如何监听在Nestjs中有注入服务的监听器的事件？

@Injectable()
export class MyService {
  // 服务的逻辑代码
}

@Injectable()
export class MyService {
  @EventEmitter()
  myEvent: EventEmitter<string>;
  
  // 服务的逻辑代码
}

@Injectable()
export class MyService {
  @EventEmitter()
  myEvent: EventEmitter<string>;
  
  triggerEvent() {
    this.myEvent.emit('Event triggered!');
  }
  
  // 服务的逻辑代码
}

@Injectable()
export class MyListener {
  constructor(private readonly myService: MyService) {}
  
  @OnEvent('myEvent')
  handleMyEvent(eventData: string) {
    // 处理事件的逻辑代码
    console.log(eventData);
  }
}

@Module({
  providers: [MyService, MyListener],
})
export class AppModule {}
