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>
