Spring Boot Property for Spring Kafka authExceptionRetryInterval

[cabbonizio]

Hi there I have a spring boot app that makes use of both a kafka consumer and producer. I have been able to configure mostly everything with YAML properties but one property I am coming up short is:

org.springframework.kafka.listener.ConsumerProperties.authExceptionRetryInterval (java.time.Duration)

It seems like this property should be included in the org.springframework.boot.autoconfigure.kafka.Listener static configuration class, but I don't see it. Based on the configuration of Spring Kafka, I think this should be the logical place to put it, for instance like so:

spring:
  kafka:
    listener:
      auth-exception-retry-interval: 30s
      ack-mode: record
      concurrency: 2
      client-id: sample
    retry:
      topic:
        attempts: 5
        backoff:
          delay: 5000         
    bootstrap-servers:
    - xxxxxxxxxxxxxxxxxxxxx
    producer:
      transaction-id-prefix: ${spring.application.name}			
      key-serializer: org.springframework.kafka.support.serializer.JsonSerializer
      value-serializer: org.springframework.kafka.support.serializer.JsonSerializer
      compression-type: zstd
      retries: 5
      properties:
        "[linger.ms]": 1
    consumer:
      group-id: sample
      key-deserializer: org.springframework.kafka.support.serializer.JsonDeserializer
      value-deserializer: org.springframework.kafka.support.serializer.JsonSerializer
      auto-offset-reset: latest
      properties:
        "[spring.json.trusted.packages]": com.sample
        "[spring.json.use.type.headers]": false
    properties:
      "[security.protocol]": SASL_SSL
      "[sasl.mechanism]": SCRAM-SHA-512
      "[sasl.jaas.config]": ${kafka.sasl.jaas.config}

Unless I am missing something would it be possible to add this in as an enhancement, as this allows one to go full configuration based auto-configuration without the need of defining a custom property.

many thx!
