我在Spring4d容器中注册了许多对象，有些是Singleton。当应用程序关闭时，几乎Singleton正确调用自己的销毁，但有些没有，FastMM报告内存泄漏。我正在寻找一种方法，如何记录哪些对象有问题。我尝试用这个简单的例子与容器扩展有经验：

unit Spring.Container.HCV.Extension;

interface

uses
  Spring.Container.Extensions, Spring.Container.Core, Spring.Container.Builder;

type
  THCVLoggerBuilderInspector = class(TInspectorBase)
  protected
    procedure DoProcessModel(const kernel: IKernel; const model: TComponentModel); override;
  end;

  TFakeBuilderInspector = class(TInspectorBase)
  protected
    procedure DoProcessModel(const kernel: IKernel; const model: TComponentModel);
        override;
  end;

  THCVLoggerExtension = class(TContainerExtension)
  protected
    procedure Initialize; override;
  end;

implementation
uses
  Spring.Container.Common;

procedure THCVLoggerBuilderInspector.DoProcessModel(const kernel: IKernel;
    const model: TComponentModel);
var
  lLT:string;
begin
  if model.ComponentType.IsInstance then
  begin
    case model.LifetimeType of
      TLifetimeType.Unknown:            lLT:='Unknown           ';
      TLifetimeType.Singleton:          lLT:='Singleton         ';
      TLifetimeType.Transient:          lLT:='Transient         ';
      TLifetimeType.PerResolve:         lLT:='PerResolve        ';
      TLifetimeType.SingletonPerThread: lLT:='SingletonPerThread';
      TLifetimeType.Pooled:             lLT:='Pooled            ';
      TLifetimeType.Custom:             lLT:='Custom            ';
    else
    end;
    kernel.Logger.Info('Builder: [%s] %s',[lLT,model.ComponentTypeName]);
  end;
end;

procedure THCVLoggerExtension.Initialize;
begin
  Kernel.Builder.AddInspector(THCVLoggerBuilderInspector.Create);
  Kernel.Builder.AddInspector(TFakeBuilderInspector.Create);
end;

procedure TFakeBuilderInspector.DoProcessModel(const kernel: IKernel; const
    model: TComponentModel);
begin
  kernel.Logger.Info('FakeBuilderInspector');
end;

end.

在注册中，我有

container.AddExtension<THCVLoggerExtension>;

集装箱正确调用THCVLoggerExtension.Initialize，但在我的检查员从来没有被称为DoProcessModel。为什么？
