基于.NET 6.0 自研輕量級ORM框架

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、快速入門

1、手動創(chuàng)建

var?options?=?new?DefaultDbOptions()?//數(shù)據(jù)選項
????????????????{
????????????????????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(options);//原生Ado
????????????var?db?=?new?DbContext(ado);//數(shù)據(jù)庫上下文

2、依賴注入

var?builder?=?WebApplication.CreateBuilder(args);

//?正式項目請用配置文件注入,為了測試方便直接引用實(shí)現(xiàn)類庫

builder.Services.AddScoped<IAdo<DefaultDbOptions>,?Ado<DefaultDbOptions>>();
builder.Services.AddScoped<IDbContext<DefaultDbOptions>,?DbContext<DefaultDbOptions>>();

3、加載Json配置文件

builder.Services.Configure<DefaultDbOptions>(configuration.GetSection("DbFactory:MySqlDb"));

4、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;"
????}
??}

5、Controller 構(gòu)造方法注入已注冊的DbContext對象

namespace?Fast.Framework.Web.Test.Controllers
{
????[Route("api/[controller]/[action]")]
????[ApiController]
????public?class?ProductController?:?ControllerBase
????{

????????///?

????????///?數(shù)據(jù)庫
????????///?
????????private?readonly?IDbContext?db;

????????///?

????????///?日志
????????///?
????????private?readonly?ILogger?logger;

????????///?

????????///?構(gòu)造方法
????????///?
????????///?
????????public?ProductController(ILogger?logger,?IDbContext?db)
????????{
????????????this.db?=?db;
????????????this.logger?=?logger;
????????}
????}
}
