import java.io.FileNotFoundException;
import java.io.IOException;
import java.net.URL;
import sun.audio.AudioData;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
import sun.audio.ContinuousAudioDataStream;

public class MusicPlay {
	private AudioStream as; // 单次播放声音用
	ContinuousAudioDataStream cas;// 循环播放声音

	// 构造函数
	public MusicPlay(URL url) {
		try {
			// 打开一个声音文件流作为输入
			as = new AudioStream(url.openStream());
		} catch(FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch(IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	// 一次播放 开始
	public void start() {
		if(as == null) {
			System.out.println("AudioStream object is not created!");
			return;
		} else {
			AudioPlayer.player.start(as);
		}
	}

	// 一次播放 停止
	public void stop() {
		if(as == null) {
			System.out.println("AudioStream object is not created!");
			return;
		} else {
			AudioPlayer.player.stop(as);
		}
	}

	// 循环播放 开始
	public void continuousStart() {
		// Create AudioData source.
		AudioData data = null;
		try {
			data = as.getData();
		} catch(IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		// Create ContinuousAudioDataStream.
		cas = new ContinuousAudioDataStream(data);

		// Play audio.
		AudioPlayer.player.start(cas);
	}

	// 循环播放 停止
	public void continuousStop() {
		if(cas != null) {
			AudioPlayer.player.stop(cas);
		}
	}

}

 

使用：

MusicPlay myMusicPlay = new MusicPlay(MusicPlay.class.getResource("/music/dog.wav"));
myMusicPlay.start();//播放一次
myMusicPlay.stop();//停止
myMusicPlay.continuousStart();//循环播放
myMusicPlay.continuousStop();//停止

 注意这里只是示例，stop与start不能连用，另这程序试验过，无法播放mp3音频文件
