java.lang.NullPointerException在org.omnifaces.cdi.eager.EagerBeansPhaseListener.afterPhase当两个WAR在一个EAR

Question

我在一个EAR档案中有两个基于JSF的WAR项目，这两个项目都有OmniFaces作为依赖关系，它们都将被部署。 当部署引发此错误：

如果从一个战争删除OmniFaces，部署做工精细。

Omnifaces 2.3，PrimeFaces 5.3，似鲭水狼牙鱼4.1.152

Answer 1

这是通过在CDI规范的不清晰引起的已知问题。另请参见：

• OmniFaces wiki - Known Issues (CDI)
• The BalusC Code - CDI behaved unexpectedly

我必须承认，@Eager不是在一个多模块测试耳边。这个NullPointerException是不幸的，它从来没有意图使Web应用程序不能用这种方式。最多只有OmniFaces CDI相关的功能应该无法使用，但其余应继续工作。

我在此创建了issue 290，我将根据issue 281针对当前可用的服务器重新测试多模块EAR中的所有CDI功能。

最好的办法是编辑OmniFaces JAR并从其/META-INF/faces-config.xml中删除EagerBeansPhaseListener。只有视图范围的bean的@Eager功能才会停止工作。

更新按issue 290我有固定的这个NPE。它在今天的2.5-SNAPSHOT中可用。
