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
1 namespace Dinner.Dapper 2 { 3 public interface IEntity<TPrimaryKey> 4 { 5 TPrimaryKey Id { get; set; } 6 } 7 }
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
1 using System; 2 3 namespace Dinner.Dapper 4 { 5 public class BaseModel : IEntity<Guid> 6 { 7 public Guid Id { get; set; } 8 } 9 }
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 using StackExchange.Redis; 2 using System.Data; 3 using System.Data.SqlClient; 4 5 namespace Dinner.Dapper 6 { 7 public class DataBaseConfig 8 { 9 #region SqlServer链接配置 10 11 private static string DefaultSqlConnectionString = @"Data Source=localhost;Initial Catalog=Dinner;User ID=sa;Password=123456;"; 12 private static string DefaultRedisString = "localhost, abortConnect=false"; 13 private static ConnectionMultiplexer redis; 14 15 public static IDbConnection GetSqlConnection(string sqlConnectionString = null) 16 { 17 if (string.IsNullOrWhiteSpace(sqlConnectionString)) 18 { 19 sqlConnectionString = DefaultSqlConnectionString; 20 } 21 IDbConnection conn = new SqlConnection(sqlConnectionString); 22 conn.Open(); 23 return conn; 24 } 25 26 #endregion 27 28 #region Redis链接配置 29 30 private static ConnectionMultiplexer GetRedis(string redisString = null) 31 { 32 if (string.IsNullOrWhiteSpace(redisString)) 33 { 34 redisString = DefaultRedisString; 35 } 36 if (redis == null || redis.IsConnected) 37 { 38 redis = ConnectionMultiplexer.Connect(redisString); 39 } 40 return redis; 41 } 42 43 #endregion 44 } 45 }
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 using System; 2 using System.Collections.Generic; 3 using System.Threading.Tasks; 4 5 namespace Dinner.Dapper 6 { 7 public interface IRepositoryBase<T> 8 { 9 Task Insert(T entity, string insertSql); 10 11 Task Update(T entity, string updateSql); 12 13 Task Delete(Guid Id, string deleteSql); 14 15 Task<List<T>> Select(string selectSql); 16 17 Task<T> Detail(Guid Id, string detailSql); 18 19 /// <summary> 20 /// 无参存储过程 21 /// </summary> 22 /// <param name="SPName"></param> 23 /// <param name="args"></param> 24 /// <returns></returns> 25 Task<List<T>> ExecQuerySP(string SPName); 26 } 27 }
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 using Dapper; 2 using System; 3 using System.Collections.Generic; 4 using System.Data; 5 using System.Linq; 6 using System.Threading.Tasks; 7 8 namespace Dinner.Dapper 9 { 10 public class RepositoryBase<T> : IRepositoryBase<T> 11 { 12 public async Task Delete(Guid Id, string deleteSql) 13 { 14 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 15 { 16 await conn.ExecuteAsync(deleteSql, new { Id = Id }); 17 } 18 } 19 20 public async Task<T> Detail(Guid Id, string detailSql) 21 { 22 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 23 { 24 //string querySql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users WHERE Id=@Id"; 25 return await conn.QueryFirstOrDefaultAsync<T>(detailSql, new { Id = Id }); 26 } 27 } 28 29 /// <summary> 30 /// 无参存储过程 31 /// </summary> 32 /// <param name="SPName"></param> 33 /// <returns></returns> 34 public async Task<List<T>> ExecQuerySP(string SPName) 35 { 36 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 37 { 38 return await Task.Run(() => conn.Query<T>(SPName, null, null, true, null, CommandType.StoredProcedure).ToList()); 39 } 40 } 41 42 public async Task Insert(T entity, string insertSql) 43 { 44 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 45 { 46 await conn.ExecuteAsync(insertSql, entity); 47 } 48 } 49 50 public async Task<List<T>> Select(string selectSql) 51 { 52 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 53 { 54 //string selectSql = @"SELECT Id, UserName, Password, Gender, Birthday, CreateDate, IsDelete FROM dbo.Users"; 55 return await Task.Run(()=>conn.Query<T>(selectSql).ToList()); 56 } 57 } 58 59 public async Task Update(T entity, string updateSql) 60 { 61 using (IDbConnection conn = DataBaseConfig.GetSqlConnection()) 62 { 63 await conn.ExecuteAsync(updateSql, entity); 64 } 65 } 66 } 67 }
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
