：
说一下，以下错误弄了不时间，加上网上版本各有不同：
XmlConfigurationProvider这里有一个属性：objectFactory，看是否指向org.apache.
struts2.spring.StrutsSpringObjectFactory，若不是
加载失败，将会出包Action class not found的错误(ioc失败)，因为默认是使用org.apache.struts2.impl.StrutsObjectFactory加载的，
这里主要是说明如何使用spring的ioc强大功能

<!--不知为何这句话一定写在这里，很多文档说可以写到struts.properties中写成...=spring,
我试了不知为何不何，那为朋友知道给我信息啦，struts.properties在src目录下，
没这句话，将会用org.apache.struts2.impl.StrutsObjectFactory加载action,就无法使用spring的ioc
使用这话，一定要把struts2-spring-plugin-2.1.8.1.jar放到classpath中
可以使用以下<include file="struts-plugin.xml"/>这句话，替换
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
因为在spring插件中已有定义，<include file="struts-plugin.xml"/>这句话会默认加载所有插件的配置，如json之类的

jar:
struts的基本包(我的是struts2.18)；
spring的基本包(2.5)
struts2-spring-plugin-2.1.8.1.jar，这个是ioc的包
