Actor Producer Extension backed by the Simple Injector Dependency Injection Container for the Akka.NET framework.
Akka.DI.SimpleInjector is an ActorSystem extension for the Akka.NET framework that provides an alternative to the basic capabilities of Props when you have Actors with multiple dependencies.
If Simple Injector is your IoC container of choice and your actors have dependencies that make using the factory method provided by Props prohibitive and code maintenance is an important concern then this is the extension for you.
The best way to understand how to use it is by example. If you are already considering this extension then we will assume that you know how how to use the Simple Injector container. This example is demonstrating a system using ConsistentHashing routing along with this extension.
Start by creating your container and registering your actors and dependencies.
// Setup Simple Injector
var container = new Container();
container.Register<IWorkerService, WorkerService>();
container.Register<ITypedWorker, TypedWorker>();Next you have to create your ActorSystem and inject that system reference along with the container reference into a new instance of the SimpleInjectorDependencyResolver.
// Create the ActorSystem
using (var system = ActorSystem.Create("MySystem"))
{
// Create the dependency resolver
IDependencyResolver resolver = new SimpleInjectorDependencyResolver(container, system);
// we'll fill in the rest in the following steps
}To register the actors with the system use method Akka.Actor.Props Create<TActor>() of the IDependencyResolver interface implemented by the SimpleInjectorDependencyResolver.
// Register the actors with the system
system.ActorOf(resolver.Create<TypedWorker>(), "Worker1");
system.ActorOf(resolver.Create<TypedWorker>(), "Worker2");Finally create your router, message and send the message to the router.
// Create the router
IActorRef router = system.ActorOf(Props.Empty.WithRouter(new ConsistentHashingGroup(config)));
// Create the message to send
TypedActorMessage message = new TypedActorMessage
{
Id = 1,
Name = Guid.NewGuid().ToString()
};
// Send the message to the router
router.Tell(message);The resulting code should look similar to the the following:
// Setup Simple Injector
var container = new Container();
container.Register<IWorkerService, WorkerService>();
container.Register<ITypedWorker, TypedWorker>();
// Create the ActorSystem
using (var system = ActorSystem.Create("MySystem"))
{
// Create the dependency resolver
IDependencyResolver resolver = new SimpleInjectorDependencyResolver(container, system);
// Register the actors with the system
system.ActorOf(resolver.Create<TypedWorker>(), "Worker1");
system.ActorOf(resolver.Create<TypedWorker>(), "Worker2");
// Create the router
IActorRef router = system.ActorOf(Props.Empty.WithRouter(new ConsistentHashingGroup(config)));
// Create the message to send
TypedActorMessage message = new TypedActorMessage
{
Id = 1,
Name = Guid.NewGuid().ToString()
};
// Send the message to the router
router.Tell(message);
