NetCore+Dapper WebApi架构搭建（二）：底层封装

看下我们上一节搭建的架构，现在开始从事底层的封装

1、首先需要一个实体的接口IEntity

11 namespace Dinner.Dapper
22 {
33     public interface IEntity<TPrimaryKey>
44     {
55         TPrimaryKey Id { get; set; }
66     }
77 }

2、由于所有的数据库实体都是有主键的，所以这里定义一个BaseModel，这里我用的主键是Guid，你们可以换成int

11 using System;
22 
33 namespace Dinner.Dapper
44 {
55     public class BaseModel : IEntity<Guid>
66     {
77         public Guid Id { get; set; }
88     }
99 }

3、接下来是封装Dapper的SqlServer配置DataBaseConfig（Redis的配置你们可以忽略）,不要忘记添加Dapper的Nuget包

1 1 using StackExchange.Redis;
2 2 using System.Data;
3 3 using System.Data.SqlClient;
4 4 
5 5 namespace Dinner.Dapper
6 6 {
7 7     public class DataBaseConfig
8 8     {
9 9         #region SqlServer链接配置
1010 
1111         private static string DefaultSqlConnectionString = @"Data Source=localhost;Initial Catalog=Dinner;User ID=sa;Password=123456;";
1212         private static string DefaultRedisString = "localhost, abortConnect=false";
1313         private static ConnectionMultiplexer redis;
1414 
1515         public static IDbConnection GetSqlConnection(string sqlConnectionString = null)
1616         {
1717             if (string.IsNullOrWhiteSpace(sqlConnectionString))
1818             {
1919                 sqlConnectionString = DefaultSqlConnectionString;
2020             }
2121             IDbConnection conn = new SqlConnection(sqlConnectionString);
2222             conn.Open();
2323             return conn;
2424         }
2525 
2626         #endregion
2727 
2828         #region Redis链接配置
2929 
3030         private static ConnectionMultiplexer GetRedis(string redisString = null)
3131         {
3232             if (string.IsNullOrWhiteSpace(redisString))
3333             {
3434                 redisString = DefaultRedisString;
3535             }
3636             if (redis == null || redis.IsConnected)
3737             {
3838                 redis = ConnectionMultiplexer.Connect(redisString);
3939             }
4040             return redis;
4141         }
4242 
4343         #endregion
4444     }
4545 }

4、然后是仓储基接口IRepositoryBase，添加了基本的增删改查和一个无参的存储过程

1 1 using System;
2 2 using System.Collections.Generic;
3 3 using System.Threading.Tasks;
4 4 
5 5 namespace Dinner.Dapper
6 6 {
7 7     public interface IRepositoryBase<T>
8 8     {
9 9         Task Insert(T entity, string insertSql);
1010 
1111         Task Update(T entity, string updateSql);
1212 
1313         Task Delete(Guid Id, string deleteSql);
1414 
1515         Task<List<T>> Select(string selectSql);
1616 
1717         Task<T> Detail(Guid Id, string detailSql);
1818 
1919         /// <summary>
2020         /// 无参存储过程
2121         /// </summary>
2222         /// <param name="SPName"></param>
2323         /// <param name="args"></param>
2424         /// <returns></returns>
2525         Task<List<T>> ExecQuerySP(string SPName);
2626     }
2727 }

5、仓储基实现类RepositoryBase继承仓储基接口，简单实现增删改查和无参的存储过程

1 1 using Dapper;
2 2 using System;
3 3 using System.Collections.Generic;
4 4 using System.Data;
5 5 using System.Linq;
6 6 using System.Threading.Tasks;
7 7 
8 8 namespace Dinner.Dapper
9 9 {
1010     public class RepositoryBase<T> : IRepositoryBase<T>
1111     {
1212         public async Task Delete(Guid Id, string deleteSql)
1313         {
1414             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
1515             {
1616                 await conn.ExecuteAsync(deleteSql, new { Id = Id });
1717             }
1818         }
1919 
2020         public async Task<T> Detail(Guid Id, string detailSql)
2121         {
2222             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
2323             {
2424                 //string querySql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users WHERE Id=@Id";
2525                 return await conn.QueryFirstOrDefaultAsync<T>(detailSql, new { Id = Id });
2626             }
2727         }
2828 
2929         /// <summary>
3030         /// 无参存储过程
3131         /// </summary>
3232         /// <param name="SPName"></param>
3333         /// <returns></returns>
3434         public async Task<List<T>> ExecQuerySP(string SPName)
3535         {
3636             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
3737             {
3838                 return await Task.Run(() => conn.Query<T>(SPName, null, null, true, null, CommandType.StoredProcedure).ToList());
3939             }
4040         }
4141 
4242         public async Task Insert(T entity, string insertSql)
4343         {
4444             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
4545             {
4646                 await conn.ExecuteAsync(insertSql, entity);
4747             }
4848         }
4949 
5050         public async Task<List<T>> Select(string selectSql)
5151         {
5252             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
5353             {
5454                 //string selectSql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users";
5555                 return await Task.Run(()=>conn.Query<T>(selectSql).ToList());
5656             }
5757         }
5858 
5959         public async Task Update(T entity, string updateSql)
6060         {
6161             using (IDbConnection conn = DataBaseConfig.GetSqlConnection())
6262             {
6363                 await conn.ExecuteAsync(updateSql, entity);
6464             }
6565         }
6666     }
6767 }

上面这些就是底层基本的封装，下一节我们来添加实体和仓储
