我有一个场景，我们在JBoss4.2.3上部署了两个EAR。每个Ear都有自己定义的applicationContext。但我意识到在调试时，一个应用程序bean定义会覆盖另一个。
这是服务器日志：

我在这方面挣扎了好几天，但我找不到解决办法。如果有人以前经历过这个问题，请帮助我。
答案 0 :(得分：1)
但是我在调试时意识到，一个应用程序bean定义覆盖了另一个。
不确定在调试时看到了什么，但根据您提供的日志，您有两个单独的BeanFactories：
DefaultListableBeanFactory @ 8478d0，它结合了来自
的bean定义DefaultListableBeanFactory @ 1632823，它结合了来自
的bean定义我假设你有两个网络应用程序（每个耳朵一个），它们都设置应用程序上下文。
你的问题似乎与第二个背景有关：
ApplicationContextProvider（bean名称applicationContextProvider）同时定义：SecureClaim.ear/SipsFacelet.jar!/META-INF/applicationContext.xml和/WEB-INF/applicationContext.xml ActiveMQConnectionFactory（bean名称brokerIp）同时定义：IDP.ear/IDPEJB.jar!/META-INF/applicationContext.xml和SecureClaim.ear/SipsMessaging.jar!/META-INF/applicationContext.xml RedeliveryPolicy（bean名称RedeliveryPolicy）同时定义：IDP.ear/IDPEJB.jar!/META-INF/applicationContext.xml和SecureClaim.ear/SipsMessaging.jar!/META-INF/applicationContext.xml JtaTransactionManager（bean name transactionManager）定义于：RedeliveryPolicy（bean名称RedeliveryPolicy）同时定义：IDP.ear/IDPEJB.jar!/META-INF/applicationContext.xml和SecureClaim.ear/SipsMessaging.jar!/META-INF/applicationContext.xml 您必须确保需要包含所有这些applicationContext.xml文件。如果是这种情况（我真的怀疑，但仍然），你应该给你的豆子不同的名字。
为了更好地了解发生了什么，您可以在这里发布两个网络应用的web.xml吗？
