SSH开发的初期会有很多人碰到这个错误
原因是在struts-config.xml中配置了org.springframework.web.struts.ContextLoaderPlugIn
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml"/>
</plug-in>
然而又加载不到这个类，当然会报ClassNotFoundException
这个类是和Struts的整合类，并没有在spring-core.jar等文件中，而是在spring-webmvc-struts.jar中。
把spring-webmvc-struts.jar加载到ClassPath中就OK了。
如果找不到在哪里可以查找这个JAR增加到lib库文件里，用myeclipse的可以再这个路径查找到
D:\Program Files\MyEclipse\MyEclipse 10\configuration\org.eclipse.osgi\bundles\97\1\.cp\data\2.5\dist\modules\spring-webmvc-struts.jar
