This is a Spring Boot application that tries out configuring a Kafka listener with a Spring Expression (SpEL) as the configured Kafka topic.
The main point of this project is the
Consumer, where the
special __listener token is used in the topics SpEL to reference to the application configured
topic.
It's worth noting that the use of @Scheduled on the Producer's sendTime method did require
scheduling to be enabled with @EnableScheduling.
