Acme.EFCore.Small

一、概述

Acme.EFCore.Small是一款轻量级的EFCore通用类库，旨在使用 Entity Framework Core（EFCore）与数据库进行交互。它作为处理各种数据库操作的基础组件。

二、入门指南

1.安装Acme.EFCore.Small

创建项目 → 点击引用 → 右键 → 管理Nuget程序包->搜索Acme.EFCore.Small选择对应版本的.NET版本安装即可。

2.安装对应数据库包

  • SqlServer: Microsoft.EntityFrameworkCore.SqlServer
  • Sqlite: Microsoft.EntityFrameworkCore.Sqlite
  • Cosmos: Microsoft.EntityFrameworkCore.Cosmos
  • InMemoryDatabase: Microsoft.EntityFrameworkCore.InMemory
  • MySql:
    • Pomelo.EntityFrameworkCore.MySql
    • MySql.EntityFrameworkCore
  • PostgreSQL: Npgsql.EntityFrameworkCore.PostgreSQL
  • Oracle: Oracle.EntityFrameworkCore
  • Firebird: FirebirdSql.EntityFrameworkCore.Firebird
  • Dm: Microsoft.EntityFrameworkCore.Dm

4.创建DbContext数据库上下文类

public class AppDbContext : DbContext
{
    /// <summary>
    /// 初始化数据库上下文
    /// </summary>
    /// <param name="options"></param>
    public AppDbContext(DbContextOptions<AppDbContext> options) :
       base(options)
    {
    }
}

5.配置连接字符串

{
    "ConnectionStrings":{
        "DefaultConnection": "Persist Security Info=False;Data Source=.;Initial Catalog=数据库名;User ID=用户;Password=密码;Connect Timeout=120;Encrypt=False;"
    }
}

6.依赖注入

6.1.基础配置
//调用数据库配置信息
services.AddDbContext<AppDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
//注入基础类IBaseService
services.AddBaseService<AppDbContext>();
//注入仓储类
services.AddRepository();
//注入静态Db类
services.AddDbExtension();
6.2.多库配置
//调用数据库配置信息
services.AddDbContext<AppDbContext1>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection1")));
//注入基础类IBaseService,传入数据库上下文进行注入
services.AddBaseService();

7.使用

    /// <summary>
    /// 用户控制器
    /// </summary>
    public class UserController : BaseController
    {
        private readonly IRepository<UserInfo> _userRepository;
        //构造函数注入
        public UserController(IRepository<UserInfo> userRepository)
        {
            _userRepository=userRepository;
        }

        public void Operate(UserInfo user)
        {
            //新增
            _userRepository.Add(info);
            //删除
            _userRepository.Delete(info);
            //查询
            _userRepository.GetList(info);
        }
    }

4.静态模式

//单库
Db.GetRepository<T>();

//多库
Db.GetRepository<TDbContext, T>();

5.联合查询

var userList = await (from user in _userRepository.GetQueryable(s => s.UserRole == UserRoleEnum.ZH)
                      join cqal in _cqalRepository.GetQueryable(s => s.State == CqalStateEnum.TG)
                      on user.UserId equals cqal.UserId
                      join price in _priceRepository.GetQueryable()
                      on user.UserId equals price.UserId
                      select user)
.ToListAsync();

6.事务,基础类中提供事务的开启，提交，回滚，关闭
