Jboss7默认采用容器自己的log4j module，应用自己配置的log4j不起作用，需要应用做一些设置：

以springMVC项目为例：

1> 在WEB-INF下新建文件jboss-deployment-structure.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?><jboss-deployment-structure><deployment><exclusions><module name="org.apache.log4j" /></exclusions></deployment></jboss-deployment-structure> 

2> 在web.xml里配置

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

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

3> 在WEB-INF下新建log4j.properties

# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!
# For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.
log4j.rootLogger=INFO,logfile#log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%nlog4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=${jboss.server.log.dir}/YOURAPP.log
log4j.appender.logfile.MaxFileSize=512KB
# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

4> pom添加依赖

<dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version>
</dependency>
