無法從輸入文件獲取音頻輸入流

Question

我想播放文件java。我正在使用代碼，但顯示異常無法從輸入文件獲取音頻輸入流。 我的源代碼是：

try { 
     System.out.println("Start"); 
     File f = new File("E:\\malayalam good song\\01_ISHTAMANU.MP3"); 

     AudioInputStream audio = AudioSystem.getAudioInputStream(f); 
     System.out.println("Start"); 
     AudioFormat format = audio.getFormat(); 
     DataLine.Info info = new DataLine.Info(SourceDataLine.class, format); 
     SourceDataLine auline = (SourceDataLine) AudioSystem.getLine(info); 
     auline.open(format); 
     auline.start(); 
     int nBytesRead = 0; 
     byte[] abData = new byte[524288]; 
     while (nBytesRead != -1) { 
      nBytesRead = audio.read(abData, 0, abData.length); 
      if (nBytesRead >= 0) { 
       auline.write(abData, 0, nBytesRead); 
      } 
     } 
    } catch (Exception E) { 
     System.out.println("Exception"+E.getMessage()); 
    } 

Answer 1

添加mp3plugin.jar classpath中。

Answer 2

如果您在java 7，有新的（JavaFX）班有更易於使用：

import javafx.scene.media.Media; 
import javafx.scene.media.MediaPlayer; 
... 
... 

try { 
     File f = new File("E:\\malayalam good song\\01_ISHTAMANU.MP3"); 
     Media hit = new Media(f.toURI().toString()); 
     MediaPlayer mediaPlayer = new MediaPlayer(hit); 
     mediaPlayer.play(); 
    } catch(Exception ex) { 
     ex.printStackTrace(); 
     System.out.println("Exception: " + ex.getMessage()); 
    } 

如果你不在Java 7，你可以從搶JavaFX罐here。
