在Guice中注入一个对象数组

public interface MyService {
    void doSomething();
}

public class ServiceA implements MyService {
    @Override
    public void doSomething() {
        System.out.println("Service A is doing something");
    }
}

public class ServiceB implements MyService {
    @Override
    public void doSomething() {
        System.out.println("Service B is doing something");
    }
}

public class MyModule extends AbstractModule {
    @Override
    protected void configure() {
        Multibinder<MyService> myServiceSetBinder = Multibinder.newSetBinder(binder(), MyService.class);
        myServiceSetBinder.addBinding().to(ServiceA.class);
        myServiceSetBinder.addBinding().to(ServiceB.class);
    }
}

public class MyApp {
    @Inject
    private Set<MyService> myServices;

    public void run() {
        for (MyService service : myServices) {
            service.doSomething();
        }
    }
}
