Nhibernate一对多级联保存双向映射.docVIP

一对多关系示例，Base_Order和Base_OrderDetail是一对多的关系，通过Base_Order.OrderId和Base_OrderDetail.OrderId关联： 实体Order代码： [Class(Table = BASE_Order)] public class Order : Common.BaseEntity { private IList _childList; public Order() { _childList = new ArrayList(); } /// summary /// 主键 /// /summary [Id(0, Name = OrderId, Column = OrderId, TypeType = typeof(int),UnsavedValue=0)] [Generator(1, Class = native)] public virtual int? OrderId { get; set; } /// summary /// 订单编号 /// /summary [Property(Name = OrderCode, Column = OrderCode, TypeType = typeof(String), Length = 128)] public virtual string OrderCode { get; set; } //订单明细物料，返回一个ArrayList对象 [Bag(0, Cascade = all, Name = Cascade_OrderDetail,Inverse=true,Lazy=CollectionLazy.False)] [Key(1,Column=OrderId)] [OneToMany(1, ClassType = typeof(OrderDetail))] public virtual IList Cascade_OrderDetail { get{ return _childList; } set{ this._childList = value; } } } 注意： OrderDetail类中的 [KeyManyToOne(1, Column = OrderId)]声明，是对应Order类中的[Key(1,Column=OrderId)]声明，这两个属性必须成对出现，否则Nhibernate.Mapping.Attributes生成的xml会缺key属性 Nhibernate.Mapping.Attributes对应生成的Xml文件： class table=BASE_Order name=Basal.Organization.Domain.Order, Basal.Organization id name=OrderId column=OrderId type=Int32 unsaved-value=0 generator class=native / /id property name=OrderCode type=String column=OrderCode length=128 / bag name=Cascade_OrderDetail lazy=false inverse=true cascade=all key column=OrderId / one-to-many class=Basal.Organization.Domain.OrderDetail, Basal.Organization / /bag /class 实体OrderDetail代码： [Class(Table = BASE_OrderDetail)] public class OrderDetail : Common.BaseEntity { /// summary /// 主键 /// /summary [Id(0, Name = OrderDetailId, Column = OrderDetailId, TypeType = typeof(int), UnsavedValue = 0)] [Generator(1, Class = native)] public virtual int?
