Hi Eric,
If you look at LoggerAction from the source repository, you should see
that it already does substitution.

Hello,
In AppenderAction, there is a line:
String appenderName = ec.subst(attributes.getValue(NAME_ATTRIBUTE));
In LoggerAction, this is the equivalent:
String loggerName = attributes.getValue(NAME_ATTRIBUTE);
The LoggerAction doesn't substitute from context. My guess is that there is a
good reason why properties are not substituted in logger names....? That's my
question.
Here's where this comes from:
I thought it would be nifty to route some logs via a shared properties file
(shared between the app and logback.xml config) like so:
<property resource="logbackProps.properties" />
<logger name="${customLoggerName}>
<------------this is what doesn't work because LoggerAction doesn't substitute properties
<appender-ref ref="SOME_FILE_APPENDER" />
</logger>
Then put a logger name in the logbackProps.properties file:
customLoggerName=userAuthLogger
Then in code (let's say a user authentication DAO) I could:
private static Logger authenticationlogger =
LoggerFactory.getLogger(ClassThatGetsProperties.getPropertyValueFor(ConstantsEnum.customLoggerName));
Thanks and Cheers!
Eric C
