Log4j和Jboss。如何獲得我的log.Debug（「Debug」）消息以顯示？

我試圖啓動我的jBoss服務器（v4.2）來運行並顯示我所有的log.debug消息。我需要通過編輯jboss配置來實現這一點。不是以編程方式通過應用程序。Log4j和Jboss。如何獲得我的log.Debug（「Debug」）消息以顯示？

頁我測試

private static final Logger log = Logger.getLogger(ServerLogsController.class 
    .getName()); 

@GET 
    @Path("/testDebug") 
    public String testDebug(@Context final ServletContext context) 
    { 
    log.error("This is an error which always shows!"); 
    log.debug("This is a debug message"); 

    return "Test Debug Page"; 
    }

你的''conf /'文件夾中有'log4j.xml'或'jboss-log4j.xml'文件嗎？您通常編輯log4j xml文件以修改調試級別。 – cklab

@cklab這確實敲jboss到調試模式，但我仍然無法顯示我的log4j.debug消息。 – stackoverflow

你可以發佈你的'log4j.xml'文件嗎？ – cklab

有兩種方法我能想到的，以獲得調試消息顯示在這裏：

1）您可以在xml文件中爲ServerLogsContr添加一個新條目oller顯示DEBUG消息。

<category name="package.for.ServerLogsController"> 
    <priority value="DEBUG" /> 
    <appender-ref ref="CONSOLE"/> 
    <appender-ref ref="FILE"/> 
</category>

，你用正確的軟件包名稱替換package.for.ServerLogsController。請注意，您也可以將其設置爲package.for，並且該目錄下的所有文件都將記錄@DEBUG級別。此設置將覆蓋在第二項中提到根的行爲（即，如果根被設置爲DEBUG但package.for.ServerLogsController設置爲ERROR，你不會看到package.for.ServerLogsControllerDEBUG消息。

2）設置調試根包

<root> 
    <priority value="DEBUG"/> 
    <appender-ref ref="CONSOLE"/> 
    <appender-ref ref="FILE"/> 
</root>

這將使所有的包記錄在DEBUG水平，除非有包，專門重寫。

我很感激幫助。我剛剛嘗試過，儘管我現在正在接收服務器調試消息，但我仍然無法在log.debug（「這是一條調試消息」）中顯示消息 – stackoverflow

您選擇了哪個選項？你看到'這是一個總是顯示的錯誤！'？哪個包是'ServerLogsController'中的？ – cklab

我向控制器指定了正確的軟件包，但仍未顯示調試消息。消息「這是一個總是顯示的錯誤！」顯示，但這不是我想要得到的輸出。 – stackoverflow

Log4j和Jboss。如何獲得我的log.Debug（「Debug」）消息以顯示？
