[还在加载中灬]

搬来的...

如果是2.1.3之前的版本，用org.apache.struts2.dispatcher.FilterDispatcher，
否则，用org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。
从Struts2.1.3开始，将废弃ActionContextCleanUp过滤器，而在StrutsPrepareAndExecuteFilter过滤器中包含相应的功能。

三个初始化参数：
1、config参数：指定要加载的配置文件。逗号分割。
2、actionPackages参数：指定Action类所在的包空间。逗号分割。
3、configProviders参数：自定义配置文件提供者，需要实现ConfigurationProvider接口类。逗号分割。

如果程序报类找不到异常，且后面有 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter 等信息，可能是你的版本问题.解决方法是确定你的struts版本， 如果是2.1.3之前的版本，用 org.apache.struts2.dispatcher.FilterDispatcher，以后的版本则配置org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
