Best practices for Spring ORM and transaction module in an application

The following are the practices that we have to follow in the design and development of an application:

Avoid using Spring's HibernateTemplate helper class in the DAO implementation, and use SessionFactory and EntityManager in your application. Because of the contextual session capability of Hibernate, use SessionFactory directly in your DAOs. Additionally, use getCurrentSession() method to access the transactional current session in order to perform persistence operations in the application. Please refer to the following code:

    @Repository 
    public class HibernateAccountRepository implements 
    AccountRepository { 
      SessionFactory sessionFactory; 
      public HibernateAccountRepository(SessionFactory 
      sessionFactory) { 
        super(); 
        this.sessionFactory = sessionFactory; 
      } 
     //... 
   } 

In your application, always use the @Repository annotation for data access objects or repositories...
