流利的NHibernate：映射具有不同名稱的列

Question

假設我有一張桌子：

Project
Id
Title
ProjectManagerId
ContactId

ProjectManagerId和ContactId都是來自名為Person的表的ID：

Person
PersonId
Firstname
Lastname

如何映射這兩列以創建人員對象？ （使用自動映射或fluent的法線貼圖）。

謝謝

Answer 1

只需創建兩個類即可：

public class Person
{
    public virtual int PersonId { get; set; }

    public virtual string FirstName { get; set; }

    public virtual string Surname { get; set; }
}


public class Project
{
    public virtual int ProjectId { get; set; }

    public virtual string Title { get; set; }

    public virtual Person ProjectManager { get; set; }

    public virtual Person Contact { get; set; }
}

和Project的映射類，因為它比Person更有趣：)

public class ProjectMap : ClassMap<Project>
{
    public ProjectMap()
    {
        Id(x => x.ProjectId);
        Map(x => x.Title);
        References(x => x.ProjectManager);
        References(x => x.Contact);
    }
}

如果您正在使用FNH

映射覆蓋將類似於：

public class ProjectMappingOverride : IAutoMappingOverride<Project>
{
    public void Override(AutoMapping<Project> mapping)
    {
        mapping.Id(x => x.ProjectId); //Usually for Id I have a convention, and not define it here
        mapping.Map(x => x.Title); //Also for simple properties. You could remove these lines if you have setup the conventions.
        mapping.References(x => x.ProjectManager);
        mapping.References(x => x.Contact);
    }
}

不要忘記約定其他配置:)

好吧，我要做的就是創建一個名為“ Person”的視圖，其中包含所需的數據，然后將其映射，就像普通表一樣。
