错误

RepositoryNotFoundError：找不到“UserQueryRepository”的存储库。看起来这个实体没有在当前的“默认”连接中注册？

版本

  • @nestjs/typeorm - 7.1.5
  • @nestjs/common - 7.6.15
  • @nestjs/核心 - 7.6.15
  • 节点 - 12.21.0
  • typeorm - 0.2.34

问题描述

我有 2 个项目：common & microservice-1

通用包有 QueryService 和 QueryRepository 并且 microservice-1 应该从这些文件扩展。

所以在微服务 1 中，我有从 QueryService 扩展的 UserQueryService 和从 QueryRepository 扩展的 UserQueryRepository。

查询.repository.ts

import { FindManyOptions, Repository } from 'typeorm';

export class QueryRepository<Entity> extends Repository<Entity> {
  findAll(options?: FindManyOptions<Entity>): Promise<Entity[]> {
    return this.find(options);
  }
}

查询.service.ts

import { FindManyOptions } from 'typeorm';
import { QueryRepository } from '../repository';

export class QueryService<Entity> {
  constructor(protected readonly repository: QueryRepository<Entity>) {}

  findById(id: string): Promise<Entity> {
    return this.repository.findOne(id);
  }

  findAll(options?: FindManyOptions<Entity>): Promise<Entity[]> {
    return this.repository.findAll(options);
  }
}

user.query.repository.ts

import { QueryRepository } from '@project/common';
import { EntityRepository, Repository } from 'typeorm';
import { UserEntity } from '../entity';

@EntityRepository(UserEntity)
export class UserQueryRepository
  extends QueryRepository<UserEntity> { // -> throws error
  // extends Repository<UserEntity> { // -> works without extending from common
}

user.query.service.ts

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { QueryService } from '@project/common';
import { UserEntity } from '../entity';
import { UserQueryRepository } from '../repository';

@Injectable()
export class UserQueryService extends QueryService<UserEntity> {
  constructor(
    @InjectRepository(UserQueryRepository)
    repository: UserQueryRepository,
  ) {
    super(repository);
  }

  getAllUsers(): Promise<UserEntity[]> {
    return this.findAll();
  }
}

用户模块.ts

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { UserController } from '../controller';
import { UserQueryRepository } from '../repository';
import { UserQueryService } from '../service';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'postgres',
      host: 'localhost',
      port: 5432,
      username: 'user',
      password: 'pass',
      database: 'dbname',
      autoLoadEntities: true,
      synchronize: true,
    }),
    TypeOrmModule.forFeature([UserQueryRepository]),
  ],
  controllers: [UserController],
  providers: [UserQueryService],
})
export class UserModule {}
