Guice Integration
Guice Integration
Module stability: STABLE
All Typed Actors support dependency injection using Guice annotations (such as ‘@Inject’ etc.). The ‘TypedActorManager’ class understands Guice and will do the wiring for you.
External Guice modules
You can also plug in external Guice modules and have not-actors wired up as part of the configuration. Here is an example:
- import static akka.config.Supervision.*;
- import static akka.config.SupervisorConfig.*;
-
- TypedActorConfigurator manager = new TypedActorConfigurator();
-
- manager.configure(
- new AllForOneStrategy(new Class[]{Exception.class}, 3, 1000),
- new SuperviseTypedActor[] {
- new SuperviseTypedActor(
- Foo.class,
- FooImpl.class,
- temporary(),
- 1000),
- new SuperviseTypedActor(
- Bar.class,
- BarImpl.class,
- permanent(),
- 1000)
- })
- .addExternalGuiceModule(new AbstractModule() {
- protected void configure() {
- bind(Ext.class).to(ExtImpl.class).in(Scopes.SINGLETON);
- }})
- .configure()
- .inject()
- .supervise();
Retrieve the external Guice dependency
The external dependency can be retrieved like this:
- Ext ext = manager.getExternalDependency(Ext.class);
