Meaning of TrasactionAttributes

[dowchen]

I found that in the TrasactionInterceptor, I could specify the transaction attributes, e.g. PROPAGATION_REQUIRED, PROPAGATION_MANDATORY, readOnly, ISOLATION_REQUIRED, etc

Can anyone provide me the exact meaning on all of those attributes?

Thanks a lot for the help! :oops:

These are standard transaction concepts. The propagation terminology follows the conventions of the EJB spec, with the addition of PROPAGATION_NESTED, which EJB does not support.

Isolation levels are as defined in the SQL standards.

See org.springframework.transaction.TransactionDefinit ion for the values Spring supports. and the mappings to standard concepts.

That's cool. Thank you very much! :oops:
