如何禁止htmlunit（Java庫）警告/錯誤消息？

我使用的HtmlUnit [http://htmlunit.sourceforge.net/]，它噴出了一堆警告/錯誤：如何禁止htmlunit（Java庫）警告/錯誤消息？

Mar 24, 2017 6:37:30 PM com.gargoylesoftware.htmlunit.IncorrectnessListenerImpl notify WARNING: Obsolete content type encountered: 'text/javascript'. Mar 24, 2017 6:37:31 PM com.gargoylesoftware.htmlunit.html.InputElementFactory createElementNS INFO: Bad input type: "datetime", creating a text input Mar 24, 2017 6:37:31 PM com.gargoylesoftware.htmlunit.IncorrectnessListenerImpl notify WARNING: Obsolete content type encountered: 'application/x-javascript'.

我已經看了其他資源，並試圖將其關閉：

Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF); 
    Logger.getLogger("org.apache.http").setLevel(Level.OFF);

和：

 final WebClient webClient = new WebClient(BrowserVersion.EDGE);

但不起作用。

還能做些什麼來抑制這些警告/錯誤信息？

確保調用之前的HtmlUnit要設置記錄器。如果沒有，請發佈您的完整代碼 –

謝謝，我把代碼和多一行（請參閱我的答案），錯誤/收入停止出現。 – ikevin8me

如果你不打算在「logging.properties」文件中設置的記錄器OFF那麼你之前需要pin the loggers with a hard reference您將級別設置爲OFF。

這是基於把你的代碼校正例如：

private static final Logger[] PINNED_LOGGERS; 
static { 
    System.setProperty("org.apache.commons.logging.simplelog.defaultlog", "fatal"); 
    PINNED_LOGGERS = new Logger[]{ 
     Logger.getLogger("com.gargoylesoftware.htmlunit"), 
     Logger.getLogger("org.apache.http") 
    }; 

    for (Logger l : PINNED_LOGGERS) { 
     l.setLevel(Level.OFF); 
    } 
}

謝謝！現在我明白你的意思是「固定」在記憶中。 :-) – ikevin8me

我把在應用程序和錯誤的開始，以下/警告停止：

System.getProperties().put("org.apache.commons.logging.simplelog.defaultlog", "fatal"); 
Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF); 
Logger.getLogger("org.apache.http").setLevel(Level.OFF);

你應該[將這些記錄器固定在內存中]（http://stackoverflow.com/questions/22689831/log-file-not-being-updated-after-few-seconds-while-using-logger-and-filehandler/22698423 ＃22698423），然後將它們設置爲「OFF」。否則，您可能會失去剛剛應用的設置。 – jmehrens

我不明白。我不需要保留這些日誌。 – ikevin8me

如果記錄器在被設置爲「OFF」之前未被某些代碼固定，則記錄器可能被垃圾收集。如果在htmlunit發佈之前發生這種情況，就好像你從未將它們設置爲「關閉」。 – jmehrens
