nestjs创建基本crud服务

创建基本CRUD服务,如下所示:

export class BaseCrudService<Entity extends BaseEntity> {

    constructor(
        public repository: Repository<Entity>,
    ) { }

    async insertAsync(entity: Entity): Promise<InsertResult> {
        return this.repository.insert(entity);
    }
    ...
}

@Injectable()
export class UserService extends BaseCrudService<UserEntity>{
  constructor(
    @InjectRepository(UserEntity)
    public repository: Repository<UserEntity>,
  ) {
    super(repository);
  }
}

现在,您已经完成了插入、删除、更新等工作。这适用于扩展类的所有服务。
