比如秒杀网关业务场景
@Component
public class SecKillProductConfig implements InitializingBean {    private static final Map<String, SecKillProductDobj> PRODUCT_CONFIG_MAP =
        new ConcurrentHashMap<>(16);    @PostConstruct
    public void init() {
        List<SecKillProductDobj> killProductList = secKillProductService.querySecKillProductList();
        if (killProductList == null) {
            throw new RuntimeException("请确保数据库中存在秒杀商品配置!");
        }
        killProductList.stream().forEach((secKillProductDobj -> {
            String prodId = secKillProductDobj.getProdId();
            PRODUCT_CONFIG_MAP.put(prodId, secKillProductDobj);
        }));
        LOGGER.info("[SecKillProductConfig]初始化秒杀配置完成,商品信息=[{}]", JSON.toJSONString(PRODUCT_CONFIG_MAP));
    }这里的ConcurrentHashMap能不能换成HashMap?
