@Transactional multiple update; commit every single query


I have 2 methods in my service

public void updateAll() {
   long[] ids = new long[] {1,2,3,4,5,6,7,8,9,10};
   for (long id : ids) {
        updateId(id);
    }
}

public updateId(long id) {
  repository.update(id);
}

Let's assume that after the 5th update I have an exception, I would like that the first 4 operations would be committed anyway.

I'm using the @Transactional annotation but if I put the annotation in both methods it doesn't work.

Do I need other parameter?? It might be propagation??

Could you show me how to set this methods?

Thank you!!


Solution

  • Just have:

    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public updateId(long id) {
    }
    

    But, the important bit, call that method from another class. i.e. move your loop out of this class.

    The transactional annotations only kick-in when that public method is called from the outside. Within the same class, calling one transactional method from another will still only use the transaction of the first method.
