ich ein Projekt mit SQL Server erstellt haben, die die Dateien:falsche Syntax nahe dem Schlüsselwort 'Tabelle' und konnte nicht extrahieren ResultSet
UserDAO.java *
public class UserDAO
{
private static SessionFactory sessionFactory;
static
{
sessionFactory = HibernateUtility.getSessionFactory();
}
@SuppressWarnings("unchecked")
public static List<User> findAll()
{
Session session = sessionFactory.openSession();
Criteria crit = session.createCriteria(User.class);
List<User> userList = crit.list();
return userList;
}
}
UserService.java
public class UserService
{
public static void main(String[] args)
{
List<User> listUsers = UserDAO.findAll();
for(User u : listUsers)
{
System.out.println("User is = " + u.getUserName());
}
}
}

Jede Hilfe sehr geschätzt wird. Danke im Voraus.
Verwenden Sie eckige Klammern (z. B. '[Benutzer]' anstelle von 'Benutzer'). Ich würde vorschlagen, nicht "Benutzer" für einen Tabellennamen zu verwenden, da es ein reserviertes Schlüsselwort in SQL ist. – ZLK
Vielen Dank ZLK für Ihre Hilfe, es ist gelöst. – saria
