Hibernate session thread safety issue

[Saathvik Reddy]

Hi,

I have a class with 10 methods. Each method gets an hibernate session to execute a query.
Instead of creating hibernate session in each method can i have a class variable for hibernate session and use it in all the methods? Is it going to cause any thread-safety issues?

Thanks,
Srikanth.

Yes. In fact, if you don't you loose the benefit of the first level cache.

Depending on your architecture there are a number of patterns on the hibernate site for using the session (open session in view, transaction scoped etc.) Have a read through them.
