java播放音频文件

方法1：

package za;
import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;
import java.net.URL;

public class Music {
	public Music()
	{
		try
		{
	//		URL url=new URL("file:\\D:\\清明雨上.wav");		
			URL url=new URL("file:"+File.separator+"D:"+File.separator+"清明雨上.wav");
			AudioClip ac=Applet.newAudioClip(url);
			ac.play();        //ac.stop();
		}
		catch(Exception e)
		{
			System.out.println(e);
		}
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub		
		new Music();
	}
}

方法2：

使用AudioStream，需要导入

import sun.audio.AudioPlayer;
import sun.audio.AudioStream;

上面这两句都报“Access restriction: The type AudioPlayer is not accessible due to restriction on required library C:\JDK1.5\jre\lib\rt.jar”的错误，解决办法：：在preference->java->complier->errors/warning->deprecated and restricted API把 Forbidden reference 的Error改成warning 即可，参考http://www.cnblogs.com/Cratical/archive/2011/05/11/2043756.html 原因。

package za;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
import java.io.*;
public class Sound 
{
	public static void main(String args[])
	{
		try 
		{
			FileInputStream file=new  FileInputStream("D:\\清明雨上.wav");
			AudioStream as=new AudioStream(file);
			AudioPlayer.player.start(as);
		}catch (Exception e) {}
	}
}

方法3:

使用AudioInputStream

程序运行正常，但没声音的解决方法：

没声音？

JDK 5 发行版中有个讨厌的小错误：在有些平台上，对于一些短的音频片段，代码看上去运行正常，但就是 ... 没声音。显然媒体播放器在应该出现的位置之前触发了 STOP 事件。（见 参考资料 一节中错误页的链接。）

这个错误 “无法修复”，但解决方法相当简单：注册一个 LineListener 来监听 STOP 事件，当触发时，调用片段对象的 notifyAll()。然后在 “调用者” 代码中，通过调用 wait() 等待片段完成（还调用 notifyAll()）。在没出现错误的平台上，这些错误是多余的，在 Windows® 及有些 Linux® 版本上，会让程序员 “开心” 或 “愤怒”。

package za;

import java.io.File;
import javax.sound.sampled.*;

public class MusicTest
{
	public static void main(String args[])
	{
		try{
			new MusicTest().playClip("D:"+File.separator+"清明雨上.wav");
		}catch(Exception e)
		{
			e.printStackTrace();
		}
	}
	public void playClip(String audioFile)
	{
	    try
	    {
	    /*    AudioInputStream inputStream =
	            AudioSystem.getAudioInputStream(
	                this.getClass().getResourceAsStream(audioFile));*/
	        AudioInputStream inputStream=AudioSystem.getAudioInputStream(new File(audioFile));
	        DataLine.Info info = 
	            new DataLine.Info( Clip.class, inputStream.getFormat());
	        final Clip clip = (Clip) AudioSystem.getLine(info);
	        clip.addLineListener(new LineListener() {
	                public void update(LineEvent e) {
	                    if (e.getType() == LineEvent.Type.STOP) {
	                        synchronized(clip) {
	                            clip.notify();
	                        }
	                    }
	                }
	            });
	        clip.open(inputStream);
	        clip.setFramePosition(0);
	        clip.start();
	        synchronized (clip) {
	            clip.wait();
	        }
	        clip.drain();
	        clip.close();
	    }
	    catch (Exception ex)
	    {
	        ex.printStackTrace();
	    }
	}
