在沒有內存泄漏的Java播放音頻

我有一個當前的系統在我的遊戲中有一個AudioPlayer類，它擁有AudioChannels。我不斷收到堆轉儲（這是我看着與MAT）和朝導演：在沒有內存泄漏的Java播放音頻

com.sun.media.sound.DirectAudioDevice$DirectClip.open(Unknown Source)

在MAT泄漏看起來是這樣的：

我不知道該怎麼正在發生，因爲我盡我所能卸下Clip和AIS。

這是我用來播放音頻代碼：

try { 
    AudioInputStream ais = AudioSystem.getAudioInputStream(FileReader.getFile(s)); 
    clip = AudioSystem.getClip(); 
    clip.open(ais); 
    loaded = true; 

    FloatControl g = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN); 
    g.setValue((float)(g.getMinimum() + ((double)(g.getMaximum() - g.getMinimum()) * volume))); 

    if (loops) { 
     clip.loop(Clip.LOOP_CONTINUOUSLY); 
    } else { 
     clip.start(); 
    } 

    ais.close(); 
    clip.drain(); 
} catch (Exception e) { 
    e.printStackTrace(); 
}

您不關閉您的音頻剪輯。只要你是自由的，並且能夠，你應該儘量關閉它們：

if (clip.isOpen()) { 
    clip.close(); 
}

顯然，這可能需要您做更多的工作來跟蹤剪輯（S）的生命週期，所以你可以確信，他們可以以對您的應用程序有意義的方式發佈。

這是否解決您的問題，@Tyler賴特？ –
