流利的Nhibernate：自指多对多

使用此类和映射：

Public class Something
{
    public int Id;
    public IList<Something> Similarthings { get; set; }
}

public class SomtehingMapping
    {
        public SomtehingMapping()
        {
            Map(x => x.Id);
            HasManyToMany(x => x.Similarthings )
               .Table("SomethingsToSimilarthings")
               .ParentKeyColumn("SomethingA_Id")
               .ChildKeyColumn("SomethingB_Id")
               .Cascade.All();
         }
}

有没有办法定义此映射，以便只使用一个数据库行来表示双向关系？

您是否尝试过像这样将反向映射属性设置为真

public class SomtehingMapping
    {
        public SomtehingMapping()
        {
            Map(x => x.Id);
            HasManyToMany(x => x.Similarthings )
               .Inverse()
               .Table("SomethingsToSimilarthings")
               .ParentKeyColumn("SomethingA_Id")
               .ChildKeyColumn("SomethingB_Id")
               .Cascade.All();
         }
}

另一种方法是明确定义关联的另一端，并将其标记为

inverse=“true”

尚未尝试过。很难想象在这种情况下，Inverse=true意味着什么。我试试看，然后回来。

public class SomtehingMapping
    {
        public SomtehingMapping()
        {
            Map(x => x.Id);
            HasManyToMany(x => x.Similarthings )
               .Inverse()
               .Table("SomethingsToSimilarthings")
               .ParentKeyColumn("SomethingA_Id")
               .ChildKeyColumn("SomethingB_Id")
               .Cascade.All();
         }
}
