如何在CustomRepository(nestjs)中使用DI

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { CustomEntity } from './custom.entity';

@Injectable()
export class CustomRepository {
  constructor(
    @InjectRepository(CustomEntity)
    private readonly customRepository: Repository<CustomEntity>,
  ) {}
}

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { CustomRepository } from './custom.repository';
import { CustomEntity } from './custom.entity';

@Module({
  imports: [TypeOrmModule.forFeature([CustomEntity])],
  providers: [CustomRepository],
})
export class CustomModule {}

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { CustomEntity } from './custom.entity';

@Injectable()
export class CustomRepository {
  constructor(
    @InjectRepository(CustomEntity)
    private readonly customRepository: Repository<CustomEntity>,
  ) {}

  async findCustomById(id: number): Promise<CustomEntity> {
    return this.customRepository.findOne(id);
  }
}
