Hi,
I'm trying to transfer serialized java objects to an Actor.
What I want to do is to transfer a java serialised object with a key.
(Think of it is like a key value cache) The server is written with Akka
Actors and the client is Java.
On the actor side I get the "ByteString" objects, and when I immediately
send them to Java client I can read them. There is no problem with this.
The problem is, I want to know which keys and objects are received on the
actor level. But I only get ByteString, and I don't know which of them is
the key or the object. Is there kind of a delimiter which I should check,
like "now I'm receiving the key, and now I receive the related object"?
The example java code I'm using:
InetAddress address = InetAddress.getByName("127.0.0.1");
Socket socket = new Socket(address, 7000);
ObjectOutputStream outputStream = new ObjectOutputStream(socket.
getOutputStream());
outputStream.writeObject("key1");
outputStream.writeObject(user);
ObjectInputStream inputStream = new ObjectInputStream(socket.getInputStream
());
String str2 = (String)inputStream.readObject();
System.out.println("Received string2 object: "+str2);
User user2 = (User)inputStream.readObject();
System.out.println("Received user2 object: "+user2.fullName());
And my data handler is the example given on the Akka.io socket introduction:
class SimplisticHandler extends Actor with ActorLogging {
override def preStart() = {
log.info("SimplisticHandler started!")
}
def receive = {
case Received(data) =>
log.info("Received data: "+data)
sender() ! Write(data)
case PeerClosed => context.stop(self)
}
override def postStop() = {
log.info("SimplisticHandler stopped!")
}
}
