Because you've specified "annotatedWith(ToDot.class)". But when you
getting instance through injector, as a key you are using an interface
only.
You may try:
class Test {
@Inject @ToDot
IDrawGraphService drawDotService;
public Test () {
Injector drawGraphInjector = Guice.createInjector(new DrawModule());
drawGraphInjector.injectMembers(this);
drawDotService.draw(); ///or whatever
}
}
