Aggregate id in @EventHandler

Hi all,

Quick question, in the a @EventHandler method from a “Projector” how can i get the AggregateId??
I have seen that if i put as input a EventMessage type i get the wrapper for the event but i don’t find a way to get the aggregate id if i don’t put it inside the event payload, there exist any way?

Best Regards

Hi Jorge,

Instead of

public void on(EventA event) {

you can do:

public void on(DomainEventMessage eventMessage) {

EventMessages in don’t always have an aggregate identifier (that’s why you weren’t able to find it) - this is only the case for DomainEventMessages. On DomainEventMessage, you can call getAggregateIdentifier().

Kind regards,

Works perfectly thanks!!
