问一个关于 springmvc 配置多模块 log4j 的配置文件失效的问题

[cgh]

举个例子，我有 A,B,C 三个项目。A 的日志级别是 warn，B,C 的日志级别默认是 Debug，此时 A 依赖了 B,C 这两个项目。
1：在启动 A 项目的时候，我希望所有输出的日志级别都是 warn，改怎么做？
2：在实际的项目中我的启动项目会依赖很多子项目。我想通过配置启动项目的日志级别来覆盖掉所有的子项目的日志级别，这该怎么做？
在线等。。。。。。。。。。。。。。。。。。

下面是启动项目的 log4j.properties 文件信息

log4j.rootLogger=warn,error,out,stdout

log4j.appender.out=org.apache.log4j.DailyRollingFileAppender
log4j.appender.out.File=test/logs/out.log
log4j.appender.out.Append = true
log4j.appender.out.Threshold = info
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %-20.25c{1} - %m%n

log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.File=test/logs/err.log
log4j.appender.error.Append = true
log4j.appender.error.Threshold = ERROR
log4j.appender.error.layout=org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %-20.25c{1} - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %-20.25c{1} - %m%n


# 屏蔽 dubbo,zookeeper,quartzScheduler,redis 等 log
log4j.logger.org.apache.zookeeper=WARN
log4j.logger.com.alibaba.dubbo=WARN
log4j.logger.cn.com.black.service.zk.lock.LockZookeeperClientFactory=WARN
log4j.logger.org.quartz.core.QuartzSchedulerThread=WARN
log4j.logger.org.I0Itec.zkclient=WARN
log4j.logger.org.springframework.data.redis=WARN
log4j.logger.com.black.kafka=WARN
log4j.logger.org.apache.kafka=WARN


下面是 web.xml 关于 log4j 的配置信息
<listener>
<description>log4j 监听器</description>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:property/log4j.properties</param-value>
</context-param>
<context-param>
<param-name>loggingLevel</param-name>
<param-value>warn</param-value>
</context-param>

<listener>
<description>Spring 监听器</description>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

项目启动后控制台信息
