specify the keycolumns manually

public class ProductMap : ClassMap<Product>
{
    public ProductMap()
    {
        Id(x => x.Id);
        Map(x => x.ImageUrl);
        HasManyToMany(x => x.ManyProduct)
            .ParentKeyColumn("product1_id")
            .ChildKeyColumn("product2_id")
            .Cascade.All()
            .Table("ProductInProduct");
    }
}
