商品实体类

/**
 * 商品
 */
@Data
public class Goods {
    @TableId
    private Integer goodsId;
    private String goodsImg;//图片
    private String goodsName;//名称
    private String goodsCaption; // 副标题
    private String goodsPrice;//价格
    private String goodsStock;//库存
    private String goodsSalvesVolume;//销量
    private String goodsType;//商品类型
    private String goodsSpecification;//商品规格
    private String goodsDesc;//简介
    private Boolean goodsMarketable; // 是否上架


}

mapper接口

public interface GoodsMapper extends BaseMapper {
}
