세 번째 테이블이있는 두 개의 테이블 매핑 Fluent Nhibernate

Question

저는 Nhibernate에서 작업 중이며 매핑 (CustomerMap 및 CustomerRoleMap)과 함께 Customer 및 CusotmerRole이라는 두 개의 클래스 이름을 사용합니다. 이제이 두 테이블을 As Customer_CustomerRole_Mapping이라는 데이터베이스에있는 세 번째 테이블과 매핑하려고합니다. 테이블 Customer_CustomerRole_Mapping에는 데이터베이스에 Customer_Id라는 두 개의 열이 있습니다 (기본 키뿐만 아니라 Customer 테이블의 ForeignKey와 CustomerRole_Id 또한 CustomerKey와 ForeignKey가있는 CustomerRole_Id입니다.) 그래서 고객과 Customer_CustomerRole_Mapping을 어떻게 매핑 할 수 있는지 알고 싶습니다 . 그리고 CustomerRole 또한 나는이 또 다른지도를 만들 필요가 있음을 요청해야 또는 나는이 기존의 클래스를 매핑 할 수 있습니다 감사합니다 사전에

Answer 1

만 ". Customer_CustomerRole_Mapping"두 FK의 테이블이있는 경우, 당신은 ~ 별도로 필요하지 않습니다 이 테이블에 대한 매핑.

"Customer_CustomerRole_Mapping." 자체 SurrogateKey 또는 두 개의 FK 이외의 다른 컬럼을 가지고 있다면 ... 매핑 (그리고이 매핑을위한 poco/pojo 클래스)이 필요합니다.

고객 매핑

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

CustRole 매핑

 /* 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() 
      ; 

당신은 내가 CustRole 매핑에서 "MyCustomers"를 부르는 CustomerRole의 POCO/POJO에 고객의 ICollection이 필요합니다.
