模板方法的应用
前段时间阅读Edison Zhou写的文章：https://www.cnblogs.com/edisonchou/p/7260758.html;
于是想到自己的工作中LogicHandler中的OrderLogicHandler逻辑处理类中代码太长，长达1000行，不方便阅读；主要是因为针对增员减员订单分开处理，单处理的流程都是一样的，只是各自的内容不一样，所以为了阅读代码便利，进行代码重整，采用模板方法模式对此进行了整理。
处理流程是：验证申报的人员资料----》得到符合要求的订单----》生成订单----》保存。
/// <summary> /// 商保申报减员 /// </summary> /// <param name="orderDto"></param> /// <param name="successList"></param> /// <param name="failList"></param> /// <returns></returns> public object SaveCutInsurance(OrderCutApiDto orderDto, out List<string> successList, out Dictionary<string, string> failList) { successList = new List<string>(); failList = new Dictionary<string, string>(); OrderApiHelper<OrderCutApiDto> orderApiHelper = new OrderApiCutHelper(_orderDetailRep, _policyRep, _publicLogic, _mapper, _packageRep, _v_CustomerInfoRep);//模板类具体使用 orderApiHelper.ValidApply(orderDto, out successList, out failList); if (successList.Count() > 0) { OrderEntity order = orderApiHelper.GetOrder(orderDto, successList); _orderRep.Save(order); } return new { Success = successList, Fail = failList }; } /// <summary> /// 商保申报新增 /// </summary> /// <param name="orderDto"></param> /// <param name="successList"></param> /// <param name="failList"></param> /// <param name="msg">返回的验证信息</param> /// <returns></returns> public object SaveAddInsurance(OrderAddApiDto orderDto, out List<string> successList, out Dictionary<string, string> failList) { successList = new List<string>(); failList = new Dictionary<string, string>(); OrderApiHelper<OrderAddApiDto> orderApiHelper = new OrderApiAddHelper(_orderDetailRep,_policyRep,_publicLogic,_mapper,_packageRep,_v_CustomerInfoRep);//模板类具体使用 orderApiHelper.ValidApply(orderDto,out successList,out failList); if (successList.Count() > 0) { OrderEntity order = orderApiHelper.GetOrder(orderDto, successList); _orderRep.Save(order); } return new { Success = successList, Fail = failList }; }
模板类：OrderApiHelper，继承的子类中都会用到的共同方法可以写在父类中，且要声明类型为protected，这样子类OrderApiCutHelper中可以在重写的方法中直接调用。如HasPackage(),IsIninsurance()等方法
1 public abstract class OrderApiHelper<T> 2 { 3 protected IQueryable<V_CustomerInfo> customerList; 4 protected IPackageRepository _packageRep; 5 protected IV_CustomerInfoRepository _v_CustomerInfoRep; 6 protected IOrderDetailRepository _orderDetailRep; 7 protected IPublicLogicHandler _publicLogic; 8 protected IPolicyRepository _policyRep; 9 protected IMapper _mapper; 10 public OrderApiHelper(IOrderDetailRepository orderDetailRep, IPolicyRepository policyRep, IPublicLogicHandler publicLogic, IMapper mapper, IPackageRepository packageRep, IV_CustomerInfoRepository v_CustomerInfoRep) 11 { 12 _v_CustomerInfoRep = v_CustomerInfoRep; 13 _packageRep = packageRep; 14 _orderDetailRep = orderDetailRep; 15 _mapper = mapper; 16 _publicLogic = publicLogic; 17 _policyRep = policyRep; 18 customerList = _v_CustomerInfoRep.Entities; 19 } 20 21 /// <summary> 22 /// 商保申报验证 23 /// </summary> 24 /// <param name="orderdetail"></param> 25 /// <param name="customerId"></param> 26 /// <param name="success"></param> 27 /// <param name="fail"></param> 28 /// <returns></returns> 29 public abstract void ValidApply(T orderDto,out List<string> successList,out Dictionary<string, string> failList); 30 31 public abstract OrderEntity GetOrder(T orderDto, List<string> successList); 32 33 /// <summary> 34 /// 验证套餐是否存在或上架 35 /// </summary> 36 /// <param name="packageNumber"></param> 37 /// <returns></returns> 38 protected bool HasPackage(string packageNumber) 39 { 40 return _packageRep.Entities.Any(p => p.SerialNumber == packageNumber && p.State == true && p.PackageRefEntities.Count > 0); 41 } 42 43 /// <summary> 44 /// 判断此人是否在保 45 /// </summary> 46 /// <param name="orderdetail"></param> 47 /// <returns></returns> 48 protected bool IsIninsurance(string idCard, string packageNumber) 49 { 50 51 var queryadd = _orderDetailRep.Entities.Where(o => o.IdCard == idCard 52 && o.PackageNumber == packageNumber 53 && o.OperationType == OperationTypeEnum.增员.ToString() 54 && o.Status == OrderDetailStatusEnum.反馈成功.ToString() 55 ); 56 57 var querycut = _orderDetailRep.Entities.Where(o => o.IdCard == idCard 58 && o.PackageNumber == packageNumber 59 && o.OperationType == OperationTypeEnum.减员.ToString() 60 && o.Status == OrderDetailStatusEnum.反馈成功.ToString() 61 ); 62 63 if (queryadd.Count() > querycut.Count()) 64 return true; 65 else 66 return false; 67 } 68 69 /// <summary> 70 /// 判断生效时间内存不存在保单 71 /// </summary> 72 /// <param name="orderdetail"></param> 73 /// <returns></returns> 74 protected bool HasPolicy(string packageNumber, DateTime effectiveTime) 75 { 76 var query = _packageRep.Get(p => p.SerialNumber == packageNumber).PackageRefEntities? 77 .Where(r => 78 r.ProductEntity.PolicyRefEntities.Count() > 0 79 && r.ProductEntity.PolicyRefEntities?.Where(p => 80 p.PolicyEntity.StartTime <= effectiveTime 81 && p.PolicyEntity.EndTime > effectiveTime).Count() > 0); 82 if (query.Count() > 0) 83 return true; 84 else 85 return false; 86 } 87 }
具体子类：OrderApiCutHelper，OrderApiAddHelper继承OrderApiHelper重写各自的验证和生成订单方法。
1 public class OrderApiCutHelper : OrderApiHelper<OrderCutApiDto> 2 { 3 4 public OrderApiCutHelper(IOrderDetailRepository orderDetailRep, IPolicyRepository policyRep, IPublicLogicHandler publicLogic, IMapper mapper, IPackageRepository packageRep, IV_CustomerInfoRepository v_CustomerInfoRep) : base(orderDetailRep, policyRep, publicLogic, mapper, packageRep, v_CustomerInfoRep) 5 { 6 } 7 8 public override OrderEntity GetOrder(OrderCutApiDto orderDto, List<string> successList) 9 { 10 } 11 12 /// <summary> 13 /// 商保申报减员 14 /// </summary> 15 /// <param name="orderDto"></param> 16 /// <param name="successList"></param> 17 /// <param name="failList"></param> 18 /// <returns></returns> 19 public override void ValidApply(OrderCutApiDto orderDto, out List<string> successList, out Dictionary<string, string> failList) 20 { 21 } 22 } 23 24 //OrderApiAddHelper类同上一样
