springboot2.0使用WebSocket 添加@Component启动报错

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。
