使用Spring4D的依赖注入框架.

我尝试使用DynamicAbstractFactories.在测试中有2个类和工厂: IOrderShipper并且IOrderShipperFactory会工作, IDocument并且IDocumentFactory会失败.

程序TestDocument中的代码将引发

类型不满意的构造函数:DynamicAbstractFactory.TDocument

我不明白为什么......我希望有人知道原因,我觉得真的很蠢

program DynamicAbstractFactory;
{$APPTYPE CONSOLE}
uses
  System.Sysutils,
  Spring.Container;

type
  TEnum = (e1, e2, e3, e4, e5);

  IDocument = interface
    ['{CCB718EF-7670-4157-97FF-0E49ACBEB449}']
    procedure Show;
  end;

  IDocumentFactory = interface(IInvokable)
    ['{73ADE7C1-3119-45B6-B615-04A4079AA581}']
    function Create: IDocument; overload;
    function Create(ID: integer; DocType: TEnum; Level: integer): IDocument; overload;
  end;


  IOrderShipper = interface
    ['{F4653C0C-2C05-4348-A744-3288E520F586}']
    procedure Ship;
  end;

  IOrderShipperFactory = interface(IInvokable)
    ['{F632D1FB-9C34-48FD-BD72-6BBC436D1B47}']
    function Create: IOrderShipper; overload;
    function Create(const name: string): IOrderShipper; overload;
    function Create(aId: integer; en: TEnum; Level: …
