音频文件在Eclipse IDE中播放；但不是JAR文件

音频文件在Eclipse IDE中播放；但不是JAR文件

Adding

clip.drain()

after

clip.start()

seems to have worked okay for me (IDE and command line
both with and without

&

)

import java.io.IOException;import java.net.URL;import javax.sound.sampled.AudioFormat;import javax.sound.sampled.AudioInputStream;import javax.sound.sampled.AudioSystem;import javax.sound.sampled.Clip;import javax.sound.sampled.DataLine;import javax.sound.sampled.LineUnavailableException;import javax.sound.sampled.UnsupportedAudioFileException;public class Sandbox {    public static void main(String[] args)  {        try { URL url = Sandbox.class.getResource("/sound-effects/Loud-alarm-clock-sound.wav"); AudioInputStream ais = AudioSystem.getAudioInputStream(url); AudioFormat af = ais.getFormat(); DataLine.Info info = new DataLine.Info(Clip.class, af); Clip clip = (Clip) AudioSystem.getLine(info); clip.open(ais); clip.start(); System.out.println("Drain..."); clip.drain(); System.out.println("...Drained");        } catch (UnsupportedAudioFileException | IOException | LineUnavailableException exp) { exp.printStackTrace();        }    }}

Now, having said that, I have found

drain

a little unreliable in the past,
especially when there are multiple sounds playing in which case I tend to use
a

LineListener

For example…

import java.io.IOException;import java.net.URL;import java.util.logging.Level;import java.util.logging.Logger;import javax.sound.sampled.AudioFormat;import javax.sound.sampled.AudioInputStream;import javax.sound.sampled.AudioSystem;import javax.sound.sampled.Clip;import javax.sound.sampled.DataLine;import javax.sound.sampled.LineEvent;import javax.sound.sampled.LineListener;import javax.sound.sampled.LineUnavailableException;import javax.sound.sampled.UnsupportedAudioFileException;public class Sandbox {    protected static final Object LOCK = new Object();    public static void main(String[] args) {        try { URL url = Sandbox.class.getResource("/sound-effects/Loud-alarm-clock-sound.wav"); AudioInputStream ais = AudioSystem.getAudioInputStream(url); AudioFormat af = ais.getFormat(); DataLine.Info info = new DataLine.Info(Clip.class, af); Clip clip = (Clip) AudioSystem.getLine(info); clip.open(ais); clip.addLineListener(new LineListener() {     @Override     public void update(LineEvent event) {         System.out.println(event.getType());         if (event.getType() == LineEvent.Type.STOP) {  synchronized (LOCK) {      LOCK.notify();  }         }     } }); clip.start(); synchronized (LOCK) {     LOCK.wait(); }        } catch (UnsupportedAudioFileException | IOException | LineUnavailableException | InterruptedException exp) { exp.printStackTrace();        }    }}
