• 你们有用@Transactional来控制事务是吧，那么能不能说出一些事务不生效的场景？

      1)  @Transactional annotations only work on public methods. If you have a private or protected method with this annotation there’s no (easy) way for Spring AOP to see the annotation. It doesn’t go crazy trying to find them so make sure all of your annotated methods are public.

      2) Transaction boundaries are only created when properly annotated (see above) methods are called through a Spring proxy. This means that you need to call your annotated method directly through an @Autowired bean or the transaction will never start. If you call a method on an @Autowired bean that isn’t annotated which itself calls a public method that is annotatedYOUR ANNOTATION IS IGNORED. This is because Spring AOP is only checking annotations when it first enters the @Autowired code.

      3) Never blindly trust that your @Transactional annotations are actually creating transaction boundaries. When in doubt test whether a transaction really is active (see below)
