Logging - Log4j2 logging issue

Question

I am currently working on an application that is using Log4j2 for logging.

Below is the Log4j2.xml file

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug" packages="myappsystem">
<Appenders>
    <MyDockerAppender name="STDOUT" />
</Appenders>
<Loggers>
    <logger name="org.springframework" level="ERROR"/>
    <logger name="myappsystem"  level="INFO"/>
    <Root level="ERROR" additivity="true" includeLocation="true">
        <AppenderRef ref="STDOUT"/>
    </Root>
</Loggers>

Now the challenge that I am facing here is the logger seems to be logging only when I do something like below

private static final Logger LOGGER = LogManager.getLogger("myappsystem");
LOGGER.info("Entering method");

The problem here is, It is not giving me the details of the class files from which this particular line is being logged.

So, I tried to do something like below:

private static final Logger LOGGER = LogManager.getLogger(MyServiceImpl.class);

This doesn't seem to be working. Any ideas on where I am going wrong?

Answer 1

Your logger is configured for

<logger name="myappsystem"  level="INFO"/>

and therefore

LogManager.getLogger("myappsystem");

works.

If you use

LogManager.getLogger(MyServiceImpl.class);

you have to configure a Logger starting with the fully qualified Classname (with packages) like you use in <logger name="org.springframework" level="ERROR"/>

So ie

<logger name="my.project.package.structure"  level="INFO"/>
