I'm in the process of creating a persistence.jar that different
projects can use. The jar will mainly consist of service objects that
call daos. For example UserService will have getUser which calls a
userDao.getUser method.
I'm not so sure though that I want the external users of the jar to be
required to use Guice to bootstrap it with Guice.createInjector
(module).
I don't really mind, if at the very end point that the user's deal
with, I code typical singletons, but I still want the daos injected by
Guice.
So for example...
public class AssociateService extends BaseService {
private static final AssociateService instance = new AssociateService
();
private AssociateService() {}
public static AssociateService getInstance() {
return instance;
}
AssociateDAO associateDAO;
@Inject
public setAssociateDAO(AssociateDAO associateDAO) {
this.associateDAO = associateDAO;
}
public Associate findByDmzID(String dmzID) throws Exception {
return associateDAO.findByDmzID(dmzID);
}
//..
}
public abstract BaseService {
static {
//COULD I JUST BOOTSTRAP HERE? which will make sure that call
//to AssociateService.getInstance() will properly have the
AssociateDAO injected?
Guice.createInjector(module)
}
}
I'm just not sure the above would work out ok?
