EF 核心中的持久性数据层，动态 EF.将 EF 与模型分开 [英] Persistance datalayer in EF core ,dynamic EF. Separate EF from models

问题描述

我想将 EF 层从我的模型中分离出来.

I want to separate EF layer from my model .

我需要一个 EF Builder 来像这样将我的模型发送给它(我找到了 mongodb 的这段代码，但我需要 EF 核心):

I need a EF Builder to send my model to it like this(I found this code for mongodb but i need for EF core) :

        builder.AddMongo();
        builder.AddMongoRepository<Cart>("Carts");
        builder.AddMongoRepository<Customer>("Customers");
        builder.AddMongoRepository<Product>("Products");

以上代码在启动文件中.

The above code is inside startup file .

我从 applicationsetting.json 文件中传递参数，如您所见:

I pass the parameters from applicationsetting.json file as you can see :

 "mongo": {
    "connectionString": "mongodb://localhost:27017",
    "database": "customers-service",
    "seed": false
  },

这是mongo示例代码:

Here is the mongo sample code :

public static class Extensions
    {
        public static void AddMongo(this ContainerBuilder builder)
        {
            builder.Register(context =>
            {
                var configuration = context.Resolve<IConfiguration>();
                var options = configuration.GetOptions<MongoDbOptions>("mongo");

                return options;
            }).SingleInstance();

            builder.Register(context =>
            {
                var options = context.Resolve<MongoDbOptions>();

                return new MongoClient(options.ConnectionString);
            }).SingleInstance();

            builder.Register(context =>
            {
                var options = context.Resolve<MongoDbOptions>();
                var client = context.Resolve<MongoClient>();
                return client.GetDatabase(options.Database);

            }).InstancePerLifetimeScope();

            builder.RegisterType<EFDbInitializer>()
                .As<IEFDbInitializer>()
                .InstancePerLifetimeScope();

            builder.RegisterType<MongoDbSeeder>()
                .As<IEFDbSeeder>()
                .InstancePerLifetimeScope();
        }

        public static void AddMongoRepository<TEntity>(this ContainerBuilder builder, string collectionName)
            where TEntity : IIdentifiable
            => builder.Register(ctx => new EFRepository<TEntity>(ctx.Resolve<IMongoDatabase>(), collectionName))
                .As<IMongoRepository<TEntity>>()
                .InstancePerLifetimeScope();
    }

我的问题是:有没有像 mongo 这样的 EF 的解决方案?

My question is :is there any solution for EF like mongo ?

mongoDb 的每一部分代码都可用.

Every part of code for mongoDb is available.

推荐答案

首先，我相信有一点困惑:

First of all, I believe there is a little confusion :

• MongoDB 是一个数据库
• Entity Core 是一个 ORM.它允许您访问存储中的数据

• MongoDB is a database
• Entity Core is an ORM. It allows you to access to data in a storage

也就是说，您可以将 EF Core 与多个数据存储一起使用，例如 MongoDB 或 SQL Server.

That said, you can use EF Core with several data storages, such as MongoDB or SQL Server for instance.

希望实体(数据访问层)和业务模型之间有一个分离层是一种很好的做法，应该鼓励.

由于主题广泛，并且存在大量文档和教程以及主题，因此我更愿意给您一些链接，而不是给您一个完整的架构.

To want a separated layer between your entities (Data Access Layer) and your business model is a good practice, and should be encouraged.

Because the topic is wide, and because lot of documentations and tutorials exists and the subject, I prefer to give you some links rather than to give you a complete architecture.

您可以查看此文档 来自 Microsoft，以查看相关层以及它们应包含的内容.

You can check this documentation from Microsoft to see the related layers, and what they should contains.

另外，我建议你参考 这个 github repo，它提供了大量基于.net 核心.

Also, I advise you to consult this github repo, which provide tons of clean architectures based on .net core.

随意挖掘这些链接，它们提供了很多宝贵的信息.

Feel free to dig a bit into those links, they are providing a lot of precious informations.

希望有帮助.
