我有以下存储库库：
public class FakeRepositoryBase<TEntity, TPrimaryKey> : AbpRepositoryBase<TEntity, TPrimaryKey>
where TEntity : class, IEntity<TPrimaryKey>
{...}
并继承自第一个：
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：

我该如何解决这个问题？
检查什么基本约定注册时，您会看到：
//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()
);
这意味着首先必须用ITransientDependency或ISingletonDependency接口标记依赖项，以便能够按约定注册它们。然后无论如何泛型类型都会被排除，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<,>)));
