For completeness, I am putting my HibernateUtils class here as well.

{code:title=HibernateUtil.java|borderStyle=solid}

public class HibernateUtil {

private static SessionFactory sessionFactory;

public static SessionFactory getSessionFactory() {

if (sessionFactory == null) {

try {

Configuration configuration = new Configuration();

Properties settings = new Properties();

// settings.put(Environment.DRIVER, "com.mysql.cj.jdbc.Driver");

settings.put(Environment.DRIVER, "com.mysql.jdbc.Driver");

settings.put(Environment.URL, "jdbc:mysql://localhost:3306/hibernate-ix");

settings.put(Environment.USER, "my-user");

settings.put(Environment.PASS, "my-password");

settings.put(Environment.DIALECT, "org.hibernate.dialect.MySQL57Dialect");

settings.put(Environment.SHOW_SQL, "true");

configuration.setProperties(settings);

configuration.addAnnotatedClass(Person.class);

configuration.addAnnotatedClass(Child.class);

ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()

.applySettings(configuration.getProperties())

.build();

sessionFactory = configuration.buildSessionFactory(serviceRegistry);

} catch (Exception e) {

e.printStackTrace();

}

}

return sessionFactory;

}

}

{code}
