.NET Repository 패턴
데이터 접근 계층을 추상화하는 Repository 패턴 구현 가이드입니다.
1. 프로젝트 구조
MyApp/
├── Program.cs
├── App.cs
├── Models/
│ └── User.cs
├── Repositories/
│ ├── IUserRepository.cs
│ └── UserRepository.cs
├── Services/
│ ├── IUserService.cs
│ └── UserService.cs
└── GlobalUsings.cs
2. Model 정의
namespace MyApp.Models;
public sealed record User(int Id, string Name, string Email);
3. Repository 계층
3.1 인터페이스
namespace MyApp.Repositories;
public interface IUserRepository
{
Task<List<User>> GetAllAsync();
Task<User?> GetByIdAsync(int id);
Task AddAsync(User user);
Task UpdateAsync(User user);
Task DeleteAsync(int id);
}
3.2 구현체
namespace MyApp.Repositories;
public sealed class UserRepository : IUserRepository
{
private readonly List<User> _users = [];
public Task<List<User>> GetAllAsync()
{
return Task.FromResult(_users.ToList());
}
public Task<User?> GetByIdAsync(int id)
{
return Task.FromResult(_users.FirstOrDefault(u => u.Id == id));
}
public Task AddAsync(User user)
{
_users.Add(user);
return Task.CompletedTask;
}
public Task UpdateAsync(User user)
{
var index = _users.FindIndex(u => u.Id == user.Id);
if (index >= 0) _users[index] = user;
return Task.CompletedTask;
}
public Task DeleteAsync(int id)
{
_users.RemoveAll(u => u.Id == id);
return Task.CompletedTask;
}
}
4. Service 계층
4.1 인터페이스
namespace MyApp.Services;
public interface IUserService
{
Task<IReadOnlyList<User>> GetAllUsersAsync();
Task<User?> GetUserByIdAsync(int id);
}
4.2 구현체
namespace MyApp.Services;
public sealed class UserService(IUserRepository repository) : IUserService
{
private readonly IUserRepository _repository = repository;
public async Task<IReadOnlyList<User>> GetAllUsersAsync()
{
var users = await _repository.GetAllAsync();
return users.AsReadOnly();
}
public Task<User?> GetUserByIdAsync(int id)
{
return _repository.GetByIdAsync(id);
}
}
5. DI 등록
var host = Host.CreateDefaultBuilder(args)
.ConfigureServices(services =>
{
// Repository 등록
services.AddSingleton<IUserRepository, UserRepository>();
// Service 등록
services.AddSingleton<IUserService, UserService>();
services.AddSingleton<App>();
})
.Build();
6. Generic Repository (선택적)
public interface IRepository<T> where T : class
{
Task<List<T>> GetAllAsync();
Task<T?> GetByIdAsync(int id);
Task AddAsync(T entity);
Task UpdateAsync(T entity);
Task DeleteAsync(int id);
}
7. 계층 구조
App (Presentation)
↓
Service Layer (비즈니스 로직)
↓
Repository Layer (데이터 접근)
↓
Data Source (DB, API, File 등)
8. 핵심 원칙
- Repository는 데이터 접근만 담당
- 비즈니스 로직은 Service에 작성
- 인터페이스로 추상화하여 테스트 용이성 확보
- Constructor Injection으로 의존성 주입
