java播放mp3格式音频文件

1. 下载第三方jar包，网址：http://www.javazoom.net/javalayer/javalayer.html
   
2. 下载完成之后解压提取jl1.0.0.1.jar
   
3. 将jl1.0.0.1.jar拷贝到项目中，并添加到Library
   
   4.源代码

//Tip: 由于工程名和包名不一样，最好手打不要盲目复制

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();
    }
}

5.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.*;
/***
 * 音乐播放器类
 * @author lt
 *  time 2016-7-5
 */
 //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();
    }
}
