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
