This is an anti-pattern of opening and closing a Session for each database call in a single thread.It is also an anti-pattern in terms of database transactions.Group your database calls into a planned sequence.In the same way, do not auto-commit after every SQL statement in your application.Hibernate disables or expects the application server to disable, auto-commit mode immediately.Database transactions are never optional.All communication with a database must be encapsulated by a transaction.Avoid auto-commit behavior for reading data because many small transactions are unlikely to perform better than one clearly-defined unit of work, and are more difficult to maintain and extend.
