All Implemented Interfaces:
Cloneable
public class AddEntityCreatorAnnotation extends org.openrewrite.Recipe
Adds the @EntityCreator annotation to existing no-arg constructors of classes annotated with either @EventSourcedEntity (free AF5) or the Spring stereotype @EventSourced.

Axon Framework 5 makes @EntityCreator mandatory for entity instantiation. The migration guide recommends the no-arg constructor pattern for most existing aggregates: the framework creates an empty instance, and the identifier and other state is initialized in the @EventSourcingHandler of the creation event — exactly the pattern AF4 users already had with their default-constructor-plus-event-sourcing-handler setup.

Idempotent — constructors that already carry @EntityCreator are left alone.
