Spring @Repository annotation does not work but @Service annotation does?
I have a simple Class called BeaconDao
package za.co.idealize.dao.impl;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import za.co.idealize.dao.BaseDao;
import za.co.idealizeit.model.Beacon;
@Service("beaconDao")
public class BeaconDao extends BaseDao{
@Autowired
protected BeaconDao(@Qualifier("sessionFactory") SessionFactory sessionFactory) {
super(sessionFactory, Beacon.class);
}
@Transactional(readOnly = true)
@SuppressWarnings("unchecked")
public List findByStoreID(int storeID) {
Session session = getSession();
Transaction tx = session.beginTransaction();
Query q = session.createQuery(
"FROM Beacon b where b.storeId = :id");
q.setParameter("id",storeID);
List beacon = q.list();
tx.commit();
return beacon;
}
@SuppressWarnings("unchecked")
public List findByUUID(String UUID) {
Session session = getSession();
Transaction tx = session.beginTransaction();
List beacon = session.createQuery(
"FROM Beacon where Beacon.Uuid = " + UUID).list();
tx.commit();
return beacon;
}
}
Whenever i start my application up with the beaconDAO marked @Repository the application comes back with the following stack trace:
SEVERE: Context initialization failed

however when i mark the beaconDao with @Service or @Component everything works perfectly fine. Can anyone see an issue here?

The problem lies entirely elsewhere:
Can not set za.co.idealize.dao.impl.BeaconDao field za.co.idealize.controller.BeaconJsonController.beaconDao to com.sun.proxy.$Proxy30.
Now, if I were to translate that to English then the translation would be: Spring cannot set beaconDao field on za.co.idealize.controller.BeaconJsonController singleton because JDK proxies are used and you have declared the BeaconJsonController.beaconDao as BeaconDao class when you should have used some kind of interface. I suspect your BeaconDao class hierarchy looks someting like BeaconDao -> BaseDao -> ISomeDao where ISomeDao is an interface. Change the declaration in BeaconJsonController from
private BeaconDao beaconDao;
to
private ISomeDao beaconDao;
and use qualifier if you must.
The problem is that Spring will create proxy for ISomeDao interface rather than for BeaconDao and you then tries to assign ISomeDao proxy to BeaconDao field which causes the class cast exception.
