you can achieve that with a Multibindings [1] and MapBinder [2]
In your module:
public void configure() {
MapBinder<String, Service> mapbinder = MapBinder.newMapBinder(binder(),
String.class, Service.class);
mapbinder.addBinding(SitemapListService.class.getName()).to(SitemapListService.class)
// if you do it this way SitemapListService wil be also injected
mapbinder.addBinding(SitemapService.class.getName()).to(SitemapService.
class)
// and so on
}
Now in your client code you can inject the map of services:
@Inject
Foo(Map<String, Service> services>) {
this.services = services;
}
