HK2 equivalent Assisted Injection with FactoryModuleBuilder

Question

Thanks to migration to jersey 2 I need to migrate from guice to HK2. I have an Assisted injection approach for some of my dependencies which I couldn't get my head around to implement in HK2. It looks like it's supposed to be solved via Custom Injection Resolvers but I don't really see how. The examples are not clear enough for me..

Here is how it looks on Guice:

public interface MyFactory {
    public MyClass createMyClass(@Assisted String dynamicParameter);
    public HisClass createHisClass(@Assisted String dynamicParameter);
    ...
}

binder.install(new FactoryModuleBuilder().build(MyFactory.class));

public class MyClass {
   ...
   @Inject
   public MyClass(@Assisted String dynamicParameter, SomeService someOtherServiceInjectedAutomatically){
      ...
   }
}

How can I implement this on HK2?

Answer 1

After posting the question I thought of doing this:

public class MyFactoryImpl implements MyFactory{

   private final SomeService someService;

   @Inject
   public MyFactoryImpl(SomeService someService){
      this.someService = someService;
   }

   public MyClass createMyClass(String dynamicParameter){
      return new MyClass(dynamicParameter, someService);
   }

   ...
}
