| You can also configure POJO listeners with explicit topics and partitions (and, optionally, their initial offsets). | ||
| You can configure the topic for `@KafkaListener` in three ways. You must configure the topic in one of these ways. |

| You can simply configure the topic directly by name. In this case, you can also configure the multiple topics like `topics = {"myTopic1", myTopic2"}`. |

| You can also configure topics using topicPattern, which enables topic subscription based on a regular expression. | ||
|
|
||
| When you configure topics using either of these ways (topic or topic pattern), Kafka automatically assigns partitions according to the consumer group. Alternatively, you can configure POJO listeners with explicit topics and partitions (and, optionally, their initial offsets). |

Previously, the documentation only described manual topic partition assignment for @KafkaListener. I added information on how to configure it using by topics and topicPartitions. Thanks.
