```
public interface KafkaListenerConfigurer
```
Optional interface to be implemented by Spring managed bean willing to customize how Kafka listener endpoints are configured. Typically used to defined the default KafkaListenerContainerFactory to use or for registering Kafka endpoints in a programmatic fashion as opposed to the declarative approach of using the @KafkaListener annotation.
