In order to get DI working, you have to provide Injectable. about node-decorators HOT 5 CLOSED

import UserDao, {UserInter} from '../dao/UserDao'
import {Injectable} from '@decorators/di'

@Injectable()
export default class UserService {
  constructor(private userDao: UserDao) {
  }
  
  register(user: UserInter) {
    const registerRs = this.userDao.register(user)
  }
}

import {getRepository} from 'typeorm'
import UserInfo from '../entities/UserInfo'
import UserAccount from '../entities/UserAccount'

export interface UserInter {
  username: string
  password: string
  email: string
  active: boolean
}


export default class UserDao {
  // 用户注册
  // TODO 事务处理
  async register(user: UserInter) {
    const userAccountRep = getRepository(UserAccount)
    const userInfoRep = getRepository(UserInfo)
    const userAccountRs = await userAccountRep.save(user)
    
    const userInfo: any = {
      username: user.username,
      sex: true,
      location: '北京市',
      birth: '1970-01-01',
      avatar: 'http://placehold.it/100x100'
    }
    const userInfoRs = await userInfoRep.save(userInfo)
    return {
      userAccountRs, userInfoRs
    }
  }
}
