Spring 4 + Hibernate 4: sessionFactory is null

I use Spring 4.1.6.RELEASE + Hibernate 4.3.8.Final. After configuring and starting my web-app on Tomcat 7 I have sessionFactory == null.

Can you write what I did wrong? Here is my sources:

Here is my DAO-layer. I create base abstract class AbstractDao for CRUD operations and child classes with specific methods.

AbstractDao.java

package org.foxresult.dao.abstraction;

import org.foxresult.dao.interfaces.GenericDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Order;
import org.springframework.beans.factory.annotation.Autowired;

import java.io.Serializable;
import java.util.List;


public abstract class AbstractDao<T, PK extends Serializable> implements GenericDao<T, PK> {

    @Autowired
    protected SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public T getByPK(PK key) {
        T entry = null;
        Session session = null;
        if (key != null)
            try {
                session = sessionFactory.openSession();
                session.clear();
                entry = (T) session.get(getClassType(), key);
            } catch (Exception sql) {
                sql.printStackTrace();
            } finally {
                closeSession(session);
            }
        return entry;
    }

    public List<T> getAll() {
        List<T> result = null;
        Session session = null;
        try {
            session = sessionFactory.openSession();
            session.clear();
            result = session.createCriteria(getClassType()).
                        addOrder(Order.asc("id")).list();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            closeSession(session);
        }
        return result;
    }


    protected void closeSession(Session session) {
        if ((session != null) && (session.isOpen())) {
            session.close();
        }
    }
}

HibernateDepartmentDao.java

package org.foxresult.dao.implementations;

import org.foxresult.dao.abstraction.AbstractDao;
import org.foxresult.dao.interfaces.DepartmentDao;
import org.foxresult.entity.Department;

@Component
public class HibernateDepartmentDao extends AbstractDao<Department, Integer> implements DepartmentDao {

    public Class<Department> getClassType() {
        return Department.class;
    }

    public Integer getPK(Department object) {
        return object.getId();
    }
}

Hope you can help me. I'm beginner in Spring. Thanks!
