本文介绍了一个用于查询商品库存信息的方法，该方法通过传入商品ID列表来获取对应的商品库存详情。此外，还提供了一个MyBatis SQL映射文件示例，展示了如何使用foreach标签进行IN条件查询。

public ServiceMessage<List<Map<String, Object>>> queryGoodsStockInfo(List<Long> goodsIds) {
        try {
            if (goodsIds == null || goodsIds.size() < 1) {
                return super.returnParamsError("查询仓库信息参数为空goodsIds");
            }
            List<Map<String, Object>> goodsList = goodsMapper.loadGoodsStock(goodsIds);
            return super.returnCorrectResult(goodsList);
        } catch (Throwable e) {
            return super.returnException(e);
        }
    }

    public List<Map<String, Object>> loadGoodsStock(List<Long> goodsIds);

 <!-- 查询商品仓库信息 -->
    <select id="loadGoodsStock" resultType="HashMap" parameterType="list">
        select  g.goods_id,
                g.stock_id,
                s.STOCK_NO,
                s.STOCK_NAME,
                g.goods_seller
        from 
        goods g , stock s
        where g.STOCK_ID = s.STOCK_ID and
         g.goods_id  in  
         <foreach collection="list" item="listItem" index="index" open="("
            separator="," close=")">
            #{listItem}
        </foreach>
