我确信我的配置中缺少一些东西.

这是我在导航到以下时遇到的错误：https：// localhost：44305 / api / integration

以下是一些相关的代码：

IoC Bootstrapper：

public static class Bootstrapper
{
    public static void Initialize()
    {
        var builder = new ContainerBuilder();

        builder.RegisterControllers(Assembly.GetExecutingAssembly());
        builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

        builder.Register(x => new SharePointContext(HttpContext.Current.Request)).As<ISharePointContext>().SingleInstance();
        builder.RegisterType<SharePointRepository<IEntity>>().As<IRepository<IEntity>>();
        builder.RegisterType<SharePointContextFilter>().SingleInstance();

        builder.RegisterFilterProvider();

        IContainer container = builder.Build();
        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

        var resolver = new AutofacWebApiDependencyResolver(container);
        GlobalConfiguration.Configuration.DependencyResolver = resolver;
    }
}

IRepository：

public interface IRepository<T>
{
    void Add(T entity);

    void Delete(int id);

    IEnumerable<T> Find(Expression<Func<T,bool>> filter = null);

    void Update(int id,T entity);
}

SharePointRepository：

internal class SharePointRepository<T> : IRepository<T> where T : IEntity
{
    private readonly ISharePointContext _context;
    private readonly string _listName;

    internal SharePointRepository(ISharePointContext context)
    {
        _context = context;

        object[] attributes = typeof (T).GetCustomAttributes(typeof (SharePointListAttribute),false);

        if (!attributes.Any())
        {
            throw new Exception("No associated SharePoint list defined for " + typeof (T));
        }

        _listName = ((SharePointListAttribute) attributes[0]).ListName;
    }

    public void Add(T entity)
    {
        throw new NotImplementedException();
    }

    public void Delete(int id)
    {
        throw new NotImplementedException();
    }

    public IEnumerable<T> Find(Expression<Func<T,bool>> filter)
    {
        throw new NotImplementedException();
    }

    public void Update(int id,T entity)
    {
        throw new NotImplementedException();
    }
}

IntegrationController：

public class IntegrationController : ApiController
{
    private readonly IRepository<Integration> _repository;

    public IntegrationController(IRepository<Integration> repository)
    {
        _repository = repository;
    }

    public void Delete(Guid integrationId)
    {
        _repository.Delete(Get(integrationId).Id);
    }

    public IEnumerable<Integration> Get()
    {
        return _repository.Find();
    }

    public Integration Get(Guid integrationId)
    {
        return _repository.Find(i => i.IntegrationId == integrationId).FirstOrDefault();
    }

    public void Post([FromBody] Integration integration)
    {
        _repository.Add(integration);
    }

    public void Put(Guid integrationId,[FromBody] Integration integration)
    {
        _repository.Update(Get(integrationId).Id,integration);
    }
}

IEntity：

internal interface IEntity
{
    int Id { get; }
}

实体：

public abstract class Entity : IEntity
{
    protected Entity(int id)
    {
        Id = id;
    }

    public int Id { get; private set; }
}

积分：

[SharePointList("Integrations")]
public class Integration : Entity
{
    public Integration(int id) : base(id)
    {
    }

    public string ApiUrl { get; set; }

    public bool DeletionAllowed { get; set; }

    public Guid IntegrationId { get; set; }

    public string Key { get; set; }

    public string List { get; set; }

    public bool OutgoingAllowed { get; set; }

    public string RemoteWeb { get; set; }

    public string Web { get; set; }
