@Transactional method not rolling back when surrounded by a try-catch

Question

I have a process that iterates through a list of events and saves them to a table. If a particular event throws an exception, I need to be able to rollback that event's transactions with the database without effecting the flow through the other events.

To achieve this, I have the following setup:

public class EventService
{
    public void processEvents()
    {
        List<Event> events = getEvents();

        foreach(Event event : events)
        {
            try
            {
                processEvent(event);
            }
            catch(Exception e)
            {
                // log the exception and continue processing additional events
            }
        }
    }

    @Transactional
    public void processEvent(Event event)
    {
        // Process event and insert rows into database
        // Some event will throw a runtime exception
    }
}

However, this is not rolling back the event if there is an exception thrown.

Is there a way to achieve what I'm trying to do here?

Answer 1

If you call a method within the same class, Spring AOP does not have a chance to intercept the method. Therefore the @Transactional annotation is ignored. Trying moving the processEvent method to another class that is Spring injected.
