是否有可能在jboss-7日誌記錄中擁有多個具有相同類別的處理程序？

Question

我定義了兩個處理程序在standalone.xml文件具有相同名稱的類別，如下面

<logger category="ab.cd" use-parent-handlers="false"> 
      <level name="DEBUG" /> 
      <handlers> 
       <handler name="abDebug" /> 
      </handlers> 
     </logger> 
<logger category="ab.cd" use-parent-handlers="true"> 
       <level name="WARN" /> 
       <handlers> 
        <handler name="abWarning" /> 
       </handlers> 
      </logger> 

但我得到異常，當我嘗試運行JBoss的7

所以，我想要知道是否有可能有兩個相同類別的記錄器？如果不是，那麼在這種情況下如何將數據發送給兩個不同的處理程序？

Answer 1

您不能有兩個具有相同類別定義的記錄器。記錄器如何知道應該使用哪個級別？您最好使用一個沒有設置級別的記錄器，並使用處理程序設置要記錄的級別。

類似以下內容：

<file-handler name="abDebug" auto-flush="true"> 
    <level name="DEBUG"/> 
    <file relative-to="jboss.server.log.dir" path="abDebug.log"/> 
    <append value="true"/> 
</file-handler> 
<file-handler name="abWarning" auto-flush="true"> 
    <level name="WARN"/> 
    <file relative-to="jboss.server.log.dir" path="abWarning.log"/> 
    <append value="true"/> 
</file-handler> 

<logger category="ab.cd"> 
    <handlers> 
     <handler name="abDebug" /> 
     <handler name="abWarning" /> 
    </handlers> 
</logger>
