休眠事务承诺

Question

I am working in a spring boot app, and I have some methods that go through a list and perform multiple commits to the database through hibernate.

For example, I receive an object from the front end that the user has modified, and that object has many samples associated to it, and each sample has many tests associated to it.

In this scenario, i need to generate a copy of the object, its samples, and the tests and save them.

The issue im having is if somewhere in the middle an exception happens, hibernate only rolls back the most recent commit action. But i need to roll back everything from the start.

I am still new to using hibernate and spring, so my question is if you have a method that is performing multiple repository.save() calls (because you are saving across multiple tables) and something goes wrong, how can you roll back all the save() actions you have performed during this transaction?

Is there an annotation i can put on my function that does this for me?

Answer 1

Using the annotation bellow on method from service, should help you:

@Transactional(rollbackFor = Exception.class)

You must throw an exception somewhere in service method and the Spring will roll back the transaction if a thrown error is occurred.
