我用不同的方法做了 KafkaListenerEndpointRegistry ```
for (MessageListenerContainer messageListenerContainer : kafkaListenerEndpointRegistry.getListenerContainers()) {
List containers = ((ConcurrentMessageListenerContainer) messageListenerContainer).getContainers();

        List<TopicPartition> topicPartitions = (List<TopicPartition>) containers.stream().flatMap(kafkaMessageListenerContainer ->
                        kafkaMessageListenerContainer.getAssignedPartitions().stream()).collect(Collectors.toList());

        partitions.addAll(topicPartitions.stream().map(TopicPartition::partition).collect(Collectors.toList()));

}

是的，你可以做：

@Bean
public ConsumerAwareRebalanceListener rebalanceListener() {
    return new ConsumerAwareRebalanceListener() { 
        @Override
        public void onPartitionsAssigned(Consumer<?, ?> consumer, Collection<TopicPartition> partitions) {
           // here partitions
        }
    };
}

然后将其添加到concurrentkafkalistenercontainerfactory

@Bean
public ConcurrentKafkaListenerContainerFactory<Object, Object> kafkaListenerContainerFactory() {
    ConcurrentKafkaListenerContainerFactory<Object, Object> factory = new ConcurrentKafkaListenerContainerFactory<>();

    ContainerProperties props = factory.getContainerProperties();
    props.setConsumerRebalanceListener(rebalanceListener());

    return factory;
}
