Since you're using the xml properties, set up 2 different loggers, and
then attach filters to them.
Keep in mind that when attaching multiple filters to the same logger,
that if the statement fails one filter, it will pass down to the next. A
denial by a filter does not necessarily mean that the message is thrown
away, the message just fails that filter and goes onto the next one
(except in the case of DenyAllFilter). Which is why it's always safest
to have a "DenyAllFilter" at the bottom of the list to catch the
stragglers.
The filters you would need for this specific project are in the log4j
package already.
e.g.
<log4j:configuration>
<appender name="infoLogsFile" class="org.apache.log4j.FileAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MM-dd-
yyyy HH:mm:ss} %-5p %c - %m%n"/>
</layout>
<param name="file" value="info_messages.log"/>
<filter class="org.apache.log4j.varia.LevelMatchFilter">
<param name="LevelToMatch" value="INFO"/>
<param name="AcceptOnMatch" value="true"/>
</filter>
<filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender>
<appender name="otherLogsFile" class="org.apache.log4j.FileAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MM-dd-
yyyy HH:mm:ss} %-5p %c - %m%n"/>
</layout>
<param name="file" value="other_messages.log"/>
<filter class="org.apache.log4j.varia.LevelMatchFilter">
<param name="LevelToMatch" value="DEBUG"/>
<param name="AcceptOnMatch" value="true"/>
</filter>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMin" value="ERROR"/>
<param name="LevelMax" value="FATAL"/>
<param name="AcceptOnMatch" value="true"/>
</filter>
<filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender>
<root>
<priority value="ALL"/>
<appender-ref ref="infoLogsFile"/>
<appender-ref ref="otherLogsFile"/>
</root>
</log4j:configuration>

Re: Default logging priorty/level of individual classes
Posted by Jacob Kjome <ho...@visi.com>.
First, you should use <level> instead of <priority>. Second, the <root> is
just a special kind of <logger>, the root one. What you want to do is set
a separate <logger> (of which, BTW, will inherit from <root> so it will use
<root>'s appender). Something like this...
<logger name="com.MyClass">
<level value="info"/>
</logger>
<root>
<level value="debug">
<appender-ref ref="xmllayout"/>
</root>
Also, normally, I set the <root> logger to a higher threshold like "warn"
and then set specific loggers to "info" or "debug".

Default logging priorty/level of individual classes
Posted by Scott Melcher <sm...@assistcorp.com>.
When my application starts I would like to default the logging
priority/level of individual classes. I know how to set the root using the
following:
...
<root>
<priority value = "debug" />
<appender-ref ref="xmllayout"/>
</root>
...
But I would like to set the default logging priority of com.myClass to INFO
as follows...(but this doesn't work)
...
<root>
<priority value = "debug" />
<priority class = "com.myClass" value ="info" />
<appender-ref ref="xmllayout"/>
</root>
...
Anyone know what I am doing incorrectly?
