在wildfly中部署vaadin servlet (使用vaadin CDI)时出错

Question

我试图在wildfly 11中(在eclipse中)部署一个基于vaadin CDI的war，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]

获取VaadinCDIServlet类似乎有问题。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。有人知道我错过了什么吗？

Answer 1

您的CDI api应该在"provided“作用域中，让它在默认作用域中可能会导致奇怪的问题。

我建议用the Viritin CDI archetype引导你的项目，然后你就可以从一开始就做好所有的事情。

Answer 2

您是否记得从主UI类中删除VaadinServlet？
