Erreur lors de la création du bean sessionFactory

Question

J'intègre Spring avec Hibernate. Cependant, quand je lance l'application que je reçois une erreur comme:

Erreur de création de haricot avec le nom « sessionFactory » défini dans le chemin classe ressource [ressources/spring.xml]: appel de la méthode d'initialisation a échoué; exception imbriquée est org.hibernate.HibernateException: Impossible d'obtenir la valeur par défaut usine Bean Validation

Mon spring.xml ressemble:

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource"> 
    <property name="driverClassName" value="org.postgresql.Driver" /> 
    <property name="url" value="jdbc:postgresql://localhost:5432/3encult" /> 
    <property name="password" value="3encult" /> 
    <property name="username" value="3encult" /> 
</bean> 

<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="myDataSource" /> 
    <property name="mappingResources"> 
     <list> 
      <value> 
       resources/User.hbm.xml 
       <!-- Project.hbm.xml ProjCF.hbm.xml Task.hbm.xml TaskCF.hbm.xml Category.hbm.xml

      </value> 
     </list> 
    </property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> 
      <prop key="hibernate.show_sql">true</prop>

      <prop key="hibernate.c3p0.minPoolSize">5</prop> 
      <!-- Especificamos el valor maximo del pool de conexiones --> 
      <prop key="hibernate.c3p0.maxPoolSize">20</prop> 
      <!-- El tiempo de vida de cada conexion del pool. --> 
      <prop key="hibernate.c3p0.timeout">600</prop> 

     </props> 
    </property> 
</bean> 

<bean id="myUserDAO" class="main.java.com.gwt.app.server.User"> 
    <property name="sesionFactory" ref="sessionFactory" /> 
</bean> 
</beans> 

Et l'injection dans la classe utilisateur est:

ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"resources/spring.xml"}); 

public void setSesionFactory(SessionFactory sesionFactory){ 
    this.sesionFactory = sesionFactory; 
    this.sesion = this.sesionFactory.openSession(); 
} 

Le stacktrace est:

Je n'utilise pas la validation. C'est la raison de ne pas inclure le pot de validation.

Je ne sais pas ce qui se passe, j'aimerais que quelqu'un puisse m'aider.

Merci!

Answer 1

Hibernate se lève throw new HibernateException("Unable to get the default Bean Validation factory", e); s'il ne peut pas accéder à Bean Validation Framework (BeanValidationActivator).

Donc je suppose que le problème est que les jarres de validation sont manquantes.

Pour Maven:

<dependency> 
     <groupId>javax.validation</groupId> 
     <artifactId>validation-api</artifactId> 
     <version>1.0.0.GA</version> 
    </dependency> 
    <dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-validator</artifactId> 
     <version>4.0.2.GA</version> 
    </dependency> 

Answer 2

Essayez d'ajouter suivante dépendances maven (ou télécharger le JAR est si vous n'utilisez Maven):

• Hibernate Validator
• Javax Validation

D'autres dépendances peuvent également être nécessaires (envisager d'utiliser Maven si vous n'êtes pas encore, pour éviter les problèmes de ce genre)

Answer 3

Essayez une fois en ajoutant cette ligne à votre fichier hibernate.cfg.xml

<property name="javax.persistence.validation.mode" value="none"/>
