//下载一个.mid文件命名为1，放在上述代码的包下

我想把我的java小程序中嵌入一个背景音乐，写出添加背景音乐代码。

放音乐的api网上查有很多，比如javax.sound.midi.*;

支持midi,mid背景音乐的播放

public class Music implements MetaEventListener, Runnable{

private Sequence sequence = null;

private Sequencer sequencer;

private boolean isPlaying = false;

private volatile Thread thread;

public Music(){

}

public Music(String midifile){

try {

loadMidi(midifile);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (InvalidMidiDataException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

//导入midi文件到内存中传给Sequence对象，相当与编码器

public void loadMidi(String filename) throws IOException, InvalidMidiDataException{

sequence = MidiSystem.getSequence(this.getClass().getResourceAsStream(filename));

}

//播放方法

public void play(){

if(isPlaying){

return;

}

try {

sequencer = MidiSystem.getSequencer();

sequencer.open();

//用Sequencer对象把声音文件序列解码出来播放

sequencer.setSequence(sequence);

sequencer.addMetaEventListener(this);

//设置循环次数，-1表示一直循环

sequencer.setLoopCount(-1);

sequencer.setLoopStartPoint(0);

sequencer.setLoopEndPoint(sequencer.getTickLength());

} catch (MidiUnavailableException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (InvalidMidiDataException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

if(thread == null){

thread = new Thread(this);

thread.start();

}

}

public void stop(){

if(isPlaying){

sequencer.stop();

isPlaying = false;

}

if(thread != null){

thread = null;

}

}

public void meta(MetaMessage meta) {

if(meta.getType() == 47){

System.out.println("Sequencer is done playing");

}

// TODO Auto-generated method stub

}

public void run() {

// TODO Auto-generated method stub

Thread current = Thread.currentThread();

while(current == thread !isPlaying){

sequencer.start();

isPlaying = true;

try {

thread.sleep(1001);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

//用起来也很方便

public static void main(String[] args){

Music music = new Music("a.mid");

music.play();

}

}

如果这样写路径类要和音频文件放在一个目录下，如果你不想这样，有两种方法，一种是修改路径字符串，另一种是把Class.getResourceAsStream方法改成new FileInputStream 这两个方法加载资源的初始路径不同，前者找class文件所在目录，后者找project目录

求在java中添加背景音乐的代码

不知道你是在java里哪添加？Swing界面中吗？

下面这个是我之前做Swing界面程序时添加音乐的代码，希望对你有帮助

AudioClip[] musics;//定义音乐集合

musics = new AudioClip[2];//初始化

URL url1 = this.getClass().getResource("/ReadyGo.WAV"); //定义音乐文件地址

URL url2 = this.getClass().getResource("/back1.mid"); //定义音乐文件地址

musics[0] = JApplet.newAudioClip(url1);

musics[1] = JApplet.newAudioClip(url2);

musics[0].play();//音乐开始执行

musics[1].stop();//停止播放

跪求java 音乐播放的代码啊，完美运行的就行
