从其他Maven模块导入Spring bean

Question

我目前有我的应用程序的以下Maven模块：规则，持久性，服务器，其中每个都包含一个applicationContext.xml文件相互导入（即。导入导入persistenceAC的rulesAC ，所有AC文件都位于{对应模块}/src/main/resources中）。虽然我的IDE（的IntelliJ），集成测试和Maven包中的所有构建，并通过精细在尝试启动我的服务器我笑脸相迎：

“富”无法找到bean是从persistenceAC.xml 。顺便我导入每个孩子的AC的是：

<import resource="classpath*:rulesAC.xml"/> 

我也tryed这种进口的每一个变化（“类路径：rulesAC.xml”，“类路径*：/ rulesAC.xml”，“类路径：/rulesAC.xml“）认为这是问题，但似乎并非如此。

虽然我认为这是某种类路径问题，但我已经尝试了解我所知道的一切，并试图寻找解决方案而没有多少运气。预先感谢您的帮助，如果还有其他任何帮助，请通知。

注意*服务器模块包含规则模块和持久性模块上的依赖关系。

您列出的所有导入变体都应该有效。事实上，如果他们不这样做，Spring在尝试加载文件时会得到一个IOException。缺少这种情况表明文件存在并正在加载，或者包含导入的文件未加载。查找INFO级别的日志，显示Spring正在加载哪些XML文件以及每个ApplicationContext中加载了哪些singleton bean。这会引导您发现配置错误。日志看起来像：

Loading XML bean definitions from <description of resource> 
Pre-instantiating singletons in <type of application context> <list of singleton beans>
