For a topic with multiple partitions, however, a @KafkaListener can explicitly subscribe to a particular partition of a topic with an initial offset:

Since the initialOffset has been set to 0 in this listener, all the previously consumed messages from partitions 0 and 3 will be re-consumed every time this listener is initialized.

If we don't need to set the offset, we can use the partitions property of @TopicPartition annotation to set only the partitions without the offset:
