omnifaces 在 openwebbeans 1.5.0 之前开始？
omnifaces starting before openwebbeans 1.5.0?
我正在使用 Java 8 / Tomcat 8 / OpenWebBeans 1.5.0 / MyFaces 2.2.8 / DeltaSpike 1.3.0。
因为我想使用 openwebbeans-tomcat7 模块，所以我将以下 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
- 我的脸-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
我也喜欢使用很棒的 omnifaces 库。因此，我的 webapp 在 WEB-INF/lib
中具有 omnifaces 作为依赖项
我使用的两个版本 1.8.1 和 2.0 的 CDI 存在问题。
在我看来，omnifaces 在 openwebbeans 之前启动，因此找不到 CDI。
在 1.8.1 中，这个问题引发了一个异常，但它是非阻塞的，因为 CDI 在这个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 有 CDI 作为要求。
对于 1.8.1，日志是：

只有 omnifaces 才会出现此问题。 OWB 在我的网络应用程序中工作。
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 已经处理了 Glassfish 的特殊情况：
public class 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(""

并在 class 技巧中：
// GlassFish related ----------------------------------------------------------------------------------------------
/**

* @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 可以有这样的特例吗？
测试是否设置了属性对我来说足够公平了。
或者是否可以推迟 omnifaces 实例化？
最后，为什么不等待CDI通知，方法如：
public class CDIStartup {
public void postConstruct(@Observes @Initialized(ApplicationScoped.class) Object o) {
// CDI Ready }
}
OmniFaces 需要更改检查代码，因为它是不可移植的。 CDI 规范没有定义 BeanManager 或任何上下文需要在 ServletContainerInitializer 中可用。这在很大程度上取决于目标环境和集成场景，因此非常不可移植。
与它完美运行的旧版本相比，这也是一种倒退。
将其移至 ServletContextListener，或将其设为警告并完成。

只有 omnifaces 才会出现此问题。 OWB 在我的网络应用程序中工作。
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 已经处理了 Glassfish 的特殊情况：
public class 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(""
+ "\n████████████████████████████████████████████████████████████████████████████████"
+ "\n▌ ▐█ ▐ ▐"

并在 class 技巧中：
// 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 可以有这样的特例吗？ 测试是否设置了属性对我来说足够公平了。
或者是否可以推迟 omnifaces 实例化？
最后，为什么不等待CDI通知，方法如：
public class CDIStartup {
public void postConstruct(@Observes @Initialized(ApplicationScoped.class) Object o) {
// CDI Ready }
}
OmniFaces 需要更改检查代码，因为它是不可移植的。 CDI 规范没有定义 BeanManager 或任何上下文需要在 ServletContainerInitializer 中可用。这在很大程度上取决于目标环境和集成场景，因此非常不可移植。 与它完美运行的旧版本相比，这也是一种倒退。
将其移至 ServletContextListener，或将其设为警告并完成。
