使用typeorm实现typedi时ConnectionManager错误

Question

我试着和typedi一起用打字机，但有一些问题。我想对ORM使用typeorm，对GraphQL使用typegraphql，对typedi使用DI。现在，我正在尝试用typeorm实现typedi，但是我遇到了一些问题：

错误我得到了

{
  "message": "Cannot get Connection with name \"default\" from the ConnectionManager. Make sure you have created the connection and called \"useContainer(Container)\" in your application before establishing a connection and importing any entity into TypeORM.",
  "exception": {
    "connectionName": "default",
    "name": "ManagerNotFoundError",
    "stacktrace": [
      "ManagerNotFoundError: Cannot get Connection with name \"default\" from the ConnectionManager. Make sure you have created the connection and called \"useContainer(Container)\" in your application before establishing a connection and importing any entity into TypeORM."
    ]
  }
}

但是，我已经将useContainer(Container)放在连接设置之上。

src/index.ts (条目文件)

import './utils/env'
import 'reflect-metadata'
import { Server } from './server'
import { Database } from './database'
import logger from './utils/logger'
import { Container } from 'typeorm-typedi-extensions'
import { useContainer } from 'typeorm'

const server = new Server()
const database = new Database()

useContainer(Container)

void database
  .connect()
  .then(() => {
    logger.info('Database connected')
    void server.listen().then((server) => {
      const { port } = server.address() as { port: number }
      logger.info(`Server started on port ${port}`)
    })
  })
  .catch((reason) => {
    throw new Error(`Databse Error: ${reason as string}`)
  })

这是我的userRepository文件

src/entities/user/UserRepository.ts

@Service()
@EntityRepository(User)
export class UserRepository extends Repository<User> {
  // (...)
}

这是我的UserService文件

src/graphql/user/UserService.ts

@Service()
export default class UserService {
    @InjectRepository(User)
    private readonly userRepository: UserRepository

    // (...methods)
}

最后，这是我的UserResolver文件

src/graphql/user/UserResolver.ts

@Service()
@Resolver(() => User)
export class UserResolver {
  @Inject()
  private readonly userService: UserService

  (...)
}

解决:：node_modules/typeorm-typedi-extensions/cjs/container-registrations.const.js

第10行

来自

typedi_1.Container.set({ id: typeorm_1.ConnectionManager, type: typeorm_1.ConnectionManager });

到

typedi_1.Container.set({ id: typeorm_1.ConnectionManager, type: typeorm_1.ConnectionManager, global: true });
