How to customize a specific operation for Resource in JPA server

[三浦笑峰]

I want to set a unique identifier to Patient Resource when I create it.

Therefore, I want to customize Create operation for Patient Resource to add identifier.

This identifier is calculated based on Encounter Resources referencing to the Patient Resource, so I want to assign the identifier in server, not in client.

How can I do this?

PS.

Adding Resource Provider is not a good solution because I have to define operations for other resources. (https://hapifhir.io/hapi-fhir/docs/server_plain/resource_providers.html)
What I want to do is only modifying Create Operation for Patient Resource, and leave other operations in any other Resource as they originally are.

Thank you

Probably the easiest way to do this would be with an interceptor implementing the STORAGE_PRECOMMIT_RESOURCE_UPDATED pointcut.

Cheers,

James
