Quick Start:
新建一個(gè)java project，項(xiàng)目名為Oops_JMF
在項(xiàng)目里面添加一個(gè)lib目錄，并添加以下jar文件，全部可以在jmf-2_1_1e-windows-i586.exe里面找到
在src目錄下面添加以下文件：
SimpleAudioPlayer.java
import javax.media.*;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.net.MalformedURLException;
public class SimpleAudioPlayer
{
private Player audioPlayer = null;
public SimpleAudioPlayer(URL url) throws IOException, NoPlayerException,
CannotRealizeException
{
audioPlayer = Manager.createRealizedPlayer(url);
}
public SimpleAudioPlayer(File file) throws IOException, NoPlayerException,
CannotRealizeException
{
this(file.toURL());
}
public void play()
{
audioPlayer.start();
}
public void stop()
{
audioPlayer.stop();
audioPlayer.close();
}
}
TestCase.java
import java.io.File;
import java.io.IOException;
import javax.media.CannotRealizeException;
import javax.media.NoPlayerException;
public class TestCase
{
/**
* @param args
*/
public static void main(String[] args)
{
File audioFile = new File("demo.mp3");
try
{
SimpleAudioPlayer player = new SimpleAudioPlayer(audioFile);
System.out.println("music begin");
player.play();
System.out.println("music end");
} catch (NoPlayerException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (CannotRealizeException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
在項(xiàng)目根目錄下面放置一個(gè)demo.mp3文件，最后整個(gè)項(xiàng)目變成：
右鍵點(diǎn)擊項(xiàng)目，run as java application
設(shè)置好運(yùn)行環(huán)境
成功！
發(fā)現(xiàn)很有趣。整個(gè)application運(yùn)行完了，但是音樂還在繼續(xù)。估計(jì)內(nèi)部開了線程。
