My expectation would be no (though on preview it looks like Willi might
disagree, so a test seems in order!). I think what you actually want is:
bind(FooCompmentImpl.class).annotatedWith(Names.named("1")).in(Scopes.SINGLETON);
bind(FooCompmentImpl.class).annotatedWith(Names.named("2")).in(Scopes.SINGLETON);
bind(FooCompmentImpl.class).annotatedWith(Names.named("3")).in(Scopes.SINGLETON);
bind(FooComponent.class).annotatedWith(Names.named("1").to(Key.get(FooComponentImpl.class,
Names.named("1"));
bind(FooComponent.class).annotatedWith(Names.named("2").to(Key.get(FooComponentImpl.class,
Names.named("2"));
bind(FooComponent.class).annotatedWith(Names.named("3").to(Key.get(FooComponentImpl.class,
Names.named("3"));
Otherwise you'll have an unannotated, unscoped binding of FooComponent to
FooComponentImpl, along with three singleton-scoped bindings with different
annotations for FooComponentImpl. Attempting to inject an annotated
FooComponent into your ModelImpl in that case will fail.
Cheers,
