Question

我试图在wildfly 11（来自eclipse中）部署基于vaadin CDI的战争，但我有以下错误：

21:14:36,578 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host."/myapp-1.0-SNAPSHOT".UndertowDeploymentInfoService: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host."/myapp-1.0-SNAPSHOT".UndertowDeploymentInfoService: java.lang.ClassNotFoundException: com.vaadin.cdi.internal.VaadinCDIServlet from [Module "deployment.myapp-1.0-SNAPSHOT.war" from Service Module Loader]

获得VaadinCDIServlet课程似乎有问题。这些是我在pom.xml中的依赖项

我在WEB-INF下有一个空的beans.xml文件。任何人都知道我错过了什么？

Answer 1

你的CDI api应该在＆＃34;提供＆＃34;范围，将其置于默认范围内可能会导致奇怪的问题。

我建议使用the Viritin CDI archetype启动您的项目，然后从一开始就获得所有内容。

Answer 2

您是否记得从主UI类中删除VaadinServlet？
