儘管我從@ Andrew的代碼中大量提取，但我確實必須在這裏和那裏做一些調整。以下是我的解決方案的演示，除了一個示例.wav文件外，完整的。
// Developed in Eclipse, YMMV regarding resource location.
import java.net.URL;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
class ClipPlayer {
public static void main(String[] args) {
// First, instantiate ourselves so we can call demoSam which
// needs to be able to do a wait().
ClipPlayer cp = new ClipPlayer();
// Now run the actual demo
cp.demoSam();
}
private void demoSam() {
/**
* Construct a Sam, capable of playing the "Chook.wav", a 0.1 sec sound.
* NOTE: it's very tricky debugging an incorrectly-located
* resource file, and I'm unable to give a general rule
* here. But in this example, Chook.wav is expected to be in the same
* directory as the .class file, and there is no surrounding
* package (i.e. we're taking the default package name). If you
* are using a package, you may have to write "myPackage/Chook.wav"
* instead.
*/
Sam sam;
try {
sam = new Sam("Chook.wav"); // or whatever, but it has to be .wav
}
catch (Exception e) {
say("Exception thrown by Sam: " + e.getMessage());
System.exit(1); // scoot
return; // get rid of warning about sam possib not init'd
}
int countDown = 20;
do {
say("Doing something requiring accompanying sound effect...");
try {
sam.playIt();
}
catch (Exception e) {
say("Caught exception from playIt: " + e.getMessage());
System.exit(1);
}
// Now wait a human-scale duration, like 1/8 second. In
// practice we may be processing, since the sound is playing
// asynchronously.
synchronized (this) {
try {
wait(125); // wait 1/8 sec
}
catch (Exception e2) {
say("huh?");
}
}
} while (--countDown > 0);
}
/**
* 'Sam' is a class that implements one method, playIt(), that simply
* plays the .wav file clip it was instantiated with. Just using an
* inner class here for simplicity of demo.
*/
final class Sam {
AudioInputStream ais;
Clip clip;
/**
* Constructor: prepare clip to be played. Do as much here as
* possible, to minimize the overhead of playing the clip,
* since I want to call the play() method 5-10 times a second.
*/
Sam(String clipName) throws Exception {
// Resource is in same directory as this source code.
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL url = classLoader.getResource(clipName);
ais = AudioSystem.getAudioInputStream(url);
clip = AudioSystem.getClip();
clip.open(ais);
}
/**
* playIt(): Start the clip playing once, asynchronously, and exit.
*/
public void playIt() throws Exception {
clip.setFramePosition(0); // Must always rewind!
clip.loop(0);
clip.start();
}
}
private static void say(String s) {
System.out.println(s);
}
}
有趣的是：你的最後一行是'JOptionPane.showMessageDialog（null，「Close to end ..」）;'。如果不存在，聲音剪輯會在程序關閉後立即停止播放。我想知道@Chap是否知道這一點。 – toto2
對不起，格式不好，不知道如何實現報價塊。或者就此而言，新線路grrr。 Main.class.getResourceAsStream（）方法似乎需要導入com.sun.tools.apt.Main; 你從哪裏得到這個想法？我已經做了大量的聲音例子，從來沒有聽說過你不應該使用的那個類。 是的 - 這是由NetBeans或Eclipse的「清理導入」所提出的。 – Chap
@toto：不，但我很快就明白了:-) @andrew：感謝您的代碼。我想我可以將它與其他建議一起用於定位「本地」音頻文件資源。 – Chap
