Spring Transaction Management or Hibernate Transactions?

[biguniverse]

Hello. I'm developing a web app using Spring MVC + Spring IoC + Hibernate.

Should I use Hibernate's Transaction directly (i.e. beginTransaction and commit) or use Spring's Transaction Management?

Is one better for single databases versus across tiers?

Using Spring to manage your transactions declaratively is probably more flexible. Spring just uses Hibernate Transactions underneath (but you can also easily scale upto JTA if needed).

Spring can handle distributed transactions as well (as can Hibernate). See the reference: Do you need an application server for transaction management?
