hibernate - 需要休眠事务回滚还是足够接近？

Question

考虑 Hibernate 中的以下（简化）场景：

Session session=sessionFactory.openSession();
Transaction tx=session.beginTransaction();
try {
    //Do something with session
    if (...) {
        return something;
    }
    tx.commit();
}
finally {
    session.close();
}

在没有显式回滚的情况下返回是否是一种安全的做法，即在代码片段中调用没有显式回滚的 session.close() 语句是否会导致最终回滚？

Not knowing how complex your real code may be, nevertheless, it is not best practice to not rollback in catch/finally. Here's how my current code looks like :

try{ .....

transaction = session.beginTransaction();  .....
// Finally commit the changes...
        transaction.commit();
}catch (Exception ex) {
        LOG.error(blah);
        transaction.rollback();
        throw new STDException("An error occured ",
                ex);
    } finally {
        session.close();
    }
