EasyCore.EFCoreRepository 1.0.0

EasyCore.EFCoreRepository

Repository 是软件开发中的一个重要概念，尤其在 领域驱动设计（DDD） 和 数据访问层 中广泛使用。Repository 是一种 抽象数据访问层的设计模式，它封装了数据访问逻辑，使上层业务逻辑与底层数据存储解耦。Repository 就像是数据仓库的接口，用于管理实体对象的持久化（增删改查）操作。

使用说明：

1.Program注册

 public class Program
 {
     public static void Main(string[] args)
     {
         var builder = WebApplication.CreateBuilder(args);

         builder.Services.AddControllers();
         builder.Services.AddEndpointsApiExplorer();
         builder.Services.AddSwaggerGen();
         builder.Services.EasyCoreDependencie();
         builder.Services.AddDbContext<TestDbContext>();

         // Use EasyCore EFCore Repository
         builder.Services.EasyCoreEFCoreRepository();

         var app = builder.Build();

         if (app.Environment.IsDevelopment())
         {
             app.UseSwagger();
             app.UseSwaggerUI();
         }

         app.UseAuthorization();


         app.MapControllers();

         app.Run();
     }
 }

2.实体继承

EasyCore.EFCoreRepository 提供了一个实体基类EasyCoreEntity，包含并发标记/软删除/以及多租户ID。

    public class TestEntity : EasyCoreEntity
    {
        [Key]
        public Guid Guid { get; set; }

        public string Name { get; set; }

        public int Age { get; set; }
    }

3.仓储类继承

EasyCore.EFCoreRepository 提供了一个仓储基类 EfCoreRepository<TDbContext, TEntity> 和仓储抽象 IRepository<TEntity>。

    public interface ITestEntityRepository : IRepository<TestEntity>, ITransientDependencie
    {

    }

（注：ITransientDependencie为EasyCore.Dependencie中的自动注入细节与抽象的依赖关系）

  public class TestEntityRepository : EfCoreRepository<TestDbContext, TestEntity>, ITestEntityRepository
  {
      public TestEntityRepository(TestDbContext dbContext, IServiceProvider serviceProvider) : base(dbContext, serviceProvider)
      {

      }
  }

4.使用仓储

 [Route("api/[controller]")]
 [ApiController]
 public class RepositoryController : ControllerBase
 {
     private readonly ITestEntityRepository _repository;

     public RepositoryController(ITestEntityRepository repository) => _repository = repository;

     [HttpGet]
     public async Task<TestEntity> Get()
     {
         return await _repository.GetAsync(e => e.Name == "Test");
     }

     [HttpPost]
     public async Task Post()
     {
         await _repository.InsertAsync(new EFCore.Entity.TestEntity { Name = "Test", Age = 10, Guid = Guid.NewGuid() }, true);
     }

     [HttpPut]
     public async Task Put()
     {
         var entity = await _repository.GetAsync(e => e.Name == "Test");

         entity.Age = 20;

         await _repository.UpdateAsync(entity, true);
     }

     [HttpDelete]
     public async Task Delete()
     {
         var entity = await _repository.GetAsync(e => e.Age == 20);

         entity.IsDeleted = true;

         await _repository.UpdateAsync(entity, true);
     }
 }

EasyCore.EFCoreRepository就可以自动实现实体的CURD操作。
