今天作struts2和spring的集成，由于以前我们的开发框架webwork+spring所以按照以前的思路进行修改了配置文件的路径，也就是自定义了config的配置，然后出现如下问题：
com.opensymphony.xwork2.inject.DependencyException: com.opensymphony.xwork2.inject.ContainerImpl$MissingDependencyException: No mapping found for dependency [type=com.opensymphony.xwork2.ObjectFactory, name='default'] in public void com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.setObjectFactory(com.opensymphony.xwork2.ObjectFactory).

查询了半天，看网上有人碰到过，但是没有解决，于是分析代码进行查询原因，原因就是配置文件struts配置文件没有找到，于是想到了修改的配置，经过查询代码发现了这个问题，就是如果你要是修改了config，以后所有的配置只会读取配置的文件，所以struts-spring.jar等插件都采用的default的配置，所以会出错，故修改config的配置，把default的文件全部添加上，然后再添加上自己的配置文件，本来可以采用Dispatcher的DEFAULT_CONFIGURATION_PATHS然后添加自己的配置文件就可以，但是发现这个变量是private的，所有只能把里面的内容全部拷贝出来，所以这个地方的扩展自定义功能也是没有太大意义的。
