将依赖项注入具有tsyringe的控制器时出错

Question

我使用express和tsyringe进行依赖注入。

当我尝试在控制器上使用服务依赖项时，我会收到一个错误未处理的PromiseRejectionWarning:TypeError:无法读取文件addressController.ts 中未定义的属性"addressService">

我搜索了几个视频和文章，但找不到解决它们的方法。我会把我的代码留在下面

addressRepository.ts

import { AddressResponseDTO } from '../../dtos/response/address/addressResponseDTO';
export interface IAddressRepository {
getAddresses(): Array<AddressResponseDTO>;
}

addressRepositoryImpl.ts

import { AddressResponseDTO } from '../../dtos/response/address/addressResponseDTO';
import { IAddressRepository } from '../declarations/addressRepository';
export default class AddressRepositoryImpl implements IAddressRepository {
getAddresses(): Array<AddressResponseDTO> {
const address1: AddressResponseDTO = {
id: 'ADR123',
postalCode: '17014273',
address: 'Rua José Aiello',
district: 'Centro',
number: '347',
city: 'Bauru',
state: 'São Paulo',
phoneNumber: '16997102842',
clientName: 'João Mário Marcelo Campos',
};
const address2: AddressResponseDTO = {
id: 'ADR456',
postalCode: '07135290',
address: 'Rua Mariano Moya Peramos',
district: 'Jardim Adriana',
number: '1103',
city: 'Guarulhos',
state: 'São Paulo',
phoneNumber: '16997102842',
clientName: 'João Mário Marcelo Campos',
};
return [address1, address2];
}
}

addressService.ts

import { AddressResponseDTO } from '../../dtos/response/address/addressResponseDTO';
import ResultResponseDTO from '../../dtos/response/resultResponseDTO';
export interface IAddressService {
getAddresses(): ResultResponseDTO<Array<AddressResponseDTO>>;
}

addressServiceImpl.ts

import { StatusCodes } from 'http-status-codes';
import { inject, injectable } from 'tsyringe';
import logger from '../../configurations/logger';
import { AddressResponseDTO } from '../../dtos/response/address/addressResponseDTO';
import ResultResponseDTO from '../../dtos/response/resultResponseDTO';
import { IAddressRepository } from '../../repositories/declarations/addressRepository';
import { IAddressService } from '../declarations/addressService';
@injectable()
export default class AddressServiceImpl implements IAddressService {
private addressRepository: IAddressRepository;
constructor(@inject('AddressRepository') addressRepository: IAddressRepository) {
this.addressRepository = addressRepository;
}
getAddresses(): ResultResponseDTO<AddressResponseDTO[]> {
try {
logger.info('AddressService.getAddresses - start');
const addresses = this.addressRepository.getAddresses();
logger.info('AddressService.getAddresses - end');
return ResultResponseDTO.ok(StatusCodes.OK, '', addresses);
} catch (error) {
logger.error(`AddressService.getAddresses - error - message ${error}`);
return ResultResponseDTO.fail(
StatusCodes.INTERNAL_SERVER_ERROR,
'Error getting addresses',
error,
);
}
}
}

addressController.ts

第行出现错误：const result=this.addressService.getAddresses()

import { Request, Response } from 'express';
import { inject, injectable } from 'tsyringe';
import { IAddressService } from '../services/declarations/addressService';
@injectable()
export class AddressController {
constructor(@inject('AddressService') private addressService: IAddressService) {}
public async getAddresses(request: Request, response: Response): Promise<Response> {
const result = this.addressService.getAddresses();
return response.status(result.httpStatus).json(result.getResponse());
}
}

路线.ts

import { Router } from 'express';
import { container } from 'tsyringe';
import { AddressController } from './controllers/addressController';
import AddressRepositoryImpl from './repositories/implementations/addressRepositoryImpl';
import AddressServiceImpl from './services/implementations/addressServiceImpl';
const routes = Router();
container
.register('AddressRepository', {
useClass: AddressRepositoryImpl,
})
.resolve(AddressRepositoryImpl);
container
.register('AddressService', {
useClass: AddressServiceImpl,
})
.resolve(AddressServiceImpl);
const addressController = container.resolve(AddressController);
routes.get('/', (request, response) => {
response.send('It works!');
});
// AddressController
routes.route('/v1/address').get(addressController.getAddresses);
export default routes;

Answer 1

您将IoC内部的服务注册为"AddressServiceImpl"，然后尝试将其调用为"AddressService"。

// service file
@injectable()
export default class AddressServiceImpl implements IAddressService {

// controller file
@injectable()
export class AddressController {
constructor(@inject('AddressService') private addressService: IAddressService) {}
