1.安装sitemesh插件
与整合其他框架类似，struts2与sitemesh框架的整合也使用了插件方式进行管理。将struts2-sitemesh-plugin-2.0.6.jar文件复制到WEB-INF/lib下，为了整合sitemesh框架，必须在web.xml中配置sitemesh过滤器，让该核心过滤器来过滤所有的用户请求。但我们知道，struts2的所有值一旦访问该stack context或ValueStack后，里面对应的数值将会被清除掉，如果先使用了struts2的FilterDispather来过滤用户请求，则sitemesh的过滤器将无法取得Stack context或者ValueStack中的数据
为了解决这个问题，struts2提供了ActionContextCleanUp类，在struts2的架构中，标准的过滤器一般以ActionContextCleanUp开始，后面跟着其他需要的过滤器，最后，由FilterDispatcher来处理请求，FilterDispatcher通常是将请求传递给ActionMapper
ActionContextCleanUp的一个重要作用是整合sitemesh页面装饰器，它通知FilterDispatcher在正确的时间清除ActionContext中的请求数据，所以正确的排序如下：
（1）ActionContextCleanUp过滤器
（2）SiteMesh核心过滤器
（3）FilterDispatcher过滤器
