无法创建组件，因为它在 ASP.NET 样板中需要满足依赖关系

Question

我在运行测试时遇到错误。我该如何解决？

public class TestAppService : TestAppServiceBase, ITestAppService
{
    private readonly ITestRepository _testRepository;
    public TestAppService(ITestRepository testRepository)
    {
        _testRepository = testRepository;
    }
}

public class TestAppService_Test : TestAppServiceTestBase
{
    private readonly ITestAppService _testAppService;
    public TestAppService_Test()
    {
        _testAppService = Resolve<ITestAppService>();
    }
}

存储库：

public class TestRepository : TestRepositoryBase<Test, int>, ITestRepository
{
    private readonly IActiveTransactionProvider _transactionProvider;
    public TestRepository(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }

    public TestRepository(IDbContextProvider<TestDbContext> dbContextProvider,
        IActiveTransactionProvider transactionProvider, IObjectMapper objectMapper)
    : base(dbContextProvider)
    {
        _transactionProvider = transactionProvider;
        ObjectMapper = objectMapper;
    }
}

public interface ITestRepository : IRepository<Test, int>
{
}

public class TestRepositoryBase<TEntity, TPrimaryKey> : EfCoreRepositoryBase<TestDbContext, TEntity, TPrimaryKey>
    where TEntity : class, IEntity<TPrimaryKey>
{
    public IObjectMapper ObjectMapper;
    public TestRepositoryBase(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}

/// <summary>
/// Base class for custom repositories of the application.
/// This is a shortcut of <see cref="TestRepositoryBase{TEntity,TPrimaryKey}"/> for <see cref="int"/> primary key.
/// </summary>
/// <typeparam name="TEntity">Entity type</typeparam>
public class TestRepositoryBase<TEntity> : TestRepositoryBase<TEntity, int>
    where TEntity : class, IEntity<int>
{
    public TestRepositoryBase(IDbContextProvider<TestDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}

错误：

Answer 1

Castle.MicroKernel.Handlers.HandlerException : Can't create component 'ABC.XYZ.Business.Services.PQR.TestAppService' as it has dependencies to be satisfied.

'ABC.XYZ.Business.Services.PQR.TestAppService' is waiting for the following dependencies:
- Service 'ABC.XYZ.Business.Repositories.Interfaces.ITestRepository' which was not registered.

在您的 DbContext 中添加 DbSet<Test>:

public class TestDbContext : AbpDbContext
{
    public DbSet<Test> Tests { get; set; }

    public TestDbContext(DbContextOptions<TestDbContext> options)
        : base(options)
    {
    }
}

将 AutoRepositoryTypes 添加到您的 DbContext:

[AutoRepositoryTypes(
    typeof(IRepository<>),
    typeof(IRepository<,>),
    typeof(TestRepositoryBase<>),
    typeof(TestRepositoryBase<,>)
)]
public class TestDbContext : AbpDbContext
{
    ...
}

Target does not implement interface Abp.Domain.Repositories.IRepository`1[[Abp.Localization.Appl‌icationLanguage, Abp.Zero.Common, Version=2.3.0.0, Culture=neutral, PublicKeyToken=null]] Parameter name: target

注册TestRepository:

Configuration.ReplaceService<IRepository<Test, int>>(() =>
{
    IocManager.IocContainer.Register(
        Component.For<IRepository<Test, int>, ITestRepository, TestRepository>()
            .ImplementedBy<TestRepository>()
            .LifestyleTransient()
    );
});

解释：

当您注入 ITestRepository 时，它会尝试按定义实例化 IRepository<Test, Int>。但是，您的 TestRepository 实现了您的自定义 TestRepositoryBase<Test, int>。因此，您需要通过注册您的具体 class.

来替换 IRepository<Test, Int>

参考：

https://aspnetboilerplate.com/Pages/Documents/Entity-Framework-Core#replacing-default-repositories

Missing type map configuration or unsupported mapping. Mapping types: TestDetailsDTO -> Test Abc.Xyz.Business.Dto.Tests.TestDetailsDTO -> Abc.Xyz.Business.Model.Taxes.Test

在 TestDetailsDTO 上添加 [AutoMap(Test)] 属性。

如果这不起作用，请尝试手动配置映射：

public class MyTestModule : AbpModule
{
    public override void PreInitialize()
    {
        Configuration.Modules.AbpAutoMapper().UseStaticMapper = false;
        Configuration.Modules.AbpAutoMapper().Configurators.Add(config =>
        {
            config.CreateMap<TestDetailsDTO, Test>();
            config.CreateMap<Test, TestDetailsDTO>();
        });
    }
}

Answer 2

我通过更正错字解决了这个问题。 Windsor 依赖注入似乎遵循严格的命名约定。

我的界面被命名为 ILeadStatusesAppService

我的具体对象被命名为 LeadStatusAppService

如您所见，我有单数状态和复数状态。在给他们两个复数名称（或单数）后它起作用了。

Answer 3

我遵循了 ABP 推荐的命名约定，但没有成功。我尝试再次重构代码，但没有成功。奇怪的是，一切都在调试中运行良好，但当我尝试发布或构建发布时，错误又回来了。

经过几天的调试和重构，我决定将Release文件夹与Debug进行对比。我注意到 Release 中的 Entity Framework Class Library 与 Debug 不同。日期不对。然后它点击了，它无法创建存储库的原因是它实际上不可用，因为 EF Class 库很旧并且在 Release 中没有，但在 Debug 中有。因此，我只是再次清理了所有内容，并确保 EF 在 Release 中构建了一个新的 DLL 并且它可以正常工作。

这似乎是一个容易解决的问题，但花了一些时间才弄清楚:)

Answer 4

我遇到了类似的问题，结果发现存在循环依赖情况。两种服务都被注入彼此的实例并等待解决。

我更正了这个错误并解决了。

Answer 5

我有同样的问题，但我意识到我只是忘记实现我创建的应用程序服务接口，当我从控制器调用它时，我得到了这个错误
