No Hibernate Exception on the same insert of data
- by Mark Estrada
Hi All,
Hibernate Newbie here. I am quite unsure why I am not getting any exception when I am executing below code. On first attempt, this code creates the Book Entry on my Book Table.
But my concern is that when I execute below code again, no error was pop out by Hibernate.
I was in fact expecting some sort of Violation of Primary Key Constraints as what I have bee doing in JDBC
code.
public class BookDao {
public void createBook(Book bookObj) {
Session session = HibernateUtil.getSessionFactory()
.getCurrentSession();
session.beginTransaction();
session.saveOrUpdate(bookObj);
session.getTransaction().commit();
}
}
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
return new AnnotationConfiguration().configure()
.buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
public class BookDBStarter {
public static void main(String[] args) {
Book bookHF = new Book();
bookHF.setIsbn("HF-12345");
bookHF.setName("Head First HTML");
bookHF.setPublishDate(new Date());
BookDao daoBook = new BookDao();
daoBook.createBook(bookHF);
}
}
Is this normal hibernate way? And how will I know if my insert is successful? Any thoughts?
