java.lang.ClassCastException部署CASC5.3.3Maven覆盖战争在野生蝇10上

Question

我正在野生蝇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覆盖，并使用项目模板at：https://github.com/apereo/cas-overlay-template/tree/5.3

部署到Wildfly 10之后，除以下例外情况外，部署将失败：

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)

这个问题可能与Spring配置有关。然而，我尝试过这些解决方案，但它们没有奏效：

• 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

这也可能与以下方面有关：

Answer 1

最后，我解决了它。

CAS War覆盖正在加载两个War，我不能排除按照提供的方式标记它们的依赖项。问题是这些war来自CAS覆盖，它被复制到war的WEB/lib中。

• tomcat-embed websocket-*..jar -> java.lang.ClassCastException
• WEB/lib/log4j-slf4j-*..jar与->日志记录相关的异常

因此，我将它们排除在生成的jar中，使用的是“排除”。
