Answer 6

     try {
        AudioPlayer.player.start(new AudioStream(getClass().getResourceAsStream("/sound/SystemNotification.wav")));
    } catch (Exception e) {
        e.printStackTrace();
    }

Answer 7

这对我来说很好用：

public void playSound() {
        InputStream in;
        try {
            in = new BufferedInputStream(new FileInputStream(new File(
                    getClass().getClassLoader()
                            .getResource("com/kaito/resources/sound.wav").getPath())));
            AudioStream audioStream = new AudioStream(in);
            AudioPlayer.player.start(audioStream);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Answer 8

以下允许我在 Eclipse 项目中播放声音和导出的 jar 文件：
- 注意使用了 BufferedInputStream
- 注意，使用的是 inputStream 而不是文件。

在我的 main() 中：

playAlarmSound();

在我的课堂上：

public static void playAlarmSound() {
ClassLoader classLoader = App.class.getClassLoader();
InputStream inputStream = classLoader.getResourceAsStream("alarmsound.wav");
try {
  Clip clip = AudioSystem.getClip();
  AudioInputStream ais = AudioSystem.getAudioInputStream(new BufferedInputStream(inputStream));
  clip.open(ais);
  clip.start();
} catch (IOException | LineUnavailableException | UnsupportedAudioFileException e) {
  System.err.println("ERROR: Playing sound has failed");
  e.printStackTrace();
}
}

Answer 9

就像 Kal 写的：

1. InputStream is = getClass().getResourceAsStream("......");
2. AudioInputStream ais = AudioSystem.getAudioInputStream(is);...

我就是这样做的，一开始它没有用，但“java.io.IOException”的问题是我使用了 File.separator 并且由于某种原因 win 8.1 无法处理“\\”...

public AudioInputStream getSound(String fileName){
    InputStream inputSound;
    AudioInputStream audioInStr;
    String fs = File.separator;

    try {
       absolutePath = fs +packageName+ fs +folderName+ fs +fileName;
       inputSound = getClass().getResourceAsStream(absolutePath);

       //if null pointer exception try unix, for some reason \\ doesn't work on win 8.1
       if(inputSound == null) {
           absolutePath = "/" + packageName + "/" + folderName + "/" + fileName;
           inputSound = getClass().getResourceAsStream(absolutePath);
       }

       audioInStr = AudioSystem.getAudioInputStream(new BufferedInputStream(inputSound));
       return audioInStr;
    }
