库之间的调用方法 - 库模式 [英] Call methods between repositories - Repository Pattern

问题描述

我使用存储库模式（如在 http://www.asp.net/mvc 网站的例子）在ASP.NET MVC应用程序。我有两个仓库，一个叫CategoryRepository的另一种叫ProductRepository。我也用两个服务的CategoryService和ProductService验证和调用库方法。我需要在ProductService类别清单，返回一个是在CategoryRepository已实现的方法。我的问题是，这是调用，在CategoryRepository存在从ProductService的ListCategories方法的正确方法是什么？我不想要实现在ProductRepository（DRY哲学）另一种方法ListCategories。谢谢你。

I'm using the Repository Pattern (like the examples in the http://www.asp.net/mvc site) in a ASP.NET MVC application. I have two repositories, one called CategoryRepository an other called ProductRepository. I also use two services, the CategoryService and ProductService to validate and call the repositories methods. I need a list of categories in ProductService, a method that return one is already implemented in the CategoryRepository. My question is, which is the correct way to call the ListCategories method that exists in CategoryRepository from ProductService? I don't want to implement another ListCategories method in the ProductRepository (DRY philosophy). Thanks.

推荐答案

我会推荐滚动类似仓库为一体的服务。因此，如果你创建一个电子商务应用卷起ProductRepository，CategoryRepository等成类似CatalogService的，并将它承载相关的所有信息库。

I would recommend rolling similar repositories into one service. So if you're creating an e-Commerce application roll up ProductRepository, CategoryRepository etc into something like CatalogService and have it host all repositories that are related.
