You should not do session.getTransaction().commit();this, the @transactional will take care of it. Remove it, you should be fine.
你不应该这样做session.getTransaction().commit();，@transactional 会处理它。删除它，你应该没问题。

where you begin the transaction. i can't see this line session.beginTrainsaction(); once you begin the transaction then only you can commit and rollback
您开始交易的地方。我看不到这一行 session.beginTrainsaction(); 一旦您开始事务，那么只有您可以提交和回滚
