部署时 java.lang.IllegalStateException: Failed to register @ServerEndpoint class:

Tomcat 日志如下:

2020-03-28 16:32:08,187 -Initializing ExecutorService 'applicationTaskExecutor'

注意到下面一句，明显是重复注入了

Caused by: javax.websocket.DeploymentException: Multiple Endpoints may not be deployed to the same path [/ws/init] : existing endpoint was class net.unwi.ulog.domain.WebsocketServer and new endpoint is class net.unwi.ulog.domain.WebsocketServer

翻了几页博客都是参照

或者把 @Component 注解去掉。

但是服务器可以本机调试又404了，总不能打包一次改一次是吧！

这么一来，要么本机用额外的tomcat调试，要么...

最后我选择用上述文章中的第二种方法重做的模块，既然选择了springboot，就跟随他到死吧。
