Using REQUIRES_NEW JTA transaction type in MyBatis on Wildfly

Question

I am trying to use mybatis-cdi within Wildfly and I need to run part of method in separate transaction - see following snippet:

@Stateless
@TransactionManagement(TransactionManagementType.CONTAINER)
public class ItemService {

    @Inject
    @Mapper
    ItemMapper mapper;

    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void doSomething() {
        List<Item> items = mapper.findByTime(new Date());
        for(Item i : items) {
            update(i);
        }
    }

    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    public void update(Item item) {
        mapper.updateSomehow(item);
    }
}

Is this correct way how to do it? Is this supported with mybatis-cdi, or should it be done some different way?

Answer 1

You're not getting your expected behavior as interceptors are not applied when using a self reference in a method, for example how doSomething() calls update() directly. You would need that to occur in a separate bean to allow a separate transaction interaction.
