我正在尝试让 OWB（使用 MyFaces 和 Primefaces）在 Tomcat 8.0.33 上工作。似乎无论我如何配置，我都会收到此错误...

org.apache.myfaces.webapp.AbstractFacesInitializer.initFaces An error occured while initializing MyFaces: It's not allowed to call getBeans(Type, Annotation...) before AfterBeanDiscovery

...随后是此堆栈跟踪：

根据我在此处、此处和此处（以及大约 5 个其他地方）所读到的内容，我已经使用Tomcat 插件依赖项、在中指定的 OWB 侦听器web.xml，甚至两者都进行了尝试。看起来，无论我做什么，我似乎都无法说服 OWB 在 MyFaces 介入并开始做它的事情之前做它的事情。我错过了一些非常明显的东西吗？

你应该使用ContextLifecycleListener.java

将 addOwbListeners() 方法更改为以下

private void addOwbListeners(StandardContext context) {
  String[] oldListeners = context.findApplicationListeners();
  LinkedList<String> listeners = new LinkedList<String>();

  // 3rd
  listeners.addFirst("org.apache.myfaces.webapp.StartupServletContextListener");
  // 2nd
  listeners.addFirst("org.apache.webbeans.web.tomcat7.ContextLifecycleListener");
  // 1st
  listeners.addFirst("org.apache.webbeans.servlet.WebBeansConfigurationListener");

  for (String listener : oldListeners) {
    listeners.add(listener);
    context.removeApplicationListener(listener);
  }

  for (String listener : listeners) {
    context.addApplicationListener(listener);
  }
}

这个类在tomcat的通用类加载器中加载。不是 webapp 上下文类加载器。 https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

/META-INF/context.xml

<Context>
  <Listener className="mypackage.ContextLifecycleListener" />
  <Resource name="BeanManager" auth="Container"
    type="javax.enterprise.inject.spi.BeanManager"
    factory="org.apache.webbeans.container.ManagerObjectFactory" />
</Context>

I had the same problem with latest versions of the products: Tomcat 9.0.12, MyFaces 2.3.2 and OpenWebBeans 2.0.7.

According to documentation of OpenWebBeans Adding OpenWebBeans to your Servlet Container project, I added the configuration listener to web.xml

<listener>
    <listener-class>org.apache.webbeans.servlet.WebBeansConfigurationListener</listener-class>
</listener>

and this fixed the problem.

Note however, that according to the documentation adding the Tomcat7 plugin should fix the problem as well, but did not.
