Hey,
So I've just switched my logging framework to Log4j2 to leverage it's
support for MDC. Given that I've used a mixture of SLF4J and JUL log
messages within my code I've decided to leverage Log4j ability to
convert JUL log messages to Log4j2 messages. I've set the following flag
to my application
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager and
added all the required jars. Logging seems to be working pretty good in
that my SLF4J and JUL messages are being formatted according to my
log4j2 config file I added a Hello prefix to each message, though MDC
seems to not be picked up with the JUL messages.
From debugging when I use the SLF4J logger it calls Log4jLogger which
is preserving the ThreadContext whereas my JUL log messages are
re-initializing the ThreadContext as soon as they enter AbstractLogger.
Anyone know if it's possible to preserve ThreadContext with JUL messages
being converted to Log4j2 messages or is there a potential alternative
method I can look into?
My Log4j2.xml config file:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="Hello %X{Organisation}
%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>

Abdul Haseeb Hussain
