作業単位とリポジトリ フレームワーク |公式URF、追跡可能なエンティティ、デザイン ファクトリー チーム
このフレームワーク (合計 100,000 以上のダウンロード) により、ORM テクノロジーがアプリケーションに拡散する表面積が最小限に抑えられます。このフレームワークは、軽量で設置面積が小さく、拡張や保守が難しくないように意図的に設計されています。軽量と言うとき、実際には軽量を意味します。このフレームワークを Entity Framework プロバイダーで使用する場合、クラスは 10 個しかありません。この軽量フレームワークを使用すると、リポジトリ、作業単位、およびドメイン駆動設計を使用して、アプリケーションとシステムをエレガントに、目立たず、簡単にパターン化できます。汎用リポジトリを使用するかどうか?このフレームワークでは、汎用リポジトリの自由さと、独自のドメイン固有のリポジトリ メソッド、つまり拡張可能な汎用リポジトリを使用した作業単位を追加する機能の両方が可能になります。

ServiceのRepositoryから公開されるすべてのメソッドは、前または後のドメイン/ビジネス ロジックを追加するためにオーバーライドできます。ドメイン ビジネス ロジックは、懸念事項を分離するために、コントローラーやリポジトリではなく、サービス層にある必要があります。
ICustomerServiceを作成します。これは常にIServiceを継承する必要があります (例: IServiceICustomerServiceを実装するCustomerServicecontainer.RegisterType() と IoC の接続の詳細については、次の例を参照してください。 public interface ICustomerService : IService < Customer >
{
decimal CustomerOrderTotalByYear ( string customerId , int year ) ;
IEnumerable < Customer > CustomersByCompany ( string companyName ) ;
IEnumerable < CustomerOrder > GetCustomerOrder ( string country ) ;
}
public class CustomerService : Service < Customer > , ICustomerService
{
private readonly IRepositoryAsync < Customer > _repository ;
public CustomerService ( IRepositoryAsync < Customer > repository ) : base ( repository )
{
_repository = repository ;
}
public decimal CustomerOrderTotalByYear ( string customerId , int year )
{
// add any domain logic here
return _repository . GetCustomerOrderTotalByYear ( customerId , year ) ;
}
public IEnumerable < Customer > CustomersByCompany ( string companyName )
{
// add any domain logic here
return _repository . CustomersByCompany ( companyName ) ;
}
public IEnumerable < CustomerOrder > GetCustomerOrder ( string country )
{
// add any domain logic here
return _repository . GetCustomerOrder ( country ) ;
}
public override void Insert ( Customer entity )
