Hello,<div><br></div><div>I&#39;d like to change Hibernate logging level to WARN.</div><div><br></div><div>As explained on <a href="http://docs.jboss.org/hibernate/core/3.5/reference/en/html/session-configuration.html#configuration-logging">this page</a>, you have to change the Hibernate Log Category &quot;org.hibernate&quot; to &quot;WARN&quot;. It works perfectly with log4j when I add &quot;log4j.logger.org.hibernate=WARN&quot; to log4j.properties file.</div>

<div>But when I change slf4j dependency to use logback instead of log4j and when I use the following logback.xml file, it doesn&#39;t work, I have Hibernate debug logs. Could you help me, please ?</div><div><br></div><div>

<div>&lt;configuration&gt;</div><div>    &lt;appender name=&quot;STDOUT&quot; class=&quot;ch.qos.logback.core.ConsoleAppender&quot;&gt;</div><div>        &lt;layout class=&quot;ch.qos.logback.classic.PatternLayout&quot;&gt;</div>

<div>            &lt;Pattern&gt;%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n&lt;/Pattern&gt;</div><div>        &lt;/layout&gt;</div><div>    &lt;/appender&gt;</div><div><br></div><div>    &lt;logger name=&quot;org.hibernate&quot;&gt;</div>

<div>        &lt;level value=&quot;WARN&quot;/&gt;</div><div>    &lt;/logger&gt;</div><div><br></div><div>    &lt;root level=&quot;DEBUG&quot;&gt;</div><div>        &lt;appender-ref ref=&quot;STDOUT&quot;/&gt;</div><div>
    &lt;/root&gt;</div>
<div>&lt;/configuration&gt;</div></div><div><br></div><div>Thanks.</div><div>Olivier</div>
