Answer 1

Providing an implementation of InjectionResolver only helps with injection, not when resolving values for the parameters of a resource method.

At least with Jersey 2.11, you need to define a ValueFactoryProvider annotated with @Provider.

@Provider
public class MyValueFactoryProvider implements ValueFactoryProvider {

    @Inject
    private MyFactory factory;

    @Override
    public Factory getValueFactory(Parameter parameter) {
        if (parameter.getAnnotation(MyAnnotationParam.class) != null) {
            return factory;
        }

        return null;
    }

    @Override
    public PriorityType getPriority() {
        return Priority.NORMAL;
    }

}

If you also want to get the value injected in, e.g., members and constructor parameters, then InjectionResolver works well.
