I've changed my DefaultFiller to support TypeLiteral
class DefaultFiller<From, To> extends Filler<From, To>{
private final TypeLiteral<Filler<From, To>> literal;
@Inject
public DefaultFiller(TypeLiteral<Filler<From, To>> literal){
this.literal = literal;
}
.....
}
... and now Filler has a default binding from DefaultFiller to
Filler ...
@ImplementedBy(DefaultFiller.class)
public interface Filler<From, To> {
....
}
... and my Filler client class...
public class PersonService{
@Inject
public PersonService(Filler<Person, PersonDto> filler){
...
}
...
}
... with this new configuration, I got an exception...
1) com.google.inject.TypeLiteral<guicedemo.dto.Filler<T, D>> cannot be
used as a key; It is not fully specified.
while locating guicedemo.dto.Filler<guicedemo.Person,
guicedemo.PersonDto>
for parameter 0 at guicedemo.PersonService.<init>
(PersonService.java:27)
while locating guicedemo.PersonService
How I can solve this?
Thanks in advance.
