【问题描述】：
我正在使用 Java 8 / Tomcat 8 / OpenWebBeans 1.5.0 / MyFaces 2.2.8 / DeltaSpike 1.3.0。
由于我想使用 openwebbeans-tomcat7 模块，我将以下 jar 放在 tomcat/lib 中：
- openwebbeans-web-1.5.0.jar
- openwebbeans-tomcat7-1.5.0.jar
- openwebbeans-spi-1.5.0.jar
- openwebbeans-resource-1.5.0.jar
- openwebbeans-jsf-1.5.0.jar
- openwebbeans-impl-1.5.0.jar
- openwebbeans-el22-1.5.0.jar
- xbean-finder-shaded-4.1.jar
- xbean-asm5-shaded-4.1.jar
- myfaces-impl-2.2.8.jar
- myfaces-api-2.2.8.jar
- geronimo-atinject_1.0_spec-1.0.jar
- geronimo-annotation_1.2_spec-1.0.jar
- geronimo-validation_1.0_spec-1.1.jar
- geronimo-stax-api_1.0_spec-1.0.jar
- geronimo-servlet_3.0_spec-1.0.jar
- geronimo-jcdi_1.1_spec-1.0.jar
- geronimo-interceptor_1.2_spec-1.0.jar
- commons-digester-1.8.jar
- commons-beanutils-1.8.3.jar
- commons-collections-3.2.jar
- commons-logging-1.1.1.jar
- commons-codec-1.3.jar
我也喜欢使用伟大的 omnifaces 库。因此，我的 webapp 在 WEB-INF/lib 中具有omnifaces 作为依赖项
在我使用的两个版本（1.8.1 和 2.0）中，CDI 存在问题。 在我看来，omnifaces 是在 openwebbeans 之前启动的，因此找不到 CDI。
在 1.8.1 中，此问题会引发异常，但它是非阻塞的，因为 CDI 在此版本中不是强制性的。在 2.0 中，它会阻止 webapp 启动，因为 omnifaces 2.0 需要 CDI。
在 1.8.1 中，日志为：

这个问题只发生在全向。 OWB 在我的 web 应用中工作。
启动顺序仍然非常不稳定，具体取决于容器（例如参见http://javaeesquad.blogspot.fr/2015/03/getting-notified-when-java-ee.html）。
我看到 OmniFaces 已经处理 Glassfish 特殊情况：
公共类 ApplicationInitializer 实现 ServletContainerInitializer {
// Constants ------------------------------------------------------------------------------------------------------
private static final Logger logger = Logger.getLogger(ApplicationInitializer.class.getName());
// Actions --------------------------------------------------------------------------------------------------------
@Override
public void onStartup(Set<Class<?>> c, ServletContext servletContext) throws ServletException {
logOmniFacesVersion();
checkCDIAvailable(servletContext);
FacesViews.registerFilter(servletContext);
}
private void logOmniFacesVersion() {
logger.info("Using OmniFaces version " + getClass().getPackage().getSpecificationVersion());
}
private void checkCDIAvailable(ServletContext servletContext) throws ServletException {
if (Hacks.isCDIAvailableInGlassFish(servletContext)) {
return; // Okay. Don't proceed, because GF4 fails to scan JNDI during servlet container initialization.
}
try {
BeanManager.INSTANCE.toString();
}
catch (Throwable e) {
logger.severe(""

在课堂上的黑客：
// GlassFish related ----------------------------------------------------------------------------------------------
/**
* Returns <code>true</code> if CDI is available in GlassFish.
* @param servletContext The involved servlet context.
* @return <code>true</code> if CDI is available in GlassFish.
*/
public static boolean isCDIAvailableInGlassFish(ServletContext servletContext) {
return servletContext.getAttribute("org.glassfish.jsp.beanManagerELResolver") instanceof ELResolver;
}
OWB 有可能有这样的特殊情况吗？ 测试设置属性对我来说足够公平。
或者是否可以推迟全脸实例化？
最后，为什么不等待CDI通知呢，方法如下：
public class CDIStartup {
public void postConstruct(@Observes @Initialized(ApplicationScoped.class) Object o) {
// CDI Ready }
}
【问题讨论】：
-
我们以前见过这种情况。在普通 Tomcat 中正确集成 OWB 很麻烦。这就是TomEE存在的原因。它在那里完美地工作。如果您真的需要 Tomcat，请考虑使用 Weld。与此同时，我们将思考如何很好地解决这个问题。 CDI 扩展不适合，因为它需要 CDI。
-
我理解您的回复，无论如何感谢您为我们提供全方位信息。显然很难完全支持所有容器。但是在某些地方，你不能选择你的容器。不久前，我无法将 jars 放入 tomcat/lib 中......所以......我不明白你的最后一句话“CDI 扩展不适合，因为它需要 CDI”。在我看来，由 CDI 启动它可以确保最后一个可用...当然，这仅适用于 2.0。
-
> “在普通 Tomcat 中正确集成 OWB 很麻烦”。抱歉 Bauke @BalusC，这完全错了！ OpenWebBeans 只提供了 2 种不同的集成方式。一种简单的“Servlet”方式，即使在 GAE 和其他非 EE 容器中也可移植。然后是完整的 EE 集成方式。关键是您完全用 Omnifaces-2.0 破坏了所有标准 Servlet 集成用例！返回并再次删除该检查并感到高兴。
-
看我对你的回答的评论，struberg。
-
所以，如果我理解你的对话框，你可以编写一个扩展，这是一个实现 javax.enterprise.inject.spi.Extension 并观察 BeforeBeanDiscovery 事件的类（而不是 @Initialized(ApplicationScoped .class）我建议）？我很乐意帮助测试。 ;-)
