能解决这个问题还真是要感谢 http://blog.csdn.net/qjyong/archive/2008/11/16/3311688.aspx这篇文章的作者qjyong。参照他的方法我在SSH中完成了不同方法验证需求不同的操作。
1. 自定义的FileChecks类。这里对qjyong的FileChecks稍微做了一下改动。应该使用SSH框架以后，使用的Action都写成org.springframework.web.struts.DelegatingActionProxy。所以在这种情况下Class.forName(className).newInstance() instanceof DispatchAction永远都为false.下面只把改动的代码注释出来，其它的都参考qjyong的。

<Context reloadable="true" privileged="true">
The invoker servlet lets you run servlets without first making changes to your Web application's deployment descriptor (i.e., the WEB-INF/web.xml file). Instead, you just drop your servlet into WEB-INF/classes and use the URL http://host/servlet/ServletName (or http://host/webAppName/servlet/ServletName once you start using your own Web applications. The invoker servlet is extremely convenient when you are learning and even when you are testing things doing your initial development. You almost certainly want to enable it when learning, but you should disable it again before deploying any real applications.
To enable the invoker servlet, uncomment the following servlet and servlet-mapping elements in install_dir/conf/web.xml. Do not confuse this Apache Tomcat-specific web.xml file with the standard one that goes in the WEB-INF directory of each Web application.
