对泛型注入有支持吗？比如某些场景Repository<TEntity>

目前提示NAutowired.Core.Exceptions.UnableResolveDependencyException: Unable to resolve dependency

有代码片段或者样例吗

是否以下这种情况：

public interface IRepository
{
    string GetEntityName();
}

[NAutowired.Core.Attributes.Repository]
public class Repository<TEntity> : IRepository
{
    public string GetEntityName()
    {
        return typeof(TEntity).Name;
    }
}

//在控制器中想要还原出Repository<User>
public class UserController : ControllerBase
{
    [Autowired(typeof(Repository<User>))]
    private readonly IRepository userRepository;

    [HttpGet]
    public string Get()
    {
        return userRepository.GetEntityName();
    }
}

如果是上面这种情况，你有两种解决方案：

先决条件：NAutowired >= 2.0.1

• 在Startup.cs中，使用services.AddScoped(typeof(IRepository), typeof(Repository<User>))的方式注入到容器，然后在Controller使用[Autowired(typeof(Repository<User>))]还原，这意味着你没法使用程序集自动注入的方法，因为你的Repository<TEntity>是泛型，需要你一个个在Startup.cs注入到容器。

  
  // in Startup.cs
  public void ConfigureServices(IServiceCollection services)
  {
  services.AddControllers().AddControllersAsServices();
  //replace `IControllerActivator` implement.
  services.Replace(ServiceDescriptor.Transient<IControllerActivator, NAutowiredControllerActivator>());
  services.AddTransient<IRepository, Repository<User>>();
  //services.AddTransient<IRepository, Repository<OtherEntity>>();
  }

// in UserController [Autowired(typeof(Repository))] private readonly IRepository userRepository;

[HttpGet] public string Get() { return userRepository == null ? "failure" : "success"; }

* 另一种方案是您可以使用`UserRepository<User>`继承自`Repository<TEntity>`，并且用`[Repository(implementInterface: typeof(IRepository))]`的方式继续使用自动添加到容器的方法。
```csharp
// in UserRepository
[Repository(implementInterface: typeof(IRepository))]
public class UserRepository: Repository<User> 
{
}

// in Startup.cs
public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers().AddControllersAsServices();
    //replace `IControllerActivator` implement.
    services.Replace(ServiceDescriptor.Transient<IControllerActivator, NAutowiredControllerActivator>());
    //use auto dependency injection
    services.AutoRegisterDependency(assemblies);
}

// in UserController
[Autowired(typeof(UserRepository))]
private readonly IRepository userRepository;

[HttpGet]
public string Get()
{
    return userRepository == null ? "failure" : "success";
}

明白了，谢谢
