Question

我有一个在Struts2中开发的应用程序，它部署在JBoss 7.1.1上。我们使用CDI注入依赖项。

我在Struts.xml中包含了以下内容：<constant name="struts.objectFactory.cdi.jndiKey" value="java:comp/some/weird/BeanManagerReference" />

还包括cdi-api-1.0-SP1.jar和struts2-cdi-plugin-2.3.4.1.jar罐以及应用程序的其他必需jar。

间歇性地我得到以下异常，我的服务器需要重启才能解决这个问题。

请让我知道如何解决这个问题。

问题是您在WAR文件中包含了应用服务器提供的JAR。不要包含CDI等的API jar。

使用JBoss7.1.1上的Struts2应用程序间歇性地创建CreationException
