关于Spring Boot：java.lang.ClassCastException在Wildfly 10上部署CAS 5.3.3 Maven Overlay WAR

java.lang.ClassCastException deploying CAS 5.3.3 Maven Overlay WAR on Wildfly 10

我正在使用https://apereo.github.io/cas/5.3.x/installation/Maven-Overlay-Installation.html中指定的Maven叠加层在Wildfly 10上部署CAS 5.3.3。项目模板位于：https://github.com/apereo/cas-overlay-template/tree/5.3

部署到Wildfly 10后，部署失败，但出现以下异常：

09:02:06,982 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 70) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host./cas: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./cas: java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer
at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:85)

该问题可能与Spring Boot Maven配置有关。但是，我尝试了以下解决方案，但它们不起作用：

Wildfly中的Spring Boot Websockets
WildFly 10 Spring Boot战争部署错误
org.apache.tomcat.websocket.WsWebSocketContainer无法转换为io.undertow.websockets.jsr.ServerWebSocketContainer

也可能与以下内容有关：
