c# - 如何使用 FK NHibernate 映射复合 PK

Question

我想映射这样的东西:

表 FOO:复合 PK:ID_OTHERFOOFK1 (PFK)、ID_OTHERFOOFK2 (PFK)、ID_FOO (PK)

表OTHERFOO1关系:OTHERFOO1一对多FOO表OTHERFOO2关系:OTHERFOO2一对多FOO

类(class)会是什么样子？hbm.xml 会是什么样子？

Answer 1

class Foo
{
    public virtual int Id { get; set; }
    public virtual Foo1 Foo1 { get; set; }
    public virtual Foo2 Foo2 { get; set; }
}

class Foo1
{
    public virtual int Id { get; set; }
}

class Foo2
{
    public virtual int Id { get; set; }
}

<composite-id>
  <key-property name="id" column="ID_FOO"/>
  <key-many-to-one name="Foo1" column="ID_OTHERFOOFK1"/>
  <key-many-to-one name="Foo2" column="ID_OTHERFOOFK2"/>
</composite-id>
