Answer 1

JandexAnnotationProvider实际上从AnnotationProvider类扩展，如果两个类都是通过不同的类加载器加载的，则可能会导致此类错误。

我认为您必须从您的应用程序中排除jsf-api-???.jar和jsf-impl-???.jar。使用应用程序服务器提供的jsf库。

要使用maven实现它，只需将<scope>provided</scope>设置为jsf-api

中的jsf-impl和pom.xml依赖项

javax.faces.FacesException：类org.jboss.as.jsf.injection.JandexAnnotationProvider不是com.sun.faces.spi.AnnotationProvider的实例
