无法创建组件，因为它具有要满足的依赖关系 [英] Can't create component as it has dependencies to be satisfied

问题描述

我正在学习DDD，n-Tier，存储库等.有人将我指向ASP.NET Boilerplate，因此我决定使用该项目启动一个测试项目.我从未处理过依赖注入，因此这对我来说是全新的，但是它使用ius Castle Windsor的DI依赖.现在，我创建了一个模型，并从该模型中创建了一个接口.我还添加了服务.每当我启动应用程序时，都会出现此错误:

I am learning DDD, n-Tier, Repositoriess and the likes. Someone pointed me to ASP.NET Boilerplate and I decided to start a test project using that. I have never dealt with dependency injection so this is all new to me, but the DI dependency it uses ius Castle Windsor. Now, I created a Model and from this Model I created an interface. I also added a Service. Whenever I fire up the app it gives me this error:

Can't create component 'TestApp.Services.MemberInfo.MemberAppService'
as it has dependencies to be satisfied.

'TestApp.Services.MemberInfo.MemberAppService' is waiting for the following dependencies:
- Service 'TestApp.Repositories.IMemberInfoRepository' which was not registered.

我知道您必须注册服务之类的东西，但是在这里阅读ABP文档说， http://www.aspnetboilerplate.com/Pages/Documents/Dependency-Injection#DocAbpInfrastructure ，如果您将App添加到类名中，则会自动注册它们.基本上，这是我的代码:

I know you've got to register services and the likes, but reading ABPs documentation it says here, http://www.aspnetboilerplate.com/Pages/Documents/Dependency-Injection#DocAbpInfrastructure, that they are registered automatically if you add App to the name of the class. Basically, this is my code:

IMemberInfoRepository

IMemberInfoRepository

    public interface IMemberInfoRepository : IRepository<MemberInfo, Guid>
{

}

MemberAppService

MemberAppService

 public class MemberAppService : IMemberAppService
{
    private readonly Repositories.IMemberInfoRepository _memberInfoRepository;

    public MemberAppService(Repositories.IMemberInfoRepository memberInfoRepository)
    {
        _memberInfoRepository = memberInfoRepository;
    }

    public void Create(MemberInfoDto input)
    {
      _memberInfoRepository.Insert(AutoMapper.Mapper.Map<m.MemberInfo>(input));
    }

IMemberAppService

IMemberAppService

public interface IMemberAppService :IApplicationService
{
    void Create(MemberInfoDto input);
}

所以，我在这里.卡住.我阅读了温莎城堡的一些官方文档，但由于这是我的第一个牛仔竞技表演，因此我坚持要做的事情.其他任何东西都将不胜感激.

So, here I am. Stuck. I read some Castle Windsor official documentation but as this is my first rodeo with this I am stuck at on what to do. Anything else would be greatly appreciated.

推荐答案

我遇到了同样的问题，但我可以解决！

I had the same problem but I could solve it!

这是IIS给出的错误的屏幕截图.

This is a screenshot of the error given by IIS.

错误的原因是ABP无法找到已定义的实体类Member.

The reason of the error is that ABP cannot find the defined entity class Member.

解决方案是在EntityFramework项目的DbContext中添加代码public virtual IDbSet<Members> Members { set; get; }.

The solution was to add the code public virtual IDbSet<Members> Members { set; get; }in the DbContext of the EntityFramework Project.
