java播放mp3格式音频文件
下载第三方jar包，网址：http://www.javazoom.net/javalayer/javalayer.html
将jl1.0.0.1.jar拷贝到项目中，并添加到Library
源代码
package com.lt.music;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.*;

public class AudioPlayer{
Player player;
File music;
//构造方法 参数是一个.mp3音频文件
public AudioPlayer(File file) {
this.music = file;
}
//播放方法
public void play() throws FileNotFoundException, JavaLayerException {
BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(music));
player = new Player(buffer);
player.play();
}
}
如果想把音乐播放作为其他程序的背景音乐，则可以让其继承Thread，代码如下：
package com.lt.music;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.*;
/***

//继承自线程类Thread
public class AudioPlayer extends Thread{
Player player;
File music;
//构造方法
public AudioPlayer(File file) {
this.music = file;
}
//重写run方法
@Override
public void run() {
super.run();
try {
play();
} catch (FileNotFoundException | JavaLayerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//播放方法
public void play() throws FileNotFoundException, JavaLayerException {
BufferedInputStream buffer =
new BufferedInputStream(new FileInputStream(music));
player = new Player(buffer);
player.play();
}
}
