问题描述
放置 @Transactional 注释时，最佳做法是什么？我应该注释接口方法还是实现？
What is considered the best practice in placing the @Transactional annotation? Should I annotate the interface method or the implementation?
推荐答案
好问题。我总是把它放在实施中。也许是因为它是一个实现细节，而不是一个抽象。
Good question. I've always put it in the implementation. Perhaps because it is an implementation detail, rather than an abstraction.
您可能希望不同的实现具有不同的交易行为。
You may want different implementations to have different transactional behaviours.
