hibernate.MappingException persistent class not known

I have this exception :

org.hibernate.MappingException: persistent class not known: java.lang.Long

I'm using Hibernate 5.1.0.Final and spring-orm 4.2.4.RELEASE

My spring configuration file (spring.xml) :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</bean>
<bean id="hibernateAnnotatedSessionFactory"

    <property name="annotatedClasses">

            <value>com.ecollection.model.Adresse</value>
            <value>com.ecollection.model.Utilisateur</value>
        </list>
    </property>

    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
            <prop key="hibernate.current_session_context_class">thread</prop>
            <prop key="hibernate.show_sql">false</prop>
        </props>
    </property>

</bean>
<bean id="utilisateurDao" class="com.ecollection.dao.UtilisateurDaoImpl">
    <property name="sessionFactory" ref="hibernateAnnotatedSessionFactory" />
</bean>
<bean id="adresseDao" class="com.ecollection.dao.AdresseDaoImpl">
    <property name="sessionFactory" ref="hibernateAnnotatedSessionFactory" />
</bean>

And I have two MySQL tables, User and Address.

User = Id, Name and Firstname
Address = Id, Street, City and UserId

for UserId in my Address entitybean, I'm doing this :

@OneToOne
@JoinColumn(name="id")
public Long getIdUtilisateur() {
    return idUtilisateur;
}

You can not use a non entity as a target for OneToOne or JoinColumn, as you did here:

@OneToOne
@JoinColumn(name="id")
public Long getIdUtilisateur() {
    return idUtilisateur;
}

Instead you can use this approach for mapping Utilisateur and Address relationship:

@OneToOne
@JoinColumn(name="id")
public Utilisateur getUtilisateur() {
    return utilisateur;
}

Of course, Utilisateur should be an entity:

@Entity
public class Utilisateur { ... }
