How To Set Specific Logger Level in Log4j2

Question

With log4j1 I was able to control an individual logger level but the property statements appear to not be working with log4j2. I have the rootLogger level set to DEBUG and want to suppress the numerous debug logs coming from Authorize.net via commons-logging. I'm trying to set the level to WARN from the http headers and wire logs.

Here's the log4j doc that details configuring a logger (reference "Configuring Log4J")

This is a sample log output:

2019-01-01 17:00:01 EST DEBUG org.apache.http.headers http-outgoing-0 << Content-Type: application/xml; charset=utf-8

2019-01-01 17:05:31 EST DEBUG org.apache.http.wire http-outgoing-0 >> "    </transactionRequest>[\n]"

This is my current log4j2.properties file:

# Tell the root logger what appenders and level to use
rootLogger.level = DEBUG

rootLogger.appenderRefs = console, file
rootLogger.appenderRef.console.ref = console
rootLogger.appenderRef.file.ref = file

appenders = console, file


##### Authorize.net #####

# Controls detailed wire protocol
log4j.logger.org.apache.http.wire=WARN

# Controls headers (good for debugging)
log4j.logger.org.apache.http.headers=WARN

# Controls http context (what you are sending and geting)
log4j.logger.org.apache.http=WARN

# Controls htmlunit details
log4j.logger.com.gargoylesoftware.htmlunit=WARN


##### Console Appender #####

appender.console.name = console
appender.console.type = Console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss z} %-5p %c %m%n


##### File Appender #####

appender.file.name = file
appender.file.type = File
appender.file.fileName = mylog.log
appender.file.layout.type = PatternLayout
appender.file.layout.pattern = %d{yyyy-MM-dd HH:mm:ss z} %-5p %c %m%n

So this apparently turns out to be a problem with using or specifying logger configs in a .properties file. I switched to the new log4j2.xml format and have it working perfectly.

Tip: In the XML file you can specify a root name for a logger and the settings will apply to all sub-classed loggers. As an example

<Logger name="org.apache.http">

Will apply to any logger that has that root such as in my original question:

<Logger name="org.apache.http.wire">
            - and - 
<Logger name="org.apache.http.headers">

Here is the working log4j2.xml file that supresses all debug messages for Authorize.net. Its a good example of overriding the root logger level:

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

<Configuration>

  <Appenders>
    <Console name="console">
      <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss z} %-5p %-5level %logger - %msg%n"/>
    </Console>

    <File name="file" fileName="mylogfile.log" append="true">
      <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss z} %-5p %-5level %logger - %msg%n"/>
    </File >
  </Appenders>


  <Loggers>
    <Root level="DEBUG">
      <AppenderRef ref="console"/>
      <AppenderRef ref="file"/>
    </Root>

    <Logger name="org.apache.http" level="WARN" additivity="false">
      <AppenderRef ref="console"/>
      <AppenderRef ref="file"/>
    </Logger>

    <Logger name="net.authorize.util" level="WARN" additivity="false">
      <AppenderRef ref="console"/>
      <AppenderRef ref="file"/>
    </Logger>

    <Logger name="net.authorize.api" level="WARN" additivity="false">
      <AppenderRef ref="console"/>
      <AppenderRef ref="file"/>
    </Logger>

  </Loggers>

</Configuration>
