Hi <br><br>I&#39;ve write a config like this<br><br>&lt;configuration&gt;<br><br>    &lt;appender name=&quot;Chii2FILE&quot; class=&quot;ch.qos.logback.core.FileAppender&quot;&gt;<br>        &lt;file&gt;log/chii2.log&lt;/file&gt;<br>
<br>        &lt;encoder&gt;<br>            &lt;pattern&gt;%date{yyyy-MM-dd HH:mm:ss} [%level] %logger{50} [%file:%line] %msg%n&lt;/pattern&gt;<br>        &lt;/encoder&gt;<br>    &lt;/appender&gt;<br><br>    &lt;appender name=&quot;FILE&quot; class=&quot;ch.qos.logback.core.FileAppender&quot;&gt;<br>
        &lt;file&gt;log/platform.log&lt;/file&gt;<br><br>        &lt;encoder&gt;<br>            &lt;pattern&gt;%date{yyyy-MM-dd HH:mm:ss} [%level] %logger{50} [%file:%line] %msg%n&lt;/pattern&gt;<br>        &lt;/encoder&gt;<br>
    &lt;/appender&gt;<br><br>    &lt;logger name=&quot;org.chii2&quot; level=&quot;debug&quot;&gt;<br>        &lt;appender-ref ref=&quot;Chii2FILE&quot;/&gt;<br>    &lt;/logger&gt;<br><br>    &lt;root level=&quot;warn&quot;&gt;<br>
      &lt;appender-ref ref=&quot;FILE&quot; /&gt;<br>    &lt;/root&gt;<br><br>&lt;/configuration&gt;<br><br>The problem is, all the log in chii2.log will repeat in platform.log.<br>I want separate my project&#39;s log from others.<br>
How can I do that?<br><br>Regards<br>LongkerDandy<br>
