Nestjs类型安全mongoose，模型函数不要求正确的类型(any)

npm install mongoose @nestjs/mongoose

import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';

@Module({
  imports: [
    MongooseModule.forRoot('mongodb://localhost:27017/mydatabase'),
  ],
})
export class AppModule {}

import { Schema, Prop, SchemaFactory } from '@nestjs/mongoose';
import { Document } from 'mongoose';

@Schema()
export class User extends Document {
  @Prop()
  name: string;

  @Prop()
  age: number;
}

export const UserSchema = SchemaFactory.createForClass(User);

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

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

  async createUser(name: string, age: number): Promise<User> {
    const user = new this.userModel({ name, age });
    return user.save();
  }

  async getUsers(): Promise<User[]> {
    return this.userModel.find().exec();
  }
}
