NHibernate composite-id联合主键配置

1 复合主键主键字段都不容许为null，如果有一个为null的话那么整个对象就是null

2 复合主键类需要重新一些方法

复合主键类如下

[Serializable]
    public class DoorinfoCompositeID
    {

        public virtual string DoorID { get; set; }

public virtual string AICID { get; set; }

        public override bool Equals(object obj)
        {
            return base.Equals(obj);
        }

        public override int GetHashCode()
        {
            return base.GetHashCode();
        }
    }

主体类如下

    public class AICDoorinfo
    {

        public virtual GisBuildAICDoorinfoCompositeID ID
        {
            get;
            set;
        }
        //单元名称
        public virtual string UnitNoName { get; set; }

    }

主体类的映射文件配置如下

  <composite-id name="ID" class="Model.Entities.GisBuildAICDoorinfoCompositeID,Model">
   <key-property name="DoorID" column="DoorID" type="string" ></key-property>
   <key-property name="AICID" column="AICID" type="string" ></key-property>
  </composite-id>
  <property name="UnitNoName" column="UnitNoName" type="string" />
</class>

还有更为简洁方式如：

<composite-id>
   <key-property name="DoorID" column="DoorID" type="int"></key-property>
   <key-property name="AICID" column="AICID" type="int"></key-property>
  </composite-id>
