JBoss 7.3.0, Spring, slf4j implementation log4j logging not working

Question

Not sure what I am missing, trying to implement Log4J logging in my JBoss Spring application as defined here: Hibernate logging in Spring application on JBoss 7.1

But it doesn't seem to be picking up the configurations defined in my webapp/WEB-INF/classes/log4j.properties

pom.xml:

     <properties>
         <org.slf4j-version>1.7.5</org.slf4j-version>
    </properties>

            </exclusions>
         </dependency>

META-INF/jboss-deployment-structure.xml:

<jboss-deployment-structure>
    <deployment>

            <module name="org.slf4j.impl" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

WEB-INF/classes/log4j.properties:

log4j.rootLogger=INFO, A1, R

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.Target=System.out
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.logger.org.hibernate=DEBUG
log4j.logger.com.bagel=INFO

TestController.java:

package com.bagel.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Controller
public class TestController {

private final static Logger LOGGER = LoggerFactory.getLogger(TestController.class.getName());

  @RequestMapping("/test")
  public void test(){
    LOGGER.info("Test Logging");
  }

}

And I am definitely sure that my Controller method test is being invoked, however it does not log the required "Test Logging"

Hi James SLF4J is simply an interface. It requires an underlying implementation at run time e.g: java.util.logging, logback, log4j etc. This allows to you switch you actual implementation if required. — Shivam Sinha, May 23 '14 at 12:17
Yes, which is why I'm asking the question :) The server will handle the logging configuration for you so there is no reason to use an additional log manager like log4j. — James R. Perkins, May 23 '14 at 19:52
Well the server logs weren't displaying anything even after adding the logger category to standalone.xml ..Hence I thought I would need to explicitly define the implementation. — Shivam Sinha, May 24 '14 at 07:28
Not sure what that could be, but I have heard of the issue with Spring before. I have no idea what Spring does to configure logging, but I think it attempts to do something. — James R. Perkins, May 27 '14 at 21:40

In my case I have followed below steps and it worked for me:

Configure log4j in JBOSS EAP7.x module like below screen.

module.xml

<module name="log4j" xmlns="urn:jboss:module:1.5">
    <properties>
        <property name="jboss.api" value="unsupported"/>
    </properties>

    <resources>
        <resource-root path="log4j-1.2.17.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

Place jboss-deployment-structure.xml file under WEB-INF

Place the log4j.properties file under src-->main-->resources
Build the project and deploy it again it should work like a charm!
