springboot2.0使用WebSocket 添加@Component启动报错

Question

请教各位大佬：
springboot2.0使用WebSocket 添加@Component启动报错
使用springboot内置tomcat （Apache Tomcat/9.0.13）
下面是报错信息：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

不知道你问题解决了没有，可能有其他人会翻到，我试着回答一下吧：
首先参考了以下链接：http://www.pianshen.com/article/721751997/ ，了解到这个报错是因为websocket被代理了，像这个链接中的原因是切面，但是我的情况是没有用切面处理它，然后发现我的websocket实现类放的文件夹是service，联想到框架这种东西，在启动的时候做很多的初始化，可能是把这个类在启动的时候被当成了框架的业务层做了代理，所以我另外建了一个叫websocket的文件夹，把这个类往里面一丢就启动成功了。
