【中文标题】java.lang.ClassCastException 在 Wildfly 10 上部署 CAS 5.3.3 Maven Overlay WAR【英文标题】：java.lang.ClassCastException deploying CAS 5.3.3 Maven Overlay WAR on Wildfly 10 【发布时间】：2019-02-23 07:23:41 【问题描述】：

我正在 Wildfly 10 上部署 CAS 5.3.3，使用 https://apereo.github.io/cas/5.3.x/installation/Maven-Overlay-Installation.html 中指定的 Maven Overlay 并使用位于 https://github.com/apereo/cas-overlay-template/tree/5.3 的项目模板

部署到 Wildfly 10 后，部署失败并出现以下异常：

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)

问题可能与 Spring Boot Maven 配置有关。但是，我尝试了这些解决方案，但它们不起作用：

Spring Boot Websockets in Wildfly WildFly 10 Spring Boot war Deployment Error org.apache.tomcat.websocket.WsWebSocketContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer

也可能与：

【问题讨论】：

你能提供你的pom.xml吗？您是否已将元素 <app.server>-tomcat</app.server> 替换为 <app.server></app.server>？您没有在 tomcat 上部署 cas，因此这些元素不应存在。谢谢，这是我尝试的第一件事，我取消了 app.server。我已经编辑了添加 pom.xml 的问题我仍然可以在您的 pom <app.server>-tomcat</app.server> properties 条目下看到。请问也可以去掉吗？如果你已经完成了，请忽略我的评论。最后一件事。如果您还没有尝试过this thread 中提出的解决方法。再次感谢，我尝试了这种解决方法，结果相同，异常相同。 【参考方案1】：

终于解决了。

CAS War 覆盖正在加载两个 jar，我无法排除将它们的依赖项标记为已提供。问题是这些 jars 来自 CAS 覆盖，它被复制到生成的战争的 WEB-INF/lib 中。

tomcat-embed-websocket-*.jar -> java.lang.ClassCastException WEB-INF/lib/log4j-slf4j-*.jar -> 记录相关异常

所以我使用排除将它们从生成的 jar 中排除。

这是最终的 POM，可以在 Wildfly 上正确部署：
