我想使用java代码播放.wav文件，该代码位于jar文件中作为资源。我的代码看起来像这样 -
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();
}
WindowsNavigationStart.wav文件存在于我的一个jar文件中。但得到以下例外 -
java.lang.IllegalArgumentException: URI is not hierarchical

请给我一个解决方案。谢谢你们。
更改：
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);
至：
System.out.println("defaultSound " + defaultSound); // check the URL!
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(defaultSound);
你有没有尝试过：
InputStream is= getClass().getResourceAsStream("/images/ads/WindowsNavigationStart.wav");
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(is);
基本上我认为你不能在jar文件中用URI创建一个文件。但是您可以直接传递输入流。
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);
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();
请参阅我之前在making a single-jar java application的回答。标题是误导性的，但海报试图做一些几乎与你相同的事情。一些最佳细节位于聊天记录的链接中。
try {
AudioPlayer.player.start(new AudioStream(getClass().getResourceAsStream("/sound/SystemNotification.wav")));
} catch (Exception e) {
e.printStackTrace();
}
这对我来说很好：
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();
}
}
以下允许我在Eclipse项目和导出的jar文件中播放声音： - 注意使用BufferedInputStream - 注意，使用inputStream而不是file。
在我的main（）中：
playAlarmSound();
在我班上：
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();
}
}
像Kal写道：
- InputStream = getClass（）。getResourceAsStream（“......”）;
- AudioInputStream ais = AudioSystem.getAudioInputStream（also）;
我这样做了，它起初没有用，但是“java.io.IOException”的问题是我使用了File.separator，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;
}
