JBoss下面部署应用的Log4j日志不能显示问题

在应用的WEB-INF目录下面增加该文件：jboss-deployment-structure.xml

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <!-- Exclusions allow you to prevent the server from automatically adding some dependencies     -->
        <exclusions>
	    <module name="org.apache.commons.logging"/>  
            <module name="org.slf4j"/> 
            <module name="org.slf4j.impl" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>
