Hibernate, Spring, Dao getSession() NullPointerException

I get the error.

at org.springframework.orm.hibernate3.support.HibernateDaoSupport.getSession(HibernateDaoSupport.java:143)
at com.walladverts.model.dao.UserDao.findByUsername(UserDao.java:25)

while accessing getSession() in findByUsername

package com.walladverts.model.dao;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;
import com.walladverts.exceptions.DataNotFoundException;
import com.walladverts.model.entities.User;
import com.walladverts.util.CustomHibernateDaoSupport;@
public class UserDao extends CustomHibernateDaoSupport {
    public void save(User user) {
    public void delete(User user) {
    public User findByUsername(String username) throws DataNotFoundException {
        Session session = getSession();
        Criteria crit = session.createCriteria(User.class);
        crit.add(Restrictions.eq("username", username));
        List < User > users = crit.list();
        if (users.size() < 1) {
            throw new DataNotFoundException();
        return users.get(0);

Parent class:

package com.walladverts.util;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport {@
    public void init(SessionFactory factory) {

Does anybody has an idea why this occurs? It freezes me for developing.


It happens when Spring Secure tries to sign in an user. Also my SessionFactory is working OK when calling this method from Controller.


public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport {
    private SessionFactory sessionFactory´╝Ť

    public Session getSession() {
        return sessionFactory.getCurrentSession();

public User findByUsername(String username) throws DataNotFoundException {
     Session session = getSession();
     // do sth
