问题描述
我有dao，它基本上用hibernate将一条记录插入到一个表中，这个dao用 @Transactional 标注 propogation-NESTED ，并且我有一些其他的东西，然后调用我的dao。我的服务也用 @Transactional 加注 propagation-REQUIRED 。
I have dao which basically inserts a record into a table using hibernate, this dao is marked by @Transactional annotation with propogation-NESTED, and I have service which makes some other stuff and then invokes my dao. My service is also annotated with @Transactional with propagation-REQUIRED.
我在循环中调用服务。我的刀片插入是否可以批量或一个一个地工作？我如何确保他们能够批量工作？ hibernateTransaction管理器是否管理批量插入？
I call service in a loop. Does my inserts on my dao works in batch or one by one? How can I be sure that they work in batch? Does hibernateTransaction manager manage batch inserts?
我使用的是Oracle DB。
I am using Oracle DB.
