问题1 org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to javax.websocket.server

严重: Servlet.service() for servlet [SpringMVC] in context with path [/ZHDM] threw exception [Request processing failed; nested exception is org.springframework.web.socket.server.HandshakeFailureException: Uncaught failure for request http://125.221.225.118:8080/ZHDM/websocket; nested exception is java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to javax.websocket.server.ServerContainer] with root cause

解决方案:

出现这个问题的原因是,apache的websocket包和javax-servlet包冲突了,找到Apache Tomcat的webApp目录,打开你部署的项目文件夹,依次打开WEB-INF/lib,找到javaee-api-7.0.jar,删除,再重新启动项目。
