SessionFactory returns same object everytime we call it?

[Nishita Jain]

Hi,

I want to know that if we call
SessionFactory sessionFactory = new Configuration().configure().buildSessionfactory();
n number of times in our project wil it retun same object? if yes then how?
I know that SessionFactory objects are immutable and object is return based on the given config params.

Thanks,

Creating a new SessionFactory is a heavy weight operation, you should not be doing it more than once in your application.

If the SessionFactory uses an external configuration file and this changes then the object content will be different.

From a functional standpoint, you'll get 'the same object' in the sense that it will do 'the same thing.' However, from a Java/JVM perspective, it is not the same instance, but a completely new object.

Your JVM won't start spitting out errors if you do this, but it's not a good practice, and really only has drawbacks, as opposed to any real benefits.
