SessionFactory returning null in Hibernate
Question
I am beginner in Hibernate and facing problem in creation of SessionFactory ,
SessionFactoryProvider.java:
public class SessionFactoryProvider {
private static SessionFactory factory;
public static SessionFactory getFactory() {
try {
if (factory == null) {
Configuration cfg = new Configuration().configure("hibernate.cfg.xml");
factory = cfg.buildSessionFactory();
}
} catch (Exception e) {
try {
if (factory == null) {
Configuration configuration = new Configuration();
// Hibernate settings equivalent to hibernate.cfg.xml's properties
Properties property = new Properties();
property.put(Environment.DRIVER, "com.mysql.jdbc.Driver");
property.put(Environment.URL, "jdbc:mysql://localhost:3306/shopingsite");
property.put(Environment.USER, "root");
property.put(Environment.PASS, "");
property.put(Environment.DIALECT, "org.hibernate.dialect.MySQL5Dialect");
property.put(Environment.SHOW_SQL, "true");
property.put(Environment.HBM2DDL_AUTO, "update");
property.put(Environment.POOL_SIZE, 12);
configuration.setProperties(property);
configuration.addAnnotatedClass(Category.class);
configuration.addAnnotatedClass(User.class);
configuration.addAnnotatedClass(Product.class);
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties()).build();
factory = configuration.buildSessionFactory(serviceRegistry);
}
} catch (HibernateException | NullPointerException he) {
System.out.println("Both factory code Fail");
}
}
return factory;
}
public static void shutdow() {
factory.close();
}
}

The problem with your Hibernate SessionFactory has something to do with your environment. It would appear that your compile time libraries are not the same as your runtime libraries, as a method on one of the classes you use when coding isn't there when the server kicks off.
java.lang.NoSuchMethodError: org.hibernate.internal.CoreMessageLogger.debugf(Ljava/lang/String;I)V
That seems to be the big problem triggering issues with SessionFactory creation .
