>From your description, it seems like you are mixing layers (which will
IMO bite you later). I would suggest keeping your components as focused
as possible. When working on this type of problem, I create services
that manage each of the entities in the domain. I generally separate
user authentication from authorization / entitlement.
Here is some pseudo-code to demonstrate what I'm talking about:
UserService
- userGateway (table gateway e.g. sets of data)
- userDAO (manage single object persistence)
getUser(username,password) : UserBean ( userDAO.read(UserBean)
);
saveUser(UserBean) : Void ( userDAO.save(UserBean) )
getAll() : Query ( userGateway.getAll() )
UserDAO
read(UserBean) : UserBean
save(UserBean) : Void
UserGateway
getAll() {
select ... from ...
return query;
}
AuthenticationService
- UserService (access to the user)
- SessionFacade (access to the session)
processLogin(username,password) : Boolean {
user = UserService.getUser(username,password);
return authenticateUser(user);
}
authenticateUser(UserBean) {
log in user.
if (loggedIn ) {
sessionFacade.setUser(UserBean);
}
return UserBean;
}
EntitlementService
- UserService
- SessionFacade
getEntitlements(UserBean)
...
In this type of a setup, you could create accessors
(setUserFacade/getUserFacade) for each of the composited items and let
CS inject them.
