java - log4j xml configuration, write some Logger to file and console -

i having following xml config log4j 3 appenders. , want configure logger following way:

1. all messages more info written stdout , global log file appenders

2. but class oauth want have log file oauthfile

3. some classes filtered , write messages log on error level can achieved

   <logger name="application" level="error" /> 

4. some classes filtered , write messages own log file. solved additivity equal false flag.

   <logger name="mapactor" level="debug" additivity="false">      <appender-ref ref="mapactorfile" /> </logger> 

but how can solve 2nd problem. folowing configuration produces debug , error messages in stdout and! in oauthfile

<configuration> ...     <appender name="stdout" ...></appender>     <appender name="file" ...>     </appender>      <appender name="oauthfile" ...>     </appender> ... <logger name="controllers.oauth" level="debug" additivity="false">     <appender-ref ref="oauthfile" /> </logger>     <root level="info">         <appender-ref ref="stdout" />         <appender-ref ref="file" />     </root>  </configuration> 

actually have found solution second task. should make 2 stdout , file appenders - 1 general logging , second 1 filtering

<appender name="stdout" class="ch.qos.logback.core.consoleappender">     <encoder>         <pattern>%d{hh:mm:ss.sss} %coloredlevel %cyan(%logger{15}) %message%n%xexception{5}</pattern>     </encoder> </appender>  <appender name="stdouterr" class="ch.qos.logback.core.consoleappender">      <filter class="ch.qos.logback.classic.filter.thresholdfilter">         <level>warn</level>     </filter>      <encoder>         <pattern>%d{hh:mm:ss.sss} %coloredlevel %cyan(%logger{15}) %message%n%xexception{5}</pattern>     </encoder> </appender> 

and use second appender-ref classes should produce error log general stdout here:

<logger name="mapactor" level="debug" additivity="false">     <appender-ref ref="mapactorfileappender" />     <appender-ref ref="stdouterr" /> </logger>
