如何正确地连接控制器和接口？

我无法实现接口的方法，我得到错误ReferenceError: INew is not defined

我有以下文件：

• /services/newService.ts
• /controllers/NewController.ts
• /interfaces/INew.ts
• /repositories/NewRepository.ts

1个新的服务

 import express = require("express"); import NewController = require("../controllers/NewController"); var router = express.Router(); class NewRoutes { private _newController: NewController; constructor () { this._newController = new NewController(); } get routes () { var controller = this._newController; router.get("/new", controller.retrieve); return router; } } Object.seal(NewRoutes); export = NewRoutes; 

2控制器

 import INew = require("../interfaces/INew"); class NewController{ private _INew: INew; constructor(){ this._INew = new INew(); // !!!! INew became RED --> cannot find name 'INew' } retrieve(req: express.Request, res: express.Response): void { try { console.log('--------------NewController-----------------'); this._INew.findById(2); } catch (e) { console.log(e); } } } Object.seal(NewController); export = NewController; 

3新

 interface INew { findById: (id: number) => void; } export = INew; 

4 NewRepository

 import INew = require("../interfaces/INew"); class NewRepository implements INew { constructor() { } findById(id) { console.log('RESULT'); } } Object.seal(NewRepository); export = NewRepository; 

当我尝试构build应用程序时，出现错误：

  this._INew = new INew(); ^ ReferenceError: INew is not defined 

请帮助
