單據自動轉換並審覈的方法示例

需求要點：在單據A的界面點擊「自動轉換」，則自動產生審覈態的單據B；若單據B不知足審覈條件，則維持「提交」態；若單據B不知足保存校驗，則維持「暫存」態；若轉換失敗，給出界面提示。

實現思路：
1.經過轉換規則來定義單據A到單據B的轉換關係，便於擴展，也便於使用已有的插件和服務；
2.定義一個空操做「自動轉換」，擴展AbstractOperationServicePlugIn，重寫EndOperationTransaction方法，方便處理事務；
3.依次調用單據轉換服務、暫存服務、保存服務、提交服務和審覈服務，以保證當前服務失敗時能維持前一服務的狀態;
4.根據上述服務調用的結果構造「自動轉換」的操做結果；
5.若需求變動，只能生成審覈態的單據B，不然不予生成，就要調用刪除服務將全部審覈不經過的單據刪除，再構造操做結果；也能夠直接拋出異常throw new KDBusinessException("", string.Join("\n", innerResult.ValidationErrors.Select(o => o.Message)))。

    {
    base.EndOperationTransaction(e);
