is CoroutineCrudRepository compatible with MDC?

[lucasgust]

when I retrieve data from a CoroutineCrudRepository, the MDC context is lost. how can this issue be resolved?

both examples here demonstrate this behavior, where the MDC context added by the request filter is lost: https://github.com/lucasgust/txwithr2dbc/blob/main/driven/persistence/src/main/kotlin/example/micronaut/txwithr2dbc/employee/adapter/EmployeeDataAccessAdapter.kt#L23

it's relatively simple to reproduce. just execute docker-compose.yml, start the application and use the following commands to trigger logs:

• find one: curl --location 'http://localhost:8080/employees/{UUID}'
• find all: curl --location 'http://localhost:8080/employees'

ps.: the solution mentioned here using withContext(MDCContext()) from kotlinx-coroutines-slf4j does not work.

Modify your filter in this way https://docs.micronaut.io/latest/guide/#httpFilterContextPropagation

[lucasgust]

@dstepanov using this filter blocks my application after calling the repository

Can you provide a reproducer?

sorry, I had implemented MdcPropagationContext incorrectly and wasn't expecting that the Map could be null (automatic Java/Kotlin conversion). it's now working properly. thanks!
