通过mongoose nestjs中的属性获取用户的正确方法

import * as mongoose from 'mongoose';

export const UserSchema = new mongoose.Schema({
  name: String,
  age: Number,
  email: String,
});

import { Injectable } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { User } from './interfaces/user.interface';

@Injectable()
export class UserService {
  constructor(@InjectModel('User') private readonly userModel: Model<User>) {}

  async getUserById(id: string): Promise<User> {
    return this.userModel.findById(id).exec();
  }
}

async getUserInfo(id: string): Promise<User> {
  const user = await this.userService.getUserById(id);
  return user;
}
