Spring Kafka - How to Retry with @KafkaListener

spring-kafka SeekToCurrentErrorHandler（如果设置了spring.kafka.listener.ack-mode=time，可以重试吗？或以指定的确认模式重试工作，例如MANUAL MANUAL_IMMEDIATE。

@Value("${${sync.kafka.header.source.id}}")
private String headerSourceId;

@Value("${sync.kafka.from.id}")
private String syncKafkaFromId;

@Value("${sync.kafka.to.id}")
private String syncKafkaToId;

@Autowired
private KafkaTemplate kafkaTemplate;

@Autowired
private ConsumerFactory consumerFactory;

@KafkaListener(topics = "${sync.kafka.topics}")
public void listen(ConsumerRecord<?, ?> record,
                   @Header(KafkaHeaders.RECEIVED_TOPIC) String topic,
                   @Header(value = KafkaHeaders.RECEIVED_MESSAGE_KEY, required = false) String messageKey,
                   @Header(value = "${sync.kafka.header.source.id}", required = false) String customHeader,
                   @Headers MessageHeaders messageHeaders) {
    log.info("- - - - - - - - - - - - - - -");
    log.info("topic: {}", topic);
    log.info("message key: {}", messageKey);
    log.info("custom header: {}", customHeader);
    log.info("messageHeaders: {}", messageHeaders);

    ProducerRecord<Object, Object> ProducerRecord = new ProducerRecord(topic,record.key(), record.value());
    ProducerRecord.headers().add(new RecordHeader(headerSourceId, syncKafkaFromId.getBytes()));

    kafkaTemplate.send(ProducerRecord);
}
@Bean
public ConcurrentKafkaListenerContainerFactory<?, ?> kafkaListenerContainerFactory(
        ConcurrentKafkaListenerContainerFactoryConfigurer configurer,
        ConsumerFactory<Object, Object> kafkaConsumerFactory) {
    ConcurrentKafkaListenerContainerFactory<Object, Object> factory = new ConcurrentKafkaListenerContainerFactory<>();
    configurer.configure(factory, kafkaConsumerFactory);
    factory.getContainerProperties().setErrorHandler(new SeekToCurrentErrorHandler());
    // or factory.setRetryTemplate(aRetryTemplate);
    // and factory.setRecoveryCallback(aRecoveryCallback);
    return factory;
}

使用SeekToCurrentErrorHandler时，只能使用手动，记录或批处理确认模式。您还应该将ackOnError容器属性设置为false，并将enable.auto.commit设置为false。

如果设置spring.kafka.listener.ack-mode = time，是否可以重试？或以指定的ack模式重试工作？
