java基于BasicPlayer调用 播放音乐

无聊中想想用java调用下听音乐的api。晚上很多文章用的比较老大方法了，都是用原生的代码写，而且不支持mp3格式，BasicPlayer第三方包提供了很好的api调用，简单的3行代码就可以调用mp3了。如果喜欢自己动手的，可以去BasicPlayer官网下载源代码，里面包含所需要的jar包和测试类。

先介紹下BasicPlayer。官方是这样介绍的：

BasicPlayer层是jlGui的简单播放器API。这些类被设计用于需要简单功能（播放，停止，暂停，恢复，寻找）播放音频文件或流的任何应用程序。它是JavaSound API的高级API。

官网地址：http://www.javazoom.net/jlgui/api.html 

官方源代码中包含包有：

1：basicplayer3.0.jar

2：commons-logging-api.jar

3：jl1.0.jar

4：jogg-0.0.7.jar

5：jorbis-0.0.15.jar

6：jspeex0.9.7.jar

7：mp3spi1.9.4.jar （注意！这个版本如果出现了java.io.IOException: Resetting to invalid mark       这个错误，需要把版本更新到mp3spi1.9.5.jar就解决了）

8：tritonus_share.jar

vorbisspi1.0.2.jar

在测试前要确保网卡和音响或耳机正常，不然会提示一些莫名的错误哦。

下面贴出我测试成功的代码。如下

package fff;
