Ilja,
thanks for your reply. If I create a service class like the one below, my
_userDao object is always null. This _userDao works perfectly in other parts
of my app. Do I need to inject the dao in a special way? I think the
integration into spring is the problem, because I don't know where to place
the corresponding part in the config/xml files. As I said, my knowledge of
spring is limited.
My class looks like this:
@Service
@Transactional
public class SessionDestroyedService
{
@ Autowired
private UserDao _userDao;
public void forceLogout(String sessionId)
{
if (_userDao == null)
System.out.println("SessionDestroyedService.forceLogout(): _userDao is
NULL");
else
{
System.out.println("SessionDestroyedService.forceLogout(): _userDao is
OK");
User user = _userDao.getBySessionId(sessionId);
if (user != null)
{
// do the work here...
}
}
}
}
