java中从kafka队列中消费数据，如何保证数据不丢失？

@KafkaListener(topics = "order-topic", groupId = "payment-group")
public void listen(
    ConsumerRecord<String, String> record,
    Acknowledgment ack,
    Consumer<String, String> consumer) {
    try {
        paymentService.process(record.value());
        ack.acknowledge(); // 手动提交
    } catch (Exception ex) {
        // 记录原始消息到死信队列
        kafkaTemplate.send("order-dlq", record.key(), record.value());
        // 重置偏移量到5秒前
        consumer.seek(record.topic(), record.partition(), record.offset() - 1);
    }
}

# 关键配置
spring.kafka.consumer.enable-auto-commit=false
spring.kafka.listener.ack-mode=MANUAL_IMMEDIATE
spring.kafka.consumer.isolation.level=read_committed
