java - Wildfly - 10.x - WELD-001414 : Bean name is ambiguous. 名称 csfFLOWDISCOVERYCDIHELPER 解析为 beans

Question

• 服务器 - WildFly - 10.1.0
• JSF 版本 - 2.2
• Primefaces - 5.0

我正在尝试在 WildFly 10.1.0 服务器中部署 .war 文件。早些时候，我在 JBoss 7.1 上运行它，并且运行良好。但现在，当我尝试在 WildFly 服务器中部署应用程序时，遇到了一组导致部署失败的异常。

我并没有真正明白这个异常所指向的地方。错误也不清楚。我发现了其他关于此错误的 SO 帖子，但这些帖子是与 GlassFish 服务器有关的。有没有人遇到过类似类型的问题并解决了这个问题。如果有人指出我正确的方向或有任何解决方案，我将非常感激。

Answer 1

应用程序中的 jsf-api 和 jsf-impl jar 版本与应用程序服务器实现的版本不同会导致此问题。从 WEB-INF/lib 文件夹中删除应用程序提供的 jar 并使用服务器提供的 jar 可以解决问题。
