AppFuse - Spring Hibernate - no session found for the current thread

Question

This is my problem: I started testing AppFuse in order to understand if it fits or not my needs.

So I start creating a project (AppFuse not the Light version, not the multi module project).

Then I followed the step from Persistance chapter (using Hibernate), creating my beans, daos and manager.

First try: as suggested in the guide I simply configured dao and manager using the AppFuse helper classes (GenericDaoHibernate and GenericManager). Everything works fine.

Second try: I need to create a custom Dao and a custom Manager to deal with my specific business rules ... again following the tutorial ... now I have this problem that is making me crazy:

Why ?

I put all the classes (controllers, dao, beans, managers) under the same package .webapp (.webapp.controller, *.webapp.dao, *.webapp.dao.impl, ecc)

my applicationContext.xml

My headache is growing up ...

What does your FornitoreController look like? In other words, how are you injecting the GenericManager? — Matt Raible, Jun 24 '13 at 22:33
Hi Matt, here my controller https://code.google.com/p/certificati/source/browse/trunk/src/main/java/com/alessandrodonato/webapp/controller/FornitoreController.java — AlexD, Jun 25 '13 at 07:42
As you can see in the controller, I've used Autowired before Resource. But it doesn't work. — AlexD, Jun 28 '13 at 11:50
you could try and use the generator of appfuse. (set in the pom file amp.genericCore to false although i get a wiring problem now :( — tibi, Aug 21 '13 at 19:51
my wiring problem was there because i had an old bean defenition in my xml files :( — tibi, Aug 21 '13 at 20:12
ah now i get the same: Data Access Failure No Session found for current thread; nested exception is org.hibernate.HibernateException: No Session found for current thread hope i can figure this out .... — tibi, Aug 21 '13 at 20:19
mmm my problem went away while solving an other probleme (deserializaion because i did not had my model have an @manyToOne) sory i can;t help out — tibi, Aug 21 '13 at 21:03

This may have been asked more than a year ago but I hope I could help someone.

I have had similar issue when starting out with appfuse framework. It turns out that I keep forgetting to add single argument constructor in my custom manager implementation. I think, most important part is in passing the autowired dao instance up to parent classes.

Expected custom manager implementation example:

@Service("customManager")
public class CustomManagerImpl extends GenericManagerImpl<User, Long> implements CustomManager {
    private UserDao userDao;

    @Autowired
    public CustomManagerImpl(UserDao userDao){
        super(userDao);
        this.userDao = userDao;
    }
}

Hope that helps.
