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="System.out" />
<param name="Threshold" value="debug"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%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="info" />
<appender-ref ref="CONSOLE" />
</logger>
<logger name="com.bitfone.mprove.console" additivity="true">
<level value="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="info"/>
<appender-ref ref="CONSOLE" />
</root>
-->
</log4j:configuration>
