public class MarkSagaResourceInjection extends org.openrewrite.Recipe
Leaves a // TODO(axon4to5): marker wherever an Axon Framework 4 Saga relies on resource injection, which the Axoniq Framework legacy module does not port.

Axon Framework 4 injected collaborators into @Autowired or @Inject fields of a Saga instance through a ResourceInjector. Axon Framework 5 resolves those collaborators as parameters of the @SagaEventHandler or @DeadlineHandler method instead. Which handlers need which collaborator is a decision this recipe does not take, so it marks the two places that need manual work:

  • an @Autowired or @Inject field of a Saga, being a class with a @SagaEventHandler method or the Spring @Saga stereotype;
  • a class member, or a class declaration, that uses one of the Axon Framework 4 ResourceInjector types, or that calls configureResourceInjector(..) or registerResourceInjector(..).
A CommandGateway field is not marked when it runs after MigrateCommandGatewayInSagaEventHandler, which already replaces that field with a handler parameter. The recipe is idempotent: a member that already carries the marker is left alone.
