autonumber
Client -> ReconcileService: 发起对账请求

group 1. 创建对账订单
    autonumber 1
    ReconcileService -> ReconcileStrategyFactory: 构建对账策略
    ReconcileService <- ReconcileStrategyFactory: 返回对账策略对象
    ReconcileService -> ReconcileStrategy: 生成批次号
    ReconcileService <- ReconcileStrategy: 返回批次号
    ReconcileService -> ReconcileService: 创建对账订单
    ReconcileService -> ReconcileOrderManager: 保存对账订单
    ReconcileService <- ReconcileOrderManager: 返回对账订单
end

group 2. 下载对账单并进行保存
    autonumber 1
    ReconcileService -> ReconcileStrategyFactory: 构建对账策略
    ReconcileService <- ReconcileStrategyFactory: 返回对账策略对象
    ReconcileService -> ReconcileStrategy: 下载对账单, 并进行解析进行保存
    ReconcileStrategy -> AliPayReconcileService: 发起对账单下载请求，获取对账单下载地址
    AliPayReconcileService -> AliGateway: 发起对账单下载请求，获取对账单下载地址
    AliPayReconcileService <- AliGateway: 返回对账单下载地址
    AliPayReconcileService -> AliGateway: 下载对账单
    AliPayReconcileService <- AliGateway: 返回对账单内容
    AliPayReconcileService -> AliPayReconcileService: 解析对账单, 同时生成通用对账单记录
    AliPayReconcileService --> ReconcileContext: 将解析后的通用对账单记录放到到上下文
    ReconcileStrategy <- AliPayReconcileService: 处理结束
    ReconcileService <- ReconcileStrategy: 处理结束
    ReconcileService <- ReconcileContext: 获取通用对账单记录
    ReconcileService --> reconcileDetailManager: 保存明细记录
end

group 3. 对账单比对
    autonumber 1
    ReconcileService -> ReconcileStrategyFactory: 构建对账策略
    ReconcileService <- ReconcileStrategyFactory: 返回对账策略对象
    ReconcileService <--> ReconcileStrategy: 初始对账策略类
    ReconcileService <- ReconcileStrategy: 获取本地和网关订单数据
    ReconcileService -> ReconcileService: 比对本地和网关订单差异
    ReconcileService --> ReconcileDiffService: 保存差异记录

end
autonumber 2
Client <- ReconcileService: 返回对账结束
