Question

I use Spring + Hibernate with annotations and i got the following error :

org.hibernate.hql.ast.QuerySyntaxException: Produit is not mapped [from Produit]

it appens when i call this function :

public List<Produit> getListeProduit() {

    return sessionFactory.getCurrentSession().createQuery("from Produit").list();
}

This is my hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
    <mapping class="port.domain.Produit" />
</session-factory>     
</hibernate-configuration>

Produit class are annoted well with @Entity, @Table
ID with @Id, @Column, @GeneratedValue
The others columns with @Column

Here is my bean SessionFactory in my XXX-servlet.xml :

<bean id="sessionFactory"     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
</bean>

EDIT : Entity Code

@Entity
@Table(name="produit")
public class Produit implements Serializable{

@Id
@Column(name="produit_id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int produitId;

@Column(name="produit_nom")
private String produitNom;

public void setProduitId(int i) {
    produitId = i;
} 

public int getProduitId() {
    return produitId;
} 

public void setProduitNom(String s) {
    produitNom = s;
} 

public String getProduitNom() {
    return produitNom;
} 
}

I know there are many threads about this problem but i don’t find any correct issues.
I understand that Hibernate can’t mapped my class but i don’t know why …

Where could the problem come from ?

Thanks a lot.

Usually the problem is trivial: you should use javax.persistence.Entity instead of Hibernate-specific org.hibernate.annotations.Entity. The latter was deprecated in Hibernate in favour of JPA annotations where possible.

That’s exactly what you didn’t show, so hope it’s a lucky shot 🙂
