[Springframework-developer] avoiding direct dependecy on Hibernate

[dosapati <dos...@ge...>]

Hi,

I read the article on 'Data Access with the Spring Framework' at
hibernate.org.

Can we completely eliminate Hibernate SessionFactory and Session usage in
my classes[ProductDaoImpl in the article] using AOP interceptors. If I want
to use
Sun-JDO implementation in place of Hibernate as persistence manger. How many
changes do I need to make to the ProductDaoImpl class?


Before reading this article I wrote a wrapper class which will have save(),
update(),
delete() which in turn calls actual Hibernate Session to save, update
and delete the passed objects respectively. And also the wrapper class have
a method
load(), which will call Session.load(Class, ID) to load the object.

In my entity class I'll make calls to the above wrapper class. This way I am
avoiding the direct
dependency on Hibernate in my entity classes. The wrapper class has a method
to create
Session object and stores it in ThreadLocal. So that all the next requests
will use the stored
Session object. And the wrapper class has a method to close the Session
object.
But everytime I need to make these calls createSession() and closeSession()
of Wrapper class
to start a Session and close the session in a transaction. Can this be
decalrativley achieved using
Spring Framework.

Thanks in advance!
