#消息监听  这里注意 containerFactory = "kafkaOneContainerFactory"  监听哪个数据源 就写哪个kafka配置的方法

@KafkaListener(topics = "${spring.kafka.topic.itemcore.spu}",containerFactory = "kafkaOneContainerFactory")
public void processItemcenterSpuMessage(String spuId) {
    log.warn("process spuId ={}", spuId);
    try {
        long id = Long.valueOf(spuId);
        spuService.createOrUpdateDocuments(id);
    } catch (Exception e) {
        log.error("process spu kafka message fail , message={}", spuId);
    }
}
