Nestjs 巢罐'；t解决JWT策略的依赖关系

nestjs

Nestjs 巢罐'；t解决JWT策略的依赖关系,nestjs,typeorm,Nestjs,Typeorm,我是NestJs世界的新手。据我所知，我导入了JWT战略中所需的一切。我不知道哪里出了问题。有人能帮我吗 就我所提到的documentation而言，每当我们想要在模块中使用任何实体时，我们都应该在@module（）decorator的imports字段中导入该实体。我做到了 jwt.strategy.ts import { Injectable, UnauthorizedException } from "@nestjs/common"; import { Passport

错误如下：
考虑转到活动记录模式。您需要做的只是让您的
AbstractEntity
扩展类型化的
BaseEntity

您可以删除所有TypeForm功能导入，如：

TypeOrmModule.forFeature（[UserEntity]）
以及存储库的所有依赖项注入，如：

@InjectRepository（UserEntity）
私有userRepo：存储库
只需使用实体类进行查询：

const user=await UserEntity.findOne（{where:{username:username}}）；
根据您的错误，您的
导入
数组中有
JwtStrategy
。如果需要
JwtStrategy
，则应导入
AuthModule
，因为提供程序应仅位于
providers
数组中，而不应位于
imports
您在哪里定义了
TypeOrmModule.forRoot
？
用户
实体功能应导入到您的typeorm模块根目录中，并导入到app.module.ts中。它以前是有用的。但现在没有了？我将更新app.module.ts。好的，我可以看到您的问题谢谢@yash。我会等你的回答。好的，谢谢你。我会努力实现它。我一定会试试@yash。谢谢你的回答。
