SqlSugard封装
1、创建 IDbContext.cs
using SqlSugar; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace BoZhon.Data.SqlSugar.DbContext { public interface IDbContext { /// <summary> /// 操作数据库对象 /// </summary> SqlSugarClient db { get; } /// <summary> /// 创建数据表 /// </summary> /// <param name="Backup">是否备份</param> /// <param name="StringDefaultLength">string类型映射的长度</param> /// <param name="types">要创建的数据表</param> void CreateTable(bool Backup = false, int StringDefaultLength = 50, params Type[] types); /// <summary> /// 创建表 /// </summary> /// <param name="Backup">是否备份</param> /// <param name="StringDefaultLength">string类型映射的长度</param> void CreateAllTable(bool Backup = false, int StringDefaultLength = 50); } }
2、创建 AppDbContext.cs ，实现 IDbContext
using BoZhon.Util; using SqlSugar; using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Reflection; using System.Text; using System.Threading.Tasks; namespace BoZhon.Data.SqlSugar.DbContext { /// <summary> /// 数据库上下文 /// </summary> public class AppDbContext : IDbContext { //获取配置文件中的连接属性 private string DBConnectionString = Configs.GetValue("DBConnectionString"); private string DBProvider = Configs.GetValue("DBProvider"); /// <summary> /// 返回数据库类型实例 /// </summary> /// <returns></returns> private DbType getdbType() { switch (DBProvider) { case "MySql": return DbType.MySql; case "SqlServer": return DbType.SqlServer; case "Sqlite": return DbType.Sqlite; case "Oracle": return DbType.Oracle; default: throw new Exception("数据库类型目前不支持！"); } } /// <summary> /// 操作数据库对象 /// </summary> public SqlSugarClient db { get { return new SqlSugarClient(new ConnectionConfig() { ConnectionString = DBConnectionString, DbType = getdbType(), IsAutoCloseConnection = true, InitKeyType = InitKeyType.Attribute, AopEvents= new AopEvents { OnLogExecuting = (sql, paramster) => { //string sa = sql; Debug.Print(sql + $"\r\n" + $"{db.Utilities.SerializeObject(paramster.ToDictionary(it => it.ParameterName, it => it.Value))} \r\n"); } } }); } } /// <summary> /// 创建数据表 /// </summary> /// <param name="Backup">是否备份</param> /// <param name="StringDefaultLength">string类型映射的长度</param> /// <param name="types">要创建的数据表</param> public void CreateTable(bool Backup = false, int StringDefaultLength = 50, params Type[] types) { //设置varchar的默认长度 db.CodeFirst.SetStringDefaultLength(StringDefaultLength); //创建表 if (Backup) { db.CodeFirst.BackupTable().InitTables(types); } else { db.CodeFirst.InitTables(types); } } /// <summary> /// 创建表 /// </summary> /// <param name="Backup">是否备份</param> /// <param name="StringDefaultLength">string类型映射的长度</param> public void CreateAllTable(bool Backup = false, int StringDefaultLength = 50) { //设置varchar的默认长度 db.CodeFirst.SetStringDefaultLength(StringDefaultLength); Assembly assembly = Assembly.Load("SqlSugar.Model"); Type[] types = assembly.GetTypes().Where(t => t.FullName.Contains("Models")).ToArray(); bool b = db.DbMaintenance.CreateDatabase(); //创建表 if (Backup) { db.CodeFirst.BackupTable().InitTables(types); } else { db.CodeFirst.InitTables(types); } } } }
3、创建仓储 IBaseRepository.cs
