这是我在servlet-context-xml中的bean

当我启动服务器时抛出此异常：

这是我的DAO：
@Repository
@SuppressWarnings({"unchecked", "rawtypes"})
public class TimbreDAOImpl {
@Autowired private SessionFactory sessionFactory;
private Session session;
@Transactional
public List<Timbre> findAll() {
Transaction tx = null;
session = sessionFactory.getCurrentSession();
try {
tx = session.beginTransaction();
List timbres = session.createQuery("from Timbre").list();
tx.commit();
return timbres;
} catch (Exception e) {
// TODO: handle exception
if (tx != null) tx.rollback();
e.printStackTrace();
return null;
}
}
@Transactional
public List<Formato> findAllFormatos() {
Transaction tx = null;
session = sessionFactory.getCurrentSession();
try {
tx = session.beginTransaction();
List<Formato> formatos = session.createQuery("from formato").list();
System.out.println("Pase :'D");
tx.commit();
return formatos;
} catch (Exception e) {
// TODO: handle exception
if (tx != null) tx.rollback();
e.printStackTrace();
return null;
}
}
@Transactional
public boolean addTimbre(Timbre t){
Transaction tx = null;
session = sessionFactory.getCurrentSession();
try {

session.save(t);
tx.commit();
return true;
} catch (Exception e) {
// TODO: handle exception

return false;
}
}
@Transactional
public Timbre searchTimbre(int idTimbre){
Transaction tx = null;
session = sessionFactory.getCurrentSession();
try {

Timbre t = (Timbre) session.get(Pizza.class, idTimbre);
tx.commit();
return t;
} catch (Exception e) {

if (tx != null) tx.rollback();
e.printStackTrace();
return null;
}
}
@Transactional
public boolean deleteTimbre(int id){
Transaction tx = null;
session = sessionFactory.getCurrentSession();
try {

session.delete(searchTimbre(id));
tx.commit();
return true;
} catch (Exception e) {

}
@Transactional

每个对象映射如下：
package com.mufi.objeto;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="Almacen")
public class Almacen implements Serializable{
/**
*
*/
private static final long serialVersionUID = -5855838969946740041L;
@Id
@Column(name="idAlmacen")
@GeneratedValue
private int idAlmacen;
@Column(name="nombre")
private String nombre;
@Column(name="descripcion")
private String descripcion;
public Almacen(){
}
我认为问题出现在servlet-context.xml中，但我不知道可能是什么，这件事我也不明白：持久化类未知：int，因为int是本机类型java，我看到像Product或User这样的对象的问题，但从未使用过int或String或Double等等。
