Off WARN logs of a class

How can i off the warn logs of a particular class(com.service.infra) in my log4j.properties.

log4j.rootLogger=DEBUG,QuietAppender,SilentAppender,LoudAppender
log4j.appender.QuietAppender=org.apache.log4j.RollingFileAppender
log4j.appender.QuietAppender.Threshold=WARN
log4j.appender.QuietAppender.File=/Log/front-log
log4j.appender.QuietAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.QuietAppender.layout.ConversionPattern= %m%n


log4j.appender.SilentAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.SilentAppender.Threshold=INFO
log4j.appender.SilentAppender.File=/par/info,infoLog
log4j.appender.SilentAppender.DatePattern='.'dd-MM-yy
log4j.appender.SilentAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.SilentAppender.layout.ConversionPattern=%d{dd/MM/yy kk:mm:ss.SSS} %-3p [%t] %x (%F:%L) - %m%n

Here, i want to turn off warn logs in my info log file /par/info,infoLog, But for warn log file it should be logged to a file /Log/front-log

You have to reference Log4j Log Level. Here example for that. Warnning log of Class3 will be off because of Log Level is used ERROR .

log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">
    <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 [%c] %m%n"/>
        </layout>
    </appender>
    <appender name="APPLICATION" class="org.apache.log4j.DailyRollingFileAppender">
        <param name="file" value="/ACE-MRBS/application.log"/>
        <param name="MaxBackupIndex" value="10"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss,SSS} |%5p| [%c] | %m%n"/>
        </layout>
    </appender>
    <root>
        <appender-ref ref="CONSOLE"/>
    </root>
    <logger name="your.app.test.Class1" additivity="false">
        <level value="DEBUG"/>
        <appender-ref ref="APPLICATION"/>
    </logger>
    <logger name="your.app.test.Class2" additivity="false">
        <level value="WARN"/>
        <appender-ref ref="APPLICATION"/>
    </logger>
    <logger name="your.app.test.Class3" additivity="false">
        <level value="ERROR"/>
        <appender-ref ref="APPLICATION"/>
    </logger>
</log4j:configuration>

This is achieved by using the following code

log4j.rootLogger=DEBUG,LoudAppender
log4j.logger.com.service.infra.inf=INFO,SilentAppender
log4j.logger.com.service.infra._warn=WARN,QuietAppender


log4j.appender.QuietAppender=org.apache.log4j.RollingFileAppender
log4j.appender.QuietAppender.Threshold=WARN
log4j.appender.QuietAppender.File=/Log/front-log
log4j.appender.QuietAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.QuietAppender.layout.ConversionPattern= %m%n

log4j.appender.SilentAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.SilentAppender.Threshold=INFO
log4j.appender.SilentAppender.File=/par/info,infoLog
log4j.appender.SilentAppender.DatePattern='.'dd-MM-yy
log4j.appender.SilentAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.SilentAppender.layout.ConversionPattern=%d{dd/MM/yy kk:mm:ss.SSS} %-3p [%t] %x (%F:%L) - %m%n

log4j.appender.LoudAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.LoudAppender.File=/Log/debugLog
log4j.appender.LoudAppender.DatePattern='.'dd-MM-yy
log4j.appender.LoudAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.LoudAppender.layout.ConversionPattern=%d{dd/MM/yy kk:mm:ss.SSS} %-5p [%t] %x (%F:%L) - %m%n

In the configuration above.. set threshold=ERROR , this will only limit the logging to ERROR level and wont include any levels below this in the log, i.e. WARN,DEBUG,INFO etc.. 

log4j.appender.QuietAppender.Threshold=WARN

set the level of the logger for your class:

log4j.logger.com.service.infra=ERROR,QuietAppender

this will log only ERROR and up for your class
