流利的NHibernate的主鍵之一也是外鍵 - OutOfRangeException

Question

Cart 
{ 
CompositeId().KeyProperty(x => x.CART_ID, "CART_ID").KeyProperty(x => x.COMM_CD, "COMM_CD"); 
References(x => x.Product, "COMM_CD"); 
} 

當我試圖將車對象保存到數據庫我收到超出範圍的異常。我認爲這是因爲我有兩個COMM_CD屬性。有沒有辦法解決這個問題？

感謝

您需要使用KeyReference代替KeyProperty

CompositeId() 
    .KeyProperty(x => x.CART_ID, "CART_ID") 
    .KeyReference(x => x.Product, "COMM_CD");
