java - 为什么 transaction.wasCommited() 返回 false？

Question

总的来说，我对 hibernate 和 java-ee 很陌生，我想知道是否有人可以告诉我为什么这段代码返回 false，即使通过查看数据库我可以看到事务实际上已提交:

    session.beginTransaction();
    session.saveOrUpdate(user);
    session.getTransaction().commit();
    return session.getTransaction().wasCommitted(); //Always false

谢谢!

Answer 1

即使提交成功，

wasCommissed() 也不必总是返回true。如果事务(明确地)通过此本地事务提交，它将返回true；否则假。

来自docs :-

wasCommitted

This method could return false even after successful invocation ofcommit(). As an example, JTA based strategies no-op on commit() callsif they did not start the transaction; in that case, they also reportwasCommitted() as false.
