Spring 事务从 NOT_SUPPORTED 到 REQUIRES_NEW 的传播

Question

I'm working on refactoring a module with an initial method annotated with @Transactional(propagation = Propagation.NOT_SUPPORTED) and this method invokes another method that has the annotation @Transactional(propagation = Propagation.REQUIRES_NEW) .

My question is, since the initial method is not creating a new transaction, the invoked method will create a new transaction?

Answer 1

Yes, the invoked method will create and run in a new transaction.

REQUIRES_NEW will always create a new transaction irrespective of transactional mode of caller method (even if caller already created a transaction).
