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
