User Story (Required on creation):

Hi,

The following issue is about a code part in the Camunda Spring Boot Starter.

We are using custom ApplicationEvent_ in our application to control certain lifecycle aspects during the startup. This means also that we have some subsequent migrations regarding Camunda. This migration is executed after a certain event has been published. Unfortunately, Camunda already starts on the ApplicationReadyEvent (as can be seen in the {}ProcessApplicationEventPublisher{}), which is too early for us. In order to give developers more control, it would be sufficient if one could at least overwrite the beans in the CamundaBpmAutoConfiguration without using something like the {_}spring.main.allow-bean-definition-overriding{}-Setting.

It would thus be very useful if the beans in the CamundaBpmAutoConfiguration  would be marked with {}ConditionalOnMissingBean{}. This would allow easy and clean "overring" of the beans in question with custom logic.

Hi XOqoNX7,

Thank you for raising this feature request.

• I think the request is related to the Camunda Spring Boot Starter, but it would be better if you could explicitly state this in the ticket description.
• It would also be good if you could provide an example project where you demonstrate how you are currently solving this issue.

Best, Nikola

Hi Nikola,

I modified the description accordingly.

I also created a demo application for the issue: https://github.com/nils-christian/CAM-14784. Our only possibility (without the mentioned allow-bean-override-property) at the moment is to disable the Camunda auto configuration completely and replace it with a customized version.

Best regards

Hi XOqoNX7,

Thank you for the explanation and the example project. This seems like a valid feature request to me. I'll forward it for a decision and possible scheduling.

However, this ticket might not be scheduled due to a lack of development time. So I would encourage you to make a code contribution by submitting a pull request.

Best, Nikola

Hi XOqoNX7,

thanks for this proposal, I agree with Nikola here that this makes total sense in the scope of the product and would be a nice enhancement of the Starter. (y)

We will move this to our backlog and consider it in the next planning sessions. That being said, we cannot yet say if we will work on this in the near future. If you want to speed up the process, feel free to make a contribution.

We'll update the ticket with any related progress and decisions.

Best, Tobias
