automatic dependency injection

[Luiz E. Kowaslki]

hi all
i'm pretty much new in guice, and now i have some questions.
i'm working on an RCP app (OSGi) and i'm using guice and peaberry
my activator is like this
Module mod = new AbstractModule() {

@Override
protected void configure() {
install(Peaberry.osgiModule(context));
}
};

injector = Guice.createInjector(mod, new GermantechModulo());

and this germantechmodulo


public class GermantechModulo extends AbstractModule {

@Override
protected void configure() {
bind(DAO.class).to(DAOImpl.class).in(Scopes.SINGLETON);
}

@Provides
public EntityManager getEntityManger(){
return ECFEntityManager.createEntityManager();
}

as you can see, in my 'configure()' I bind my dao (interface) to my
daoimpl...but i'll have a LOT of daos and repositories.
is there a way to tell guice to 'auto bind' these classes?
thanks a lot

In your case, how would Guice know what to bind?

i think i can use some annotation like @Repository or some other
convention, like spring's ClassPathScanningCandidateComponentProvider

There are a number of extensions / utilities that can scan annotations and bind implementations:

http://groups.google.com/group/google-guice/search?q=annotation+scanner&start=0&scoring=d&

and if you need special scanning it's not hard to write your own using something like http://code.google.com/p/reflections/ as a base - then it's just a matter of calling the Guice SPI just as before, except that this time you're looping over the results and calling "bind( clazz )..." rather than "bind( MyDAO.class )..."

HTH
