j'ai une classe java bean User
here are my files:
I have a class
Code:
package com.mql.vo;
/**
* @author KhadijaRSS

*/
public class User {
private int idUser;
private String login;
private String pass;
public User() {
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPass() {
return pass;
}
public void setPass(String pass) {
this.pass = pass;
}
public void setIdUser(int idUser) {
this.idUser = idUser;
}
public int getIdUser() {
return idUser;
}
}
et le ficher de mapping associé:
and the associated mapping file:
Code:
<hibernate-mapping package="com.mql.vo">
<class name="User" table="Compte">
<id name="idUser" column="idCompte">
<generator class="native"/>
</id>
<property name="login" column="login"/>
<property name="pass" column="password"/>
</class>
</hibernate-mapping>
une classe de creation d'une session hibernate:
a class to create a Hibernate session:
Code:
package com.mql.util;
import java.io.File;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
public static final SessionFactory sessionFactory;
static {
try {
// Création de la SessionFactory à partir de hibernate.cfg.xml
File f=new File("D:/JAVA/workspace/Test1Hibernate/WebContent/WEB-INF/classes/com/mql/util/hibernate.cfg.xml");
sessionFactory = new Configuration().configure(f).buildSessionFactory();
sessionFactory.openSession();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
le fichier de configuration:
configuration file:
Code:
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">
jdbc:mysql://localhost:3307/mql</property>
<property name="connection.username">root</property>
<property name="connection.password">arhid28</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->

</hibernate-configuration>
et finalement ma classe de test:
and finally my test class:
Code:
package com.mql.test;
import org.hibernate.Session;
import com.mql.util.HibernateUtil;
import com.mql.vo.User;
public class TesTHibernate {
public static void main(String[] args) {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
User user = new User();
user.setIdUser(1);
user.setLogin("khadija");
user.setPass("khadija");
session.save(user);
session.getTransaction().commit();
HibernateUtil.getSessionFactory().close();
}
}
