Hi to all,
I'm newbie on Axon and CQRS, but I have done quite a hard job this
week searching and reading all I found
We have a classic JPA based application, currently working under the
All examples I have found are made with Event-Sourced Aggregates.
But our bussiness case is not as related to Event-Sourcing, but to be
able to design a good API based on Commands and Events to our JPA-
based application that can scale well on the future (perhaps to the
Our JPA-based Entities can have easily 10 - 20 fields that can be
updated, changing their state (that's really common on most CRUD
applications). Imagine a screen where all 20 fields are changed.
- Should we passed all 20 fields as parameters to the command?
As written on 1.3.3 reference guide, it should be possible to
implement our Aggregate Root inheriting/extending from
AbstractJpaAggregateRoot and adding all JPA-based .
But seems that AbstractJpaAggregateRoot has not been included on the
It should be on the org.axonframework.domain package, but nothing
found there. See it as on version 0.7.x:
- Has AbstractJpaAggregateRootbeen removed?
- Is there any example of using AbstractJpaAggregateRoot and
GenericJpaRepository? It would hekp a lot, as all examples as related
to event-sourced aggregates, none based on AbstractAggregateRoot or
- What would be the easiest solution to add a command and events based
interface to our system using Axon? Perhaps is there a better
framework for just adding commands and events to a JPA-based
Thanks a lot in advance!!!
