我正在使用Java 8 / Tomcat 8 / OpenWebBeans 1.5.0 / MyFaces 2.2.8 / DeltaSpike 1.3.0。
当我想使用openwebbeans-tomcat7模块时，我将以下jar放在了tomcat / lib中：
我也喜欢使用很棒的omnifaces库。因此，在WEB-INF / lib中，我的webapp具有无所不包的依赖性
我使用的两个版本1.8.1和2.0的CDI出现问题。在我看来，全能面是在openwebbeans之前启动的，因此找不到CDI。
在1.8.1中，此问题引发了一个异常，但它是非阻塞的，因为CDI在此版本中不是必需的。在2.0中，它阻止Web应用程序启动，因为omnifaces 2.0具有CDI要求。
在1.8.1中，日志为：

该问题仅出现在多功能界面上。OWB可在我的webapp中使用。
根据容器的不同，启动顺序仍然非常困难（例如，请参见http://javaeesquad.blogspot.fr/2015/03/getting- notified-when-java-ee.html）。
我看到OmniFaces已经处理了Glassfish特例：
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.

在课堂上Hacks：
// 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是否可能有这种特殊情况？测试设置属性对我来说是足够公平的。
还是有可能推迟全方位的实例化？
最后，为什么不使用以下方法等待CDI通知：
public class CDIStartup { public void postConstruct(@Observes @Initialized(ApplicationScoped.class) Object o) { // CDI Ready } }
OmniFaces需要更改校验码，因为它不可携带。CDI规范没有定义BeanManager或任何上下文都必须在ServletContainerInitializer中可用。这在很大程度上取决于目标环境和集成方案，因此高度不可移植。与可以正常使用的旧版本相比，这也是一种回归。
将其移动到ServletContextListener，或使其成为警告并完成。
