我关注的问题。出于某些原因，我在一个EAR内的两个不同的WAR模块中有一个jar的副本。不幸的是，通过CDI引入注入失败，因为类加载器检测到两个实现，并且它不知道应该使用哪个实现。有一个错误是这样的：

OcmInitFacesContextFactory通过@Inject注释注入SessionObserver
确定它是由重复引起的，因为如果没有复制的jar，它就能正常工作。
我的问题不在于，有没有办法告诉CDI（Weld）仅在一个WAR模块中搜索依赖项？我试图将它排除在扫描之外（在这个jar文件中的beans.xml中），但这不是重点，因为它根本不会注入它们。目前我无法更改此EAR和WAR文件的设计。
