Dapper and Repository Pattern in MVC

大家好，首先原谅我标题是英文的，因为我想不出好的中文标题。

这里我个人写了一个Dapper.net 的Repository模式的底层基础框架。

涉及内容：

Dapper.net结合Repository的设计，可切换不同数据库及当前操作数据库的事务支持，依赖注入（工具：Autofac）。

项目可直接在此基础框架上开发。

该底层架构分层参考：

Nopcommerce：https://www.nopcommerce.com

 以及自己累积的经验分层及设计

项目结构图：

DapperRepository.Core: 放置相关数据接口和实体类

DapperRepository.Data:数据操作层，实现具体Repository和数据库连接及访问

DapperRepository.Services:业务逻辑层，处理相关业务逻辑

DapperRepository.Web:web端，客户端操作

以下简称Core、Data、Services、Web

数据库脚本：

创建数据库：

USE [master]
GO

/****** Object:  Database [DapperRepositoryDb]    Script Date: 2/28/2019 2:59:41 PM ******/
CREATE DATABASE [DapperRepositoryDb]

创建表和演示数据：

USE [DapperRepositoryDb]
GO

/****** Object:  Table [dbo].[Customer]    Script Date: 2019/2/28 14:54:06 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[Customer](
    [Id] [INT] IDENTITY(1,1) NOT NULL,
    [Username] [NVARCHAR](32) NOT NULL,
    [Email] [NVARCHAR](128) NOT NULL,
    [Active] [BIT] NOT NULL,
    [CreationTime] [DATETIME] NOT NULL,
 CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

/****** Object:  Table [dbo].[CustomerRole]    Script Date: 2019/2/28 14:54:26 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[CustomerRole](
    [Id] [INT] IDENTITY(1,1) NOT NULL,
    [Name] [NVARCHAR](32) NOT NULL,
    [SystemName] [NVARCHAR](32) NOT NULL,
    [CreationTime] [DATETIME] NOT NULL,
 CONSTRAINT [PK_CustomerRole] PRIMARY KEY CLUSTERED

GO

/****** Object:  Table [dbo].[Customer_CustomerRole_Mapping]    Script Date: 2019/2/28 14:54:40 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[Customer_CustomerRole_Mapping](
    [CustomerId] [INT] NOT NULL,
    [CustomerRoleId] [INT] NOT NULL
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[Customer_CustomerRole_Mapping]  WITH CHECK ADD  CONSTRAINT [FK_Customer_CustomerRole_Mapping_Customer] FOREIGN KEY([CustomerId])
REFERENCES [dbo].[Customer] ([Id])
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[Customer_CustomerRole_Mapping] CHECK CONSTRAINT [FK_Customer_CustomerRole_Mapping_Customer]
GO

ALTER TABLE [dbo].[Customer_CustomerRole_Mapping]  WITH CHECK ADD  CONSTRAINT [FK_Customer_CustomerRole_Mapping_CustomerRole] FOREIGN KEY([CustomerRoleId])

ON DELETE CASCADE
GO

ALTER TABLE [dbo].[Customer_CustomerRole_Mapping] CHECK CONSTRAINT [FK_Customer_CustomerRole_Mapping_CustomerRole]
GO


INSERT INTO [dbo].[CustomerRole]
           ([Name]
           ,[SystemName]
           ,[CreationTime])
     VALUES
           ('Admin',
           'Admin',
           GETDATE())
GO

INSERT INTO [dbo].[CustomerRole]
           ([Name]
           ,[SystemName]
           ,[CreationTime])
     VALUES
           ('Guest',
           'Guest',
           GETDATE())
GO

创建分页存储过程（分页方案来自：https://www.foxnetsoft.com/nopmssqlprovider，下载Sample即可）

USE [DapperSampleDb];
GO

/****** Object:  StoredProcedure [dbo].[DRD_Customer_GetAllCustomers]    Script Date: 3/3/2019 1:23:45 PM ******/
SET ANSI_NULLS ON;
GO

SET QUOTED_IDENTIFIER ON;
GO

CREATE PROCEDURE [dbo].[DRD_Customer_GetAllCustomers]
    (
      @PageIndex INT ,
      @PageSize INT ,
      @TotalRecords INT OUTPUT
    )
AS
    BEGIN
        SET NOCOUNT ON;

        -- paging
        DECLARE @PageLowerBound INT;
        DECLARE @PageUpperBound INT;
        DECLARE @RowsToReturn INT;
        SET @RowsToReturn = @PageSize * ( @PageIndex + 1 );
        SET @PageLowerBound = @PageSize * @PageIndex;
        SET @PageUpperBound = @PageLowerBound + @PageSize + 1;

        CREATE TABLE #PageIndex
            (
              [IndexId] INT IDENTITY(1, 1)
                            NOT NULL ,
              [CustomerId] INT NOT NULL
            );

        INSERT  INTO #PageIndex
                ( CustomerId
                )
                SELECT  Id
                FROM    dbo.Customer
                ORDER BY Id DESC;

        -- total records
        SET @TotalRecords = @@ROWCOUNT;

        -- return customers
        SELECT TOP ( @RowsToReturn )
                c.Id ,
                c.Username ,
                c.Email ,
                c.Active ,
                c.CreationTime ,
                cr.Id ,
                cr.Name ,
                cr.SystemName
        FROM    #PageIndex [pi]
                INNER JOIN dbo.Customer c ON c.Id = [pi].CustomerId
                INNER JOIN Customer_CustomerRole_Mapping crm ON c.Id = crm.CustomerId
                INNER JOIN CustomerRole cr ON crm.CustomerRoleId = cr.Id
        WHERE   pi.IndexId > @PageLowerBound
                AND pi.IndexId < @PageUpperBound
        ORDER BY pi.IndexId;

        DROP TABLE #PageIndex;

    END;

接下俩详细分析：

实体基类BaseEntity:

namespace DapperRepository.Core
{
    public abstract class BaseEntity
    {
        public int Id { get; set; }
    }
}

Core：

建立一个名为Data的文件夹放置IDbSession和IRepository：

IDbSession:

using System;
using System.Data;

namespace DapperRepository.Core.Data
{
    public interface IDbSession : IDisposable
    {
        IDbConnection Connection { get; }
        IDbTransaction Transaction { get; }

        IDbTransaction BeginTrans(IsolationLevel isolation = IsolationLevel.ReadCommitted);
        void Commit();
        void Rollback();
    }
}

这个接口定义数据数据连接对象属性和事务属性，以及相关事务性的操作方法。

IRepository:

using System.Data;
using System.Collections.Generic;

namespace DapperRepository.Core.Data
{
    public interface IRepository<T> where T : BaseEntity
    {
        /// <summary>
        /// 根据主键获取一条数据
        /// </summary>
        /// <param name="sql">sql语句或者存储过程</param>
        /// <param name="param">语句参数</param>
        /// <param name="buffered">是否缓冲查询数据，详细信息：https://dapper-tutorial.net/buffered </param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="commandType">命令类型（sql语句或是存储过程）</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>当前查询数据</returns>
        T GetById(string sql, object param = null, bool buffered = true, int? commandTimeout = null,
            CommandType? commandType = null, bool useTransaction = false);

        /// <summary>
        /// 根据相关条件获取一条数据
        /// </summary>
        /// <param name="sql">sql语句或者存储过程</param>
        /// <param name="param">语句参数</param>
        /// <param name="buffered">是否缓冲查询数据，详细信息：https://dapper-tutorial.net/buffered </param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="commandType">命令类型（sql语句或是存储过程）</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>当前查询数据</returns>
        T GetBy(string sql, object param = null, bool buffered = true, int? commandTimeout = null,
            CommandType? commandType = null, bool useTransaction = false);

        /// <summary>
        /// 获取数据列表（所有、部分或者分页获取）
        /// </summary>
        /// <param name="sql">sql语句或者存储过程</param>
        /// <param name="param">语句参数</param>
        /// <param name="buffered">是否缓冲查询数据，详细信息：https://dapper-tutorial.net/buffered </param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="commandType">命令类型（sql语句或是存储过程）</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>当前查询数据列表</returns>
        IEnumerable<T> GetList(string sql, object param = null, bool buffered = true, int? commandTimeout = null,
            CommandType? commandType = null, bool useTransaction = false);

        /// <summary>
        /// 添加数据
        /// </summary>
        /// <param name="entity">要添加的实体对象</param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>执行结果（一般为添加的Id）</returns>
        dynamic Insert(T entity, int? commandTimeout = null, bool useTransaction = false);

        /// <summary>
        /// 修改数据
        /// </summary>
        /// <param name="entity">要修改的实体对象</param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>执行结果（true or false）</returns>
        bool Update(T entity, int? commandTimeout = null, bool useTransaction = false);

        /// <summary>
        /// 删除数据
        /// </summary>
        /// <param name="entity">要删除的实体对象</param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>执行结果（true or false）</returns>
        bool Delete(T entity, int? commandTimeout = null, bool useTransaction = false);

        /// <summary>
        /// 执行对象sql语句（一般需要事务处理）
        /// </summary>
        /// <param name="sql">sql语句或者存储过程</param>
        /// <param name="param">语句参数</param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="commandType">命令类型（sql语句或是存储过程）</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>执行受影响的行数</returns>
        int Execute(string sql, object param = null, int? commandTimeout = null, CommandType? commandType = null,
            bool useTransaction = true);
    }
}

这里定义相关数据操作（增删查改）的基础方法。或许有些开发者会问为何分页，执行存储过程的基础方法都没有。这里我个人说明下，因为dapper.net是精简orm，并不像EF那样集成了很多方法和扩展，dapper主要还是依赖于写的sql语句的处理逻辑。所以这里分页的话你写好sql语句或者存储过程并调用GetList方法即可。

创建一个名为Domain的文件夹放置相关实体：

DataBaseType枚举（数据库类型：MSSQL、MYSQL、ORACLE...）

namespace DapperRepository.Core.Domain
{
    public enum DatabaseType
    {
        Mssql,
        Mysql,
        Oracle
    }
}

相关实体：

Customer：

using System;

namespace DapperRepository.Core.Domain.Customers
{
    public class Customer : BaseEntity
    {
        public string Username { get; set; }

        public string Email { get; set; }

        public bool Active { get; set; }

        public DateTime CreationTime { get; set; }
    }
}

CustomerRole:

namespace DapperRepository.Core.Domain.Customers
{
    public class CustomerRole : BaseEntity
    {
        public string Name { get; set; }

        public string SystemName { get; set; }
    }
}

Dto实体CustomerDtoModel：

using System;

namespace DapperRepository.Core.Domain.Customers
{
    public class CustomerDtoModel
    {
        public int Id { get; set; }

        public string Username { get; set; }

        public string Email { get; set; }

        public bool Active { get; set; }

        public DateTime CreationTime { get; set; }

        public virtual CustomerRole CustomerRole { get; set; }
    }
}

Data：

新建一个类ConnConfig用于获取数据连接字符串：

using System.Configuration;
using System.Web.Configuration;

namespace DapperRepository.Data
{
    public class ConnConfig
    {
        private readonly static Configuration Config = WebConfigurationManager.OpenWebConfiguration("~");

        /// <summary>
        /// mssql 连接字符串
        /// </summary>
        private static string _mssqlConnectionString = Config.AppSettings.Settings["MssqlConnectionString"].Value;
        /// <summary>
        /// mysql 连接字符串
        /// </summary>
        private static string _mysqlConnectionString = Config.AppSettings.Settings["MysqlConnectionString"].Value;
        /// <summary>
        /// oracle 连接字符串
        /// </summary>
        private static string _oracleConnectionString = Config.AppSettings.Settings["OracleConnectionString"].Value;

        public static string MssqlConnectionString
        {
            get { return _mssqlConnectionString; }
            set { _mssqlConnectionString = value; }
        }

        public static string MysqlConnectionString
        {
            get { return _mysqlConnectionString; }
            set { _mysqlConnectionString = value; }
        }

        public static string OracleConnectionString
        {
            get { return _oracleConnectionString; }
            set { _oracleConnectionString = value; }
        }
    }
}

工厂类SessionFactory用于切换某个数据库以及创建数据库会话：

using System.Data;
using System.Data.OracleClient;
using System.Data.SqlClient;
using DapperRepository.Core.Data;
using DapperRepository.Core.Domain;
using MySql.Data.MySqlClient;

namespace DapperRepository.Data
{
    public class SessionFactory
    {
        private static IDbConnection CreateConnection(DatabaseType dataType)
        {
            IDbConnection conn;
            switch (dataType)
            {
                case DatabaseType.Mssql:
                    conn = new SqlConnection(ConnConfig.MssqlConnectionString);
                    break;
                case DatabaseType.Mysql:
                    conn = new MySqlConnection(ConnConfig.MysqlConnectionString);
                    break;
                case DatabaseType.Oracle:
                    conn = new OracleConnection(ConnConfig.OracleConnectionString);
                    break;
                default:
                    conn = new SqlConnection(ConnConfig.MssqlConnectionString);
                    break;
            }

            conn.Open();

            return conn;
        }

        /// <summary>
        /// 创建数据库连接会话
        /// </summary>
        /// <returns></returns>
        public static IDbSession CreateSession(DatabaseType databaseType)
        {
            IDbConnection conn = CreateConnection(databaseType);
            IDbSession session = new DbSession(conn);
            return session;
        }
    }
}

IDbSession的实现类DbSession：

using System;
using System.Data;
using DapperRepository.Core.Data;

namespace DapperRepository.Data
{
    public class DbSession : IDbSession
    {
        private IDbConnection _connection;
        private IDbTransaction _transaction;

        public DbSession(IDbConnection conn)
        {
            _connection = conn;
        }

        public IDbConnection Connection
        {
            get { return _connection; }
        }

        public IDbTransaction Transaction
        {
            get { return _transaction; }
        }

        public IDbTransaction BeginTrans(IsolationLevel isolation = IsolationLevel.ReadCommitted)
        {
            _transaction = _connection.BeginTransaction(isolation);

            return _transaction;
        }

        public void Commit()
        {
            _transaction.Commit();
        }

        public void Rollback()
        {
            _transaction.Rollback();
        }

        public void Dispose()
        {
            if (_transaction != null)
            {
                _transaction.Dispose();
                _transaction = null;
            }

            if (_connection != null)
            {
                if (_connection.State == ConnectionState.Open)
                    _connection.Close();

                _connection.Dispose();
                _connection = null;
            }

            GC.SuppressFinalize(this);
        }
    }
}

抽象类RepositoryBase用于实现IRepository接口的方法：

using System;
using System.Linq;
using System.Data;
using System.Collections.Generic;
using Dapper;
using DapperExtensions;
using DapperRepository.Core;
using DapperRepository.Core.Data;
using DapperRepository.Core.Domain;

namespace DapperRepository.Data
{
    public abstract class RepositoryBase<T> where T : BaseEntity
    {
        protected virtual IDbSession DbSession
        {
            get { return SessionFactory.CreateSession(DataType); }
        }

        /// <summary>
        /// 数据库类型（MSSQL,MYSQL...）
        /// </summary>
        protected abstract DatabaseType DataType { get; }

        /// <summary>
        /// 根据主键获取一条数据
        /// </summary>
        /// <param name="sql">sql语句或者存储过程</param>
        /// <param name="param">语句参数</param>
        /// <param name="buffered">是否缓冲查询数据，详细信息：https://dapper-tutorial.net/buffered </param>
        /// <param name="commandTimeout">执行超时时间</param>
        /// <param name="commandType">命令类型（sql语句或是存储过程）</param>
        /// <param name="useTransaction">是否开启事务</param>
        /// <returns>当前查询数据</returns>
        public virtual T GetById(string sql, object param = null, bool buffered = true, int? commandTimeout = null, CommandType? commandType = null, bool useTransaction = false)
        {
            if (string.IsNullOrEmpty(sql))

Services：

接口ICustomerService：

using System.Collections.Generic;
using DapperRepository.Core.Domain.Customers;

        int InsertCustomer(Customer customer, int roleId);

        int UpdateCustomer(Customer customer, int roleId);

        bool DeleteCustomer(Customer customer);
    }
}

对应实现类CustomerService：

using System;
using System.Collections.Generic;
using DapperRepository.Core.Domain.Customers;
using DapperRepository.Data.Repositories.Customers;

namespace DapperRepository.Services.Customers
{
    public class CustomerService : ICustomerService
    {

}

Web：

建立文件夹Infrastructure用于存放依赖注入的配置类Bootstrapper：

using System.Reflection;
using System.Web.Mvc;
using Autofac;
using Autofac.Integration.Mvc;
using DapperRepository.Data.Repositories.Customers;
using DapperRepository.Services.Customers;

namespace DapperRepository.Web.Infrastructure
{
    public class Bootstrapper
    {
        public static void Run()
        {
            SetAutofacContainer();
        }

        private static void SetAutofacContainer()
        {
            ContainerBuilder builder = new ContainerBuilder();

            builder.RegisterControllers(Assembly.GetExecutingAssembly());

            // Repositories
            builder.RegisterType<CustomerRepository>().As<ICustomerRepository>().InstancePerLifetimeScope();
            builder.RegisterType<CustomerRoleRepository>().As<ICustomerRoleRepository>().InstancePerLifetimeScope();

            // Services
            builder.RegisterType<CustomerService>().As<ICustomerService>().InstancePerLifetimeScope();
            builder.RegisterType<CustomerRoleService>().As<ICustomerRoleService>().InstancePerLifetimeScope();

            IContainer container = builder.Build();

            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
        }
    }
}

添加控制器CustomerController：
