Overview of this book

This book will provide a useful hands-on guide to Hibernate to accomplish the development of a real-time Hibernate application. We will start with the basics of Hibernate, which include setting up Hibernate – the pre-requisites and multiple ways of configuring Hibernate using Java. We will then dive deep into the fundamentals of Hibernate such as SessionFactory, session, criteria, working with objects and criteria. This will help a developer have a better understanding of how Hibernate works and what needs to be done to run a Hibernate application. Moving on, we will learn how to work with annotations, associations and collections. In the final chapters, we will see explore querying, advanced Hibernate concepts and integration with other frameworks.

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 class.


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

  1. Enter the following code in the 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...
