Spring AMQP logs repeating despite disabling in log4j.xml

Question

I am receiving the following logs repeatedly while using Spring AMQP:

01:21:54.323 [SimpleAsyncTaskExecutor-1] DEBUG o.s.a.r.l.BlockingQueueConsumer - Retrieving delivery for Consumer: tag=[amq.ctag-XAaHUPISVTmjpL-am3y15g], channel=Cached Rabbit Channel: AMQChannel(....), acknowledgeMode=AUTO local queue size=0 01:21:55.325 [SimpleAsyncTaskExecutor-1] DEBUG o.s.a.r.l.BlockingQueueConsumer - Retrieving delivery for Consumer: tag=[amq.ctag-XAaHUPISVTmjpL-am3y15g], channel=Cached Rabbit Channel: AMQChannel(....), acknowledgeMode=AUTO local queue size=0 01:21:56.327

My log.xml file looks like this

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<!-- Appenders -->
<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%-5p: %c - %m%n" />
    </layout>
</appender>
....
<logger name="org.springframework.amqp.rabbit">
    <level value="off" />
</logger>

<logger name="org.springframework.amqp">
    <level value="off" />
</logger>
<!-- Root Logger -->
<root>
    <priority value="off" />
    <appender-ref ref="console" />
</root>

</log4j:configuration>

Upon closer inspection I found that the BlockingQueueConsumer class in org.springframework.amqp.rabbit emits the above logs and the exact line is

if (logger.isDebugEnabled()) {
            logger.debug("Retrieving delivery for " + this);
        }

My question is how is this possible given the above log4j.xml entries. Am I missing something. I am using the following loggers slf4j-api-1.6.6.jar,slf4j-log4j12-1.6.6.jar,log4j-1.2.15.jar

EDIT

With reference to the comments by zapl I started this project with STS and used a new Spring MVC Project the log files weren't manually configured. Is the project reading the log file from some other xml?

Are you sure this config file is actually in use, e.g. when you change the pattern is that change picked up? (shouldn't it print DEBUG: with : ?) — zapl

Thanks for pointing that out zapl. I found the issue. In the web.xml file you should mention this

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/resource/log4j.properties</param-value>
</context-param>

 <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

Refer to this answer: How to configure the log4j output file path in web.xml and log4j.properties?
