Creating a generic SessionFactory provider class

Now, we will create a helper class, which will help us to set and get SessionFactory on demand.

We require SessionFactory at every point while working with hibernate. So, we will create a HibernateUtil.java class.

Tip

This is just a naming convention and not a hibernate standard but is used globally by developers and communities for the ease of use.

How to do it…

Here, we will create a Java file with the name HibernateUtil.java:

1. Enter the following code in the HibernateUtil.java file:

   import org.hibernate.SessionFactory;
   import org.hibernate.cfg.Configuration;
   
   public class HibernateUtil {
     private static final SessionFactory sessionFactory;
       
     static {
       try {
         // Create the SessionFactory from hibernate.cfg.xml
        sessionFactory = new Configuration().configure().buildSessionFactory();
   
         // Use code below for Hibernate version 4
         // Configuration configuration = new Configuration();
         // configuration = configuration...
