本文解决Struts2升级导致的依赖错误及Spring配置应用上下文加载失败的问题，通过修改web.xml中strutsfilter配置及使用FileSystemXmlApplicationContext解决。

1 No mapping found for dependency [type=java.lang.String, name='actionPackages

在升级到struts2-2.1.2报错主要信息如下：
Caused by: java.lang.RuntimeException: com.opensymphony.xwork2.inject.DependencyException: com.opensymphony.xwork2.inject.ContainerImpl$MissingDependencyException: No mapping found for dependency [type=java.lang.String, name='actionPackages'] in public void org.apache.struts2.config.ClasspathPackageProvider.setActionPackages(java.lang.String).

解决方法：如下

只要在web.xml中的struts filter加上actionPackages 如下所示：就OK啦

<filter>
<filter-name>struts</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.logo.group.webapp.action,com.logo.group.harvest.action</param-value>
</init-param>
</filter>

2 报出这样的错误：Error configuring application listener of class com.pdics.listener.ReceiveData
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [WEB-INF/applicationContext.xml]; nested exception is java.io.FileNotFoundException: class path resource [WEB-INF/applicationContext.xml] cannot be opened because it does not exist

解决方法：是 ctx = new FileSystemXmlApplicationContext("WebRoot/WEB-INF/applicationContext_db.xml");
.xml明显是文件么，怎么能用ClassPathXmlApplicationContext呢

就Ok了l
