确保调用的方法在 Spring @Transactional 边界内

Question

I'm using org.springframework.transaction.annotation.Transactional and am calling methods that I only want to be able to be called from a method annotated with @Transactional .

For reasons I won't pollute this question with, the methods I want to call as part of the transaction should never be called out with the transaction boundary and I want to enforce this.

Is there an annotation or similar I can use to ensure these methods are only able to be successfully called from a method annotated with @Transactional ?

Answer 1

In a simplest case you can use Propagation.MANDATORY (ie @Transactional(propagation=Propagation.MANDATORY) ) transactional propagation instead of default Propagation.REQUIRED .

If you use programmatic transactions then you check TransactionStatus getters - even if your propagation is REQUIRED you can verify that TransactionStatus.isNewTransaction() returns false.
