org.apache.tomcat.websocket.server.WsSci cannot be cast to javax.servlet.Servlet

Question

web工程依赖一个SpringBoot工程，web工程为Tomcat插件启动
web工程启动的时候每次报下面三个错误中的一个。
1.org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet
2.org.apache.tomcat.websocket.server.WsSci cannot be cast to javax.servlet.Servlet
3.ch.qos.logback.classic.servlet.LogbackServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer
两个工程的pom依赖如下，
