我正在使用express.js和typeorm。我想创建BookRepository，它将是扩展typeorm仓库的自定义仓库。

import { Repository } from 'typeorm';
import { AppDataSource } from '..';
import { provideSingleton } from '../common/utils/ProvideSingleton';
import { Book } from './Book';

@provideSingleton(BookRepository)
export class BookRepository extends Repository<Book> {
    constructor() {
        super(Book, AppDataSource.manager, AppDataSource.createQueryRunner());
    }
}

但当我点击激活控制器-〉服务-〉存储库的路径时，我得到以下错误：

Error: The number of constructor arguments in the derived class BookRepository must be >= than the number of constructor arguments of its base class.

不确定我做错了什么，因为typeorm Repository类有3个参数，最后一个是可选的：

constructor(target: EntityTarget<Entity>, manager: EntityManager, queryRunner?: QueryRunner);
