trait DiagnosticActorLogging extends Actor
Scala API: Mix in DiagnosticActorLogging into your Actor to easily obtain a reference to a logger with MDC support, which is available under the name "log". In the example bellow "the one who knocks" will be available under the key "iam" for using it in the logback pattern.
class MyActor extends Actor with DiagnosticActorLogging { override def mdc(currentMessage: Any): MDC = { Map("iam", "the one who knocks") } def receive = { case "pigdog" => log.info("We've got yet another pigdog on our hands") } }
