当启动Wildfly时，我得到以下警告:
WELD-000411: Observer method [backdannotatedmethod] public org.omnifaces.VetoAnnotatedTypeExtension。processAnnotatedType(@ observectprocessannotatedtype)接收所有注释类型的事件。考虑使用@WithAnnotations或带边界的泛型类型来限制事件。
你知道是什么原因造成的吗?下面是启动日志:

默认情况下，支持CDI的容器尝试将/WEB-INF/lib中的jar中的每个类注册为CDI管理的bean。在旧的Java EE 6容器使用的旧CDI版本中，存在一些bug，其中CDI实现甚至试图注册枚举、抽象类和/或没有默认构造函数的类，从而导致部署异常(WebLogic)、运行时异常(WebSphere)和/或大量令人困惑的警告(GlassFish/TomEE)。
为了解决这个问题，OmniFaces添加了一个VetoAnnotatedTypeExtension，它应该"否决"org.omnifaces包中的任何类，这些类在org.omnifaces.cdi或org.omnifaces.showcase子包中不是，不能被注册为CDI管理bean。这通过ProcessAnnotatedType#veto()实现。
In Weld 2。在WildFly中使用的x，显然有一种新的警告类型，当您在所有类上使用ProcessAnnotatedType时会发生。然而，在这个特定的情况下，扫描每个单独的类只是整个目的，因为需要排除被注册为CDI托管bean的类显然没有显式地注册为CDI托管bean(对此，您可以使用更具体的T或@WithAnnotations，如警告消息中所建议的)。
理论上，在这种特殊情况下的解决方案是在beans.xml中使用<weld:include>或<weld:exclude>而不是Extension。然而，这不是一个标准的CDI解决方案，因为这是特定于weld的，因此不能与其他CDI实现(如OpenWebBeans或CanDI)一起工作。我们无法为其他CDI实现找到类似的机制，所以我们选择了Extension。毕竟，这"只是"一个警告，而不是一个错误。
