/**
|
||||
* 拉卡拉订单分账信息对象
|
||||
* <p>
|
||||
* 分账计算逻辑说明：
|
||||
* 前提条件：分账总金额必须大于0，配送费不能小于0；拉卡拉、商户、平台分账比例必须大于0，
|
||||
* 一级、二级代理商分账比例可以为null或小于等于0
|
||||
* 分账计算支持两种模式：
|
||||
* 1. 基于可分账金额模式（默认）：先扣除拉卡拉手续费和配送费，再对剩余金额进行分账
|
||||
* 2. 基于总金额模式：基于总分账金额进行分账计算
|
||||
* <p>
|
||||
* 分账计算步骤：
|
||||
* 1. 计算拉卡拉分账金额 = 分账总金额 × 拉卡拉分账比例（结果向上取整）
|
||||
* 2. 计算可分账金额 = 分账总金额 - 配送费 - 拉卡拉分账金额
|
||||
* 3. 调整分账比例，确保商户、平台、一级代理商、二级代理商的有效比例之和等于1.0
|
||||
* - 如果有二级代理商参与分账，则调整二级代理商比例
|
||||
* - 否则如果有一级代理商参与分账，则调整一级代理商比例
|
||||
* - 否则调整平台比例
|
||||
* 4. 按优先级计算各参与方分账金额（结果四舍五入）：
|
||||
* - 商户分账金额 = 可分账金额 × 商户分账比例
|
||||
* - 平台分账金额 = 可分账金额 × 平台分账比例
|
||||
* - 一级代理商分账金额 = 可分账金额 × 一级代理商分账比例（如果参与分账）
|
||||
* - 二级代理商分账金额 = 可分账金额 × 二级代理商分账比例（如果参与分账）
|
||||
* 5. 如分配总额与可分账金额不符，则调整最后一个分账方（按优先级顺序）以确保总额平衡：
|
||||
* - 优先调整二级代理商（如果参与分账）
|
||||
* - 否则调整一级代理商（如果参与分账）
|
||||
* - 否则调整平台
|
||||
* - 最后调整商户
|
||||
* 6. 保障各参与方分账比例不能低于指定属性的比例（按优先级处理）：
|
||||
* - 商户优先级最高
|
||||
* - 平台优先级次之
|
||||
* - 一级代理商优先级再次之
|
||||
* - 二级代理商优先级最低
|
||||
* 分账优先级顺序：拉卡拉 > 平台 > 一级代理商 > 二级代理商 > 商户
|
||||
* 商户作为最后分账方，其金额为剩余金额，不强制遵循分账比例
