問題，在多對多關係

我得類產品和商店具有多對多關係刪除操作問題，在多對多關係

我想店裏的刪除不會導致刪除相關產品的而且產品沒有的刪除的導致相關商店的刪除。

由於外鍵約束，當前正在刪除實體引起的異常。

下面是這個類及其流利的Hibernate映射：

public class Product 
{ 
    public Product() 
    { 
     this.StoresStockedIn = new List<Store>(); 
    } 


    public virtual string Name { get; set; } 

    public virtual double Price { get; set; } 

    public virtual long ProductID { get; set; } 

    public virtual IList<Store> StoresStockedIn { get; set; } 

} 

public class Store 
{ 
    public Store() 
    { 
     this.Products = new List<Product>(); 
     this.Staff = new List<Employee>(); 

    } 

    public virtual string Name { get; set; } 
    public virtual IList<Product> Products { get; set; } 
    public virtual IList<Employee> Staff { get; set; } 
    public virtual long StoreID { get; set; } 
} 

public class ProductMap : ClassMap<Product> 
{ 
    public ProductMap() 
    { 
     this.Id(x => x.ProductID); 
     this.Map(x => x.Name); 
     this.Map(x => x.Price); 
     this.HasManyToMany(x => x.StoresStockedIn) 
      .Cascade.None() 
      .Table("StoreProduct"); 
    } 
public class StoreMap : ClassMap<Store> 
{ 
    public StoreMap() 
    { 
     this.Id(x => x.StoreID); 
     this.Map(x => x.Name); 
     this.HasManyToMany(x => x.Products) 
      .Cascade.None() 
      .Inverse() 
      .Table("StoreProduct"); 
     this.HasMany(x => x.Staff) 
      .Cascade.All() 
      .Inverse(); 
    } 
}
