asp.net - 如何注册通用存储库的依赖？

Question

我有以下存储库库:

public class FakeRepositoryBase<TEntity, TPrimaryKey> : AbpRepositoryBase<TEntity, TPrimaryKey>
    where TEntity : class, IEntity<TPrimaryKey>
{...}

并从第一个继承:

public class FakeRepositoryBase<TEntity> : FakeRepositoryBase<TEntity, int>, IRepository<TEntity>
    where TEntity : class, IEntity<int>
{...}

模块注册:

[DependsOn(typeof(AbpKernelModule))]
public class DERCFakeDALModule: AbpModule
{
    public override void Initialize()
    {
        IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
    }
}

然后我声明AppService:

class DocumentAppService : ApplicationService, IDocumentAppService
{
    private readonly IRepository<Document> _documentRepository;
    private readonly IObjectMapper _objectMapper;

    public DocumentAppService(
        IRepository<Document> documentRepository,
        IObjectMapper objectMapper)
    {
        _documentRepository = documentRepository;
        _objectMapper = objectMapper;
    }

    // AppService methods
}

并将所有依赖项添加到我的 WebModule:

[DependsOn(
        typeof(AbpWebMvcModule),
        typeof(DERCApplicationModule), 
        typeof(DERCWebApiModule),
        typeof(DERCFakeDALModule))]
public class DERCWebModule : AbpModule

调用任意API方法后，出现错误:

  "message": "An error has occurred.",
  "exceptionMessage": "ComponentActivator: could not proxy Abp.WebApi.Controllers.Dynamic.DynamicApiController`1[[DERC.ApplicationServices.Interfaces.IDocumentAppService, DERC.Application, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]",

  }
}

如何解决这个问题？

在检查基本约定注册时，您可以看到:

        //Transient
        context.IocManager.IocContainer.Register(
            Classes.FromAssembly(context.Assembly)
                .IncludeNonPublicTypes()
                .BasedOn<ITransientDependency>()
                .If(type => !type.GetTypeInfo().IsGenericTypeDefinition)
                .WithService.Self()
                .WithService.DefaultInterfaces()
                .LifestyleTransient()
            );

        //Singleton
        context.IocManager.IocContainer.Register(
            Classes.FromAssembly(context.Assembly)
                .IncludeNonPublicTypes()
                .BasedOn<ISingletonDependency>()
                .If(type => !type.GetTypeInfo().IsGenericTypeDefinition)
                .WithService.Self()
                .WithService.DefaultInterfaces()
                .LifestyleSingleton()
            );

        //Windsor Interceptors
        context.IocManager.IocContainer.Register(
            Classes.FromAssembly(context.Assembly)
                .IncludeNonPublicTypes()
                .BasedOn<IInterceptor>()
                .If(type => !type.GetTypeInfo().IsGenericTypeDefinition)
                .WithService.Self()
                .LifestyleTransient()
            );

这意味着首先您必须使用 ITransientDependency 或 ISingletonDependency 接口(interface)标记依赖项，以便能够按约定注册它们。然后无论如何，泛型类型都被排除在外，因此您必须通过标准方法注册它们:

IocManager.IocContainer.Register(Component.For(typeof(ITest<,>)).ImplementedBy(typeof(Test<,>)));
