问题
I use annotations to mark methods which should be executed in a transaction.
But, in one place I need to do transactionManager.rollback() manually, without annotation. How can I obtain transactionManager object?
回答1:
If you want to rollback the current transaction, you may use
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
Note that it doesn't rollback the transaction immediately - it sets the "rollback only" status, so transaction will be rolled back during attempt to commit.
Otherwise, if you need a programmatic transaction demaracation, you may use
TransactionTemplate, as described in 10.6 Programmatic transaction management.
Also you can obtain an instance of PlatformTransactionManager, but it's not widely used since TransactionTemplate is a recommended approach for programmatic transaction demaracation.

If your object is configured by Spring you could off course inject a transactionmanager into it...
