|
|
// 单位换算服务层
|
|||
|
|
//
|
|||
|
|
// 职责：
|
|||
|
|
// 1. GetConversionFactor - 获取单位换算系数
|
|||
|
|
// 查询UnitConversion表，返回fromUnit→toUnit的换算系数
|
|||
|
|
//
|
|||
|
|
// 2. ConvertWithCeil - 向上取整换算（用于容量计算）
|
|||
|
|
// 公式：ceil(fromQty / factor)
|
|||
|
|
// 示例：50瓶 ÷ 20（瓶/箱）= 2.5 → ceil = 3箱
|
|||
|
|
//
|
|||
|
|
// 3. ConvertExact - 精确换算（用于出入库数量计算）
|
|||
|
|
// 公式：fromQty / factor
|
|||
|
|
// 示例：50瓶 ÷ 20（瓶/箱）= 2.5箱
|
|||
|
|
//
|
|||
|
|
// 核心逻辑：
|
|||
|
|
// - 从UnitConversion表查询换算系数
|
|||
|
|
// - 向上取整确保不满一个单位也占用空间
|
|||
|
|
// - 只能在同一CapacityUnitType（枚举类型）内换算
