仓储

仓储提供了实体到数据库的存取能力，底层使用了EntityFrameworkCore作为具体的实现。

创建仓储

1. 添加nuget包NetCorePal.Extensions.Repository.EntityFrameworkCore：

   dotnet add package NetCorePal.Extensions.Repository.EntityFrameworkCore
   

2. 定义仓储

   using NetCorePal.Extensions.Repository;
   using NetCorePal.Extensions.Repository.EntityFrameworkCore;
   
   namespace YourRepositoryNamespace;
   
   
   //仓储接口（可选），可以不定义仓储接口，仅定义仓储类。
   public interface IOrderRepository : IRepository<Order, OrderId>
   {
   }
   
   //仓储实现
   public class OrderRepository : RepositoryBase<Order, OrderId, ApplicationDbContext>, IOrderRepository
   {
       public OrderRepository(ApplicationDbContext context) : base(context)
       {
       }
   }
   

3. 在Program.cs中注册仓储

   using NetCorePal.Extensions.Repository.EntityFrameworkCore;
   using Microsoft.EntityFrameworkCore;
   using Microsoft.Extensions.DependencyInjection;
   
   namespace YourStartupNamespace;
   
   var builder = WebApplication.CreateBuilder(args);
   builder.Services.AddDbContext<ApplicationDbContext>(options =>
   {
       options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
   });
   
   //注册仓储
   builder.Services.AddRepositories(typeof(OrderRepository).Assembly);
   
   //注册UnitOfWork
   builder.Services.AddUnitOfWork<ApplicationDbContext>();
   

   备注： 仓储类将被注册为Scoped生命周期。
