Hi there, please always state which journal you're using when talking about serialization in Akka Persistence. It's up to the Journal to decide how to serialize things, it does not have to use Akka Serialization at all (!).
In your case I believe you're using the in memory-journal, thus the serializer will never kick-in, that's the purpose of the in-mem journal, it should not serialize anything, just keep the normal objects in memory. Read this docs page to understand how and why serialization works this way in persistence: http://doc.akka.io/docs/akka/snapshot/scala/persistence-schema-evolution.html#Picking_the_right_serialization_format In general, because different journals may have different capabilities (for example an SQL store may want to store things in different columns, as it's native datatypes, not binary blobs - which Akka Serialization generates), the Journal is to decide how it serializes things. If you want to test serialization locally, use the LevelDB journal plugin (it's documented here: http://doc.akka.io/docs/akka/snapshot/scala/persistence.html#Local_LevelDB_journal ) Happy hakking! -- Cheers, Konrad `ktoso` Malawski Akka @ Typesafe On 29 September 2015 at 06:09:05, pjan vandaele ([email protected]) wrote: Hi all, I'm trying to use a custom serializer for an Event using akka-persistence, but the serializer is never getting called. My configuration is as follows akka { actor { serializers { myser = "serializers.PostCreatedSerializer" } serialization-bindings { "domain.protocol.PostCreated" = myser } } } WIth the serializer as follows: class PostCreatedSerializer extends Serializer { def identifier: Int = 523010842 def includeManifest: Boolean = false def fromBinary(bytes: Array[Byte], manifest: Option[Class[_]]): AnyRef = { PostCreated(title = "reloaded") } def toBinary(obj: AnyRef): Array[Byte] = { "test".asBytes } } I know it's not doing the write thing right now, but I just want to check whether it is getting called -> title should change to "reloaded". Unfortunately, it isn't. Been spending over 6 hours trying out different configurations, but nothing seems to work. Any ideas? thanks, pjan -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
