问题，在多对多关系

我得类产品和商店具有多对多关系删除操作问题，在多对多关系

我想店里的删除不会导致删除相关产品的而且产品没有的删除的导致相关商店的删除。

由于外键约束，当前正在删除实体引起的异常。

下面是这个类及其流利的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(); 
    } 
}
