A good start would be to implement what I suggest in https://issues.apache.org/jira/browse/LOG4J2-1010, add possibility to set the context map in calls to the methods in the Logger interface.
That would make it possible to implement what I need on top of Log4j 2. I can't come up with any really convenient way to do it in Java, but in Scala (which I mostly use) you can use implicit parameters and provide a wrapper like this: trait ScalaLogger { def info(message: String)(implicit context: ContextMap): Unit } On Thu, May 21, 2015 at 6:40 AM, Gary Gregory <garydgreg...@gmail.com> wrote: > Mikael, > > Any thoughts on how to get this to work for you?
