ActorSelectionMessage is handled by akka.remote.serialization.MessageContainerSerializer from the akka-remote module (registered through its reference.conf) and should never be serialized by the Java serializer.

I’d guess something wrong with your config overriding that somehow. Go through your application.conf serializer configuration and double check that it is correct. You can also look at the effective config used by setting akka.log-config-on-start = on and check the logs for configured serializers.

the situation is as you mentioned. i changed application.conf file. But now i received another error when i push message from one microservice actor to other microservice actor.

UnhandledMessage(com.common.message.global.ObjectMessage@45f6cc36,Actor[akka.tcp://dispatch-actor-system@127.0.0.1:2553/user/$c#1989792206],Actor[akka://dispatch-actor-system/user/integrationMaster/$a#-419826769])

My last serializer configuration is illustrated below;

actor {
provider = “akka.cluster.ClusterActorRefProvider”

enable-additional-serialization-bindings = on
allow-java-serialization = off

serializers {
  jackson-json = "akka.serialization.jackson.JacksonJsonSerializer"
}

serialization-bindings {
  "com.common.message.db.EntityMessage" = jackson-json
  "com.common.message.db.EntityResultMessage" = jackson-json
  "com.common.message.global.ObjectMessage" = jackson-json
  "com.common.message.global.ObjectResultMessage" = jackson-json
  "com.common.message.global.jackson.JsonSerializer" = jackson-json
}

}

JsonSerializer is my marker interface

Thanks.

UnhandledMessage is published to the event bus when an actor receives a message that it does not handle, first actorref is sender second is the recipient which did not handle the message.

So in your case your anonymous child $a of integrationMaster did not handle the ObjectMessage that anonymous actor $c sent to it.
