我正在尝试在 Wildfly 11 中（从 Eclipse 中）部署基于 vaadin CDI 的战争，但出现以下错误：

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 beans.xml 文件。有人知道我缺少什么吗？

【解决方案1】：

您的 CDI api 应在“提供”范围内，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 引导您的项目，然后您就可以从头开始。

【解决方案2】：

您还记得从您的主 UI 类中删除 VaadinServlet 吗？
