Hi, guys :)
In our application we have HibernateSessionFactory class,that is open and close connections. Everything is okay,but when we are updating data in the database,it doesn't changes in our application.Unfortunately, we see old data from the database.Help me,please.
Here is my HibernateSessionFactory class :

public class HibernateSessionFactory {

private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
private static org.hibernate.SessionFactory sessionFactory;

private static Configuration configuration = new Configuration();
private static ServiceRegistry serviceRegistry;

private static final Logger log = Logger.getLogger(HibernateSessionFactory.class);

static {
try {
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties())
. buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
} catch (Exception e) {
log.error("Error Creating SessionFactory",e);

}
}

private HibernateSessionFactory() {
}

public static Session getSession() throws HibernateException {
Session session = (Session) threadLocal.get();
if (session == null || !session.isOpen()) {
if (sessionFactory == null) {
rebuildSessionFactory();
}
session = (sessionFactory != null) ? sessionFactory.openSession()
: null;

threadLocal.set(session);
}
return session;
}

public static void rebuildSessionFactory() {

try {
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder(). applySettings(configuration.getProperties())
.buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
} catch (Exception e) {
log.error("Error Creating SessionFactory",e);
}
}

public static void closeSession() throws HibernateException {
Session session = (Session) threadLocal.get();
threadLocal.set(null);
if (session != null) {
session.flush();
session.close();

}
}

public static org.hibernate.SessionFactory getSessionFactory() {
return sessionFactory;
}

public static Configuration getConfiguration() {
return configuration;
}

}
