How do I bind Different Interfaces using Google Guice?

Question

Do I need to create a new module with the Interface bound to a different implementation?

Chef newChef = Guice.createInjector(Stage.DEVELOPMENT, new Module()          


        

Answer 1

How do you decide which FortuneService implementation is required for Chef?You can not bind the same interface to different implementations without a way for Guice to differentiate between the two. You have to use something like this.

bind(FortuneService.class).annotatedWith(Names.named("1").to(FortuneServiceImpl.class);
bind(FortuneService.class).annotatedWith(Names.named("2").to(FortuneServiceImpl2.class);
