Akka with Java 8 lambda support - MDC

[nil...@gmail.com]

I'm testing the experimental Java 8 lambda support with akka and AbstractActor, but I cannot seem to find a way to use the MDC feature this way. With an untyped actor, I can do Logging.getLogger(this) and get a DiagnosticLoggingAdapter with MDC support. However, since AbstractActor does not extend UntypedActor, I can only get a regular LoggingAdapter, with no way to set the MDC. Am I missing something? Is it possible with AbstractActor, or do I need to switch back to using UntypedActor?

Hi,

there is Logging.apply(logSource: Actor) which you can use with AbstractActor.

Thanks! That does work. I was kind of staying away from the apply methods in the Akka classes, since I was considering them Scala specific. Is there any "danger" in using those?

No danger. They are no special from java perspective. However, by convention we have not used apply for Java APIs. I'll create a ticket to add an alias method named create for this.
