Question

I am using spring/hibernate stand alone application. if i dont configure Transactions i am getting below excpetion.

Exception in thread "Thread-1" org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

in spring/hibernate integrated application is it mandatory to have transaction configuration?

Thanks!

Basically, yes. The Hibernate documentation says:

Database, or system, transaction boundaries are always necessary. No
communication with the database can occur outside of a database
transaction (this seems to confuse many developers who are used to the
auto-commit mode). Always use clear transaction boundaries, even for
read-only operations. Depending on your isolation level and database
capabilities this might not be required, but there is no downside if
you always demarcate transactions explicitly. Certainly, a single
database transaction is going to perform better than many small
transactions, even for reading data.
