Thank you all for the great replies,
I wanted to use IoC concept to avoid having dependencies hard-coded in
my class (at least this what I thought).
Having something like :
CustomerServiceConsumer(CustomerAccountsServiceConsumer
accountConsumer, CustomerCreditCardsServiceConsumer
creditCardConsumer) { ... }
Makes little sense to me as the class have to change every time I need
to have more dependencies .
let me try to be more clear ,
public class CustomerServiceConsumer extends ServiceConsumer<Client>{
@Override
public void consume() {
// consume code for client goes here
// Then load dependencies
for (ServiceConsumer<?> d:getDependencies()){
d.consume();
}
}
@Inject
@Override
public List<ServiceConsumer<?>> getDependencies() {
// ...
}
}
Now I want the getDependencies() to return the other 2 (or more)
services and I want to be able to glue them outside the class
CustomerServiceConsumer .
@Thomas I think you MultiBinder is what I need but I'm using GIN and
it's not supported :(
Any other suggestions ?
