一、前言

1.为了实现快速开发,省去编写大量Sql时间,更好的面向对象编程由此诞生了 Fast Framework

2.Fast Framework 是一个基于NET6.0 封装的轻量级 ORM 框架 支持数据库 SqlServer Oracle MySql PostgreSql Sqlite 由于底层使用System.Data.Common 抽象类封装 理论支持所有Ado.Net 实现的类库,差异部分可能需要额外处理。

3.框架 优点: 体积小 流畅API 使用更加简单 性能高 缺点:不具备有自动建库建表迁移等复杂的功能 由于不同数据库差异较大 实现较为复杂 所以暂时不考虑实现

二、项目明细 (后缀为Test均为测试项目)

  1. Fast.Framework
  2. Fast.Framework.CustomAttribute
  3. Fast.Framework.Extensions
  4. Fast.Framework.Interfaces
  5. Fast.Framework.Logging
  6. Fast.Framework.Models
  7. Fast.Framework.Utils

三、快速入门

  1. 手动创建
var options = new DefaultDbOptions() //数据选项
                {
                    DbType = DbType.MySQL,
                    ProviderName = "MySqlConnector",
                    FactoryName = "MySqlConnector.MySqlConnectorFactory,MySqlConnector",
                    ConnectionStrings = "server=localhost;database=Test;user=root;pwd=123456789;port=3306;min pool size=3;max pool size=100;connect timeout =30;AllowLoadLocalInfile=True;"
                };
            var ado = new Ado<DefaultDbOptions>(options);//原生Ado
            var db = new DbContext<DefaultDbOptions>(ado);//数据库上下文
  1. 依赖注入
var builder = WebApplication.CreateBuilder(args);

// 正式项目请用配置文件注入,为了测试方便直接引用实现类库

builder.Services.AddScoped<IAdo<DefaultDbOptions>, Ado<DefaultDbOptions>>();
builder.Services.AddScoped<IDbContext<DefaultDbOptions>, DbContext<DefaultDbOptions>>();
  1. 加载Json配置文件
builder.Services.Configure<DefaultDbOptions>(configuration.GetSection("DbFactory:MySqlDb"));
  1. Json 格式
"DbFactory": {
    "MySQLDb": {
      "DbType": "MySQL",
      "ProviderName": "MySqlConnector",
      "FactoryName": "MySqlConnector.MySqlConnectorFactory,MySqlConnector",
      "ConnectionStrings": "server=localhost;database=Test;user=root;pwd=123456789;port=3306;min pool size=3;max pool size=100;connect timeout =30;"
    },
    "SQLServerDb": {
      "DbType": "SQLServer",
      "ProviderName": "System.Data.SqlClient",
      "FactoryName": "System.Data.SqlClient.SqlClientFactory,System.Data",
      "ConnectionStrings": "server=localhost;database=Test;user=sa;pwd=123456789;min pool size=3;max pool size=100;connect timeout =30;"
    },
    "OracleDb": {
      "DbType": "Oracle",
      "ProviderName": "Oracle.ManagedDataAccess.Client",
      "FactoryName": "Oracle.ManagedDataAccess.Client.OracleClientFactory,Oracle.ManagedDataAccess",
      "ConnectionStrings": "data source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=ORCL)));user id=system;password=Oracle2022;min pool size=3;max pool size=100;connect timeout =30;"
    },
    "PostgreSQLDb": {
      "DbType": "PostgreSQL",
      "ProviderName": "Npgsql",
      "FactoryName": "Npgsql.NpgsqlFactory,Npgsql",
      "ConnectionStrings": "host=localhost;database=test;userid=postgres;pwd=123456789;port=5432;"
    },
    "SQLiteDb": {
      "DbType": "SQLite",
      "ProviderName": "System.Data.SQLite",
      "FactoryName": "System.Data.SQLite.SQLiteFactory,System.Data.SQLite",
      "ConnectionStrings": "data source=mysqlite.db;pooling=true;"
    }
  }
  1. Controller 构造方法注入已注册的DbContext对象
namespace Fast.Framework.Web.Test.Controllers
{
    [Route("api/[controller]/[action]")]
    [ApiController]
    public class ProductController : ControllerBase
    {

        /// <summary>
        /// 数据库
        /// </summary>
        private readonly IDbContext<DefaultDbOptions> db;

        /// <summary>
        /// 日志
        /// </summary>
        private readonly ILogger<ProductController> logger;

        /// <summary>
        /// 构造方法
        /// </summary>
        /// <param name="db"></param>
        public ProductController(ILogger<ProductController> logger, IDbContext<DefaultDbOptions> db)
        {
            this.db = db;
            this.logger = logger;
        }
    }
}
