Question

我有以下存储库基础：

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

继承自第一个：

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());
    }
}

然后我宣布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中：

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

调用任何API方法后，都会出现错误：

如何解决这个问题？

检查基本会议注册时，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()
            );

这意味着首先必须使用ITransientDependency或ISingletonDependency接口来标记依赖关系，以便能够按约定注册它们。然后无论如何都会排除泛型类型，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<,>)));

如何注册通用存储库的依赖？
