将两个表映射到第三个表Fluent Nhibernate

我正在研究Nhibernate，我有两个类，分别是Customer和CusotmerRole及其映射（CustomerMap和CustomerRoleMap）。现在我想将这两个表映射到数据库中名为Customer\u CustomerRole\u Mapping的第三个表。表Customer\u CustomerRole\u映射在数据库中有两列，一列是Customer\u Id（主键和ForeignKey与Customer表一起，另一个是CustomerRole\u Id，它也是CustomerRole表的主键和外键。因此我想知道如何将Customer\u CustomerRole\u映射与Customer和CustomerRole映射。我还需要要求为此创建另一个映射，或者我可以映射这些现有的类。提前谢谢

        /* the below is how to do it without a surogatekey on the link table */
        HasManyToMany<CustomerNHEntity>(x => x.MyCustomers) /* I think this is missing on the POCO */
       .Table("Customer_CustomerRole_Mapping")
            .ParentKeyColumns.Add("AbcCustRoleUUID", p => p.UniqueKey("Emp_CustRole_Unique").Index("IX_ABC123"))
            .ChildKeyColumns.Add("AbcCustomerUUID", p => p.UniqueKey("Emp_CustRole_Unique"))
            .Cascade.None()
            ;
