Hi guys,

I am upgrading my application from hibernate 4.2.18 to 5.1.0. I am using current session from session factory for repeated execution in single thread. I was used to that when connection to database is lost, commit on transaction remove session from threadlocal. How to achieve similar behavior in 5.1.0. version? Because now I am obtaining same session in case of that connection to database is lost.

If the connection is lost, only the DataSource could allow you to restablish it. But in that case the transaction is lost because the transaction is bound to the underlying connection anyway.

I know that transaction is lost. In previous versions I can reuse the same thread because transaction.commit() was removing broken session from session map in ThreadLocalSessionContext in case of connection lost during commit so that next run in same thread obtained new session. Now the broken session remains in session map in ThreadLocalSessionContext. Do I have to remove (close) it explicitly or is sufficient to use new thread and session map in ThreadLocalSessionContext is cleared in background when no longer user.

I think it's better to explicitly close the Session when you get an exception. If the Session is not removed from the TLSC, then it must be an issue.
