Due to historical reasons, we are using a Session-per-application pattern in our java desktop application. Loaded objects are detached after session close. After migration from 4.1.9 to 5.2.12, these objects are now detached after a transaction callback operation.
How to set the transaction scope to Extended Persistence context in Hibernate 5.2?
An object is detached only after you close the Session, not after a transaction operation. More, you can span a single Session across multiple subsequent transactions without needing to use an Extended Persistence Context.
Calling operation mySession.contains(myEntity) returns false after executing mySession.getTransaction().rollback()
Calling operation mySession.contains(myEntity) returns false after executing mySession.getTransaction().rollback()
That’s a JPA requirement. This is an excerpt from the spec:
3.3.3 Transaction Rollback
For both transaction-scoped persistence contexts and for extended persistence contexts that are joined to
the current transaction, transaction rollback causes all pre-existing managed instances and removed
instances[31] to become detached.
OK. thank you very much
