log4j:WARN No appenders could be found for logger (org.apache.catalina.startup.TldConfig).

log4j:WARN Please initialize the log4j system properly.

的问题解决：

将log4j.properties放到 \WEB-INF\classes中, 搞定。

其中log4j.properties配置如下：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<!– log4j configuration file –>

<log4j:configuration xmlns:log4j=’http://jakarta.apache.org/log4j/’>

<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">

<param name="target" value=http://zhidao.mail.163.com/zhidao/topic/"System.out" />

<param name="Threshold" value=http://zhidao.mail.163.com/zhidao/topic/"debug"/>

<layout class="org.apache.log4j.PatternLayout">

<param name="ConversionPattern" value=http://zhidao.mail.163.com/zhidao/topic/"%d{ABSOLUTE} %-5p %m%n" />

</layout>

</appender>

<!– org.apache类的log全部记录到这里来–>

<logger name="org.apache" additivity="true">

<level value=http://zhidao.mail.163.com/zhidao/topic/"info" />

<appender-ref ref="CONSOLE" />

</logger>

<logger name="com.bitfone.mprove.console" additivity="true">

<level value=http://zhidao.mail.163.com/zhidao/topic/"debug" />

<appender-ref ref="CONSOLE" />

</logger>

<!–这个地方不注释掉，好像容易引起双重logger

<root>

<priority value=http://zhidao.mail.163.com/zhidao/topic/"info"/>

<appender-ref ref="CONSOLE" />

</root>

–>

</log4j:configuration>
