这里是Sitemesh跟struts2的整合配置，顺序不能反过来，否则无法解析struts2的标签等问题。
web.xml
--------------------

<filter>  
        <filter-name>sitemesh</filter-name>  
        <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>  
    </filter>  

    <filter-mapping>  
        <filter-name>sitemesh</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

decorators.xml

---------------------

<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/decorators">
       <!-- used whit main.jsp -->
       <decorator name="main" page="main.jsp">
           <pattern>/*</pattern>
       </decorator>
</decorators>

<pattern>/*</pattern>这里要小心,strtus.xml的package里面的namespace,和默认的空间是否相应。否则问题出现了,很难找到。一般就直接要"/*", 尽量不要加用"/pages/*"之类的。

一个需要注意的地方:

<excludes>
        <pattern>/error.jsp</pattern>
     </excludes>

当这个排除失效的时候,请改成:

<decorator name="none">
      <pattern>/excludes/*</pattern>
      <pattern>/error.jsp</pattern>
     </decorator>
