c# - 如何将具体类注册到通用接口(interface)？

Question

我尝试注册基于泛型类的具体类，而这个泛型类是基于泛型接口(interface)的。问题是如何在 CaSTLe Windsor 和 ASP.NET Boilerplate 中执行此操作，这样我就不需要很多代码来一一注册它。

public interface IService<T> where T: class ...

public class Service<T, TE, TPrimary> : IService<T> where T: class ...

public class ConcreteService : Service<SomeType, SomeType2, string> ...
public class AnotherConcreteService : Service<AnotherSomeType, AnotherSomeType2, string> ...

有了这样的结构，我想注册到IService<SomeType>类(class)ConcreteService ，它实现了这个服务。我怎么能用温莎城堡做到这一点？一个一个的实现看起来像这样:

IocManager.IocContainer.Register(Component.For(typeof(IQueryService<SomeType>))
    .ImplementedBy(typeof(ConcreteService)).Named("ConcreteTest"));

IocManager.IocContainer.Register(Component.For(typeof(IQueryService<AnotherSomeType>))
    .ImplementedBy(typeof(AnotherConcreteService)).Named("AnotherConcreteTest"));

我想要的用法:

var test1 = IocContainer.Resolve<IQueryService<SomeType>(); // Here should be ConcreteService
var test2 = IocContainer.Resolve<IQueryService<AnotherSomeType>(); // Here should be AnotherConcreteService

通过逐行方法，它可以工作，但如何根据 IQueryService<> 注册所有内容？

Answer 1

1。 IQueryService<SomeTypeDto>

Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service AbpCompanyName.AbpProjectName.IGenerics.IQueryService`1[[AbpCompanyName.AbpProjectName.SomeEntitiesDto.SomeTypeDto, AbpCompanyName.AbpProjectName.Application, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] was found

要将具体类注册到通用接口(interface)，请使用 .WithService.Base() .

与RegisterAssemblyByConvention 的兼容性¹ , 配置唯一名称。

public override void Initialize()
{
    var thisAssembly = ...

    IocManager.RegisterAssemblyByConvention(thisAssembly);

    IocManager.IocContainer.Register(
        Classes.FromAssembly(thisAssembly)
            .BasedOn(typeof(IQueryService<>))
            .WithService.Base()
            .Configure(configurer => configurer.Named(Guid.NewGuid().ToString())) // Add this
    );

    // ...
}

¹ 如果您的具体类实现了 ASP.NET Boilerplate 的 ITransientDependency , 然后使用默认名称为 .WithService.Self() 注册类里面RegisterAssemblyByConvention .

2。 IRepository<SomeType>

Castle.MicroKernel.Handlers.HandlerException: Can't create component 'AbpCompanyName.AbpProjectName.SomeEntityService.SomeTypeService' as it has dependencies to be satisfied.

'AbpCompanyName.AbpProjectName.SomeEntityService.SomeTypeService' is waiting for the following dependencies:
- Service 'Abp.Domain.Repositories.IRepository`1[[AbpCompanyName.AbpProjectName.SomeEntities.SomeType, AbpCompanyName.AbpProjectName.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' which was not registered.

要使用 ASP.NET Boilerplate 存储库，请定义一个public DbSet。

public class AbpProjectNameDbContext : ...
{
    /* Define a DbSet for each entity of the application */

    // DbSet<SomeType> SomeEntities { get; set; }     // Remove this
    public DbSet<SomeType> SomeEntities { get; set; } // Add this

    // ...
}
