typescript 에러 | Nest can't resolve dependencies of the "Service"

app.module과 프로덕트.module에서 모두 controller, service를 호출하고 있어서 충돌이 난 것

app.module에 명시된 controllers와  providers에 채워진 값들을 지우면 된다. 

 

sb.module.ts

@Module({
  imports: [TypeOrmModule.forFeature([Starbucks])],
  controllers: [SbController],
  providers: [SbController, SbService],
})
export class SbModule {}

app.module.ts (에러 발생시)

@Module({
  imports: [
    SbModule,
    ConfigModule.forRoot(),
    TypeOrmModule.forRoot({
      type: process.env.DATABASE_TYPE as 'mysql',
      host: process.env.DATABASE_HOST,
      port: Number(process.env.DATABASE_PORT),
      username: process.env.DATABASE_USERNAME,
      password: process.env.DATABASE_PASSWORD,
      database: process.env.DATABASE_DATABASE,
      entities: [Starbucks],
      synchronize: true,
      logging: true,
    }),
  ],
  controllers: [SbController],
  providers: [SbController, SbService],
})
export class AppModule {}

app.module.ts (수정 후)

@Module({
  imports: [
    SbModule,
    ConfigModule.forRoot(),
    TypeOrmModule.forRoot({
      type: process.env.DATABASE_TYPE as 'mysql',
      host: process.env.DATABASE_HOST,
      port: Number(process.env.DATABASE_PORT),
      username: process.env.DATABASE_USERNAME,
      password: process.env.DATABASE_PASSWORD,
      database: process.env.DATABASE_DATABASE,
      entities: [Starbucks],
      synchronize: true,
      logging: true,
    }),
  ],
  controllers: [],
  providers: [],
})
export class AppModule {}
