一、该问题的重现步骤是什么？

1. 启动项目，能成功注册到Nacos上，访问系统也是正常的，控制台一直重复打印空指针，user服务也是一直打印 NotNo mapping for GET /,也没有其他地方有调用的，控制台一直打印

2. 

3.


二、你期待的结果是什么？实际看到的又是什么？

控制台不报错


三、你正在使用的是什么产品，什么版本？在什么操作系统上？

BladeX 2.8.1 


四、请提供详细的错误堆栈信息，这很重要。


五、若有更多详细信息，请在下面提供。

GateWay控制台：

    是不是前端有一个地方或者其他的调用工具在重复访问网关所在的这个地址ip。只有这种情况才会有这个提示。你可以试着把网管的端口改掉，改成其他的，看看还有没有这个提示。

    如果没有的话就说明是外部有一个地方一直在调用，需要去排查一下
