WildFly 10 Spring Boot war Deployment Error

问题

I cannot upload and deploy my Spring Boot WAR package application on WildFly 10 because of the following error:

Cannot upload deployment: {"WFLYCTL0080: Failed services" => {"jboss.undertow.deployment.default-server.default-host./NetonePrepaidBillingRestService" => "org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./NetonePrepaidBillingRestService: java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer Caused by: java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer Caused by: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer"},"WFLYCTL0412: Required services that are not installed:" => ["jboss.undertow.deployment.default-server.default-host./NetonePrepaidBillingRestService"],"WFLYCTL0180: Services with missing/unavailable dependencies" => undefined}

You should remove the dependency of spring-boot-starter-undertow if you want to deploy your WAR file to any Servlet 3 container.

Please also refer to this article What about the Java EE Application Server? on Spring official website.
