java基於BasicPlayer調用 播放音樂

無聊中想一想用java調用下聽音樂的api。晚上不少文章用的比較老大方法了，都是用原生的代碼寫，並且不支持mp3格式，BasicPlayer第三方包提供了很好的api調用，簡單的3行代碼就能夠調用mp3了。若是喜歡本身動手的，能夠去BasicPlayer官網下載源代碼，裏面包含所須要的jar包和測試類。

 

先介紹下BasicPlayer。官方是這樣介紹的：

BasicPlayer層是jlGui的簡單播放器API。這些類被設計用於須要簡單功能（播放，中止，暫停，恢復，尋找）播放音頻文件或流的任何應用程序。它是JavaSound API的高級API。

 

官網地址：http://www.javazoom.net/jlgui/api.html 

 

官方源代碼中包含包有：

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！這個版本若是出現了java.io.IOException: Resetting to invalid mark       這個錯誤，須要把版本更新到mp3spi1.9.5.jar就解決了）

8：tritonus_share.jar

vorbisspi1.0.2.jar

 

在測試前要確保網卡和音響或耳機正常，否則會提示一些莫名的錯誤哦。

 

下面貼出我測試成功的代碼。以下
