//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
