struts2.1.8+sitemesh-2.4.2+urlrewrite-2.6.0web.xml不同的配置方式导致不同的功能

本文介绍两种Struts2与Sitemesh整合的方法。一种是通过物理路径进行装饰，另一种则是通过URL请求来实现装饰效果。详细展示了不同配置方式下的web.xml文件设置。

整合方式有二种，主要是取决于sitemesh如何配置。

跟上一篇文章struts2+sitemesh一样的配置方式（一种是按物理路径进行装饰，一种是按url请求进行装饰）。

首先说下第一种：

web.xml配置方式如下（主要配置struts2.1.8,sitemesh-2.4.2,urlrewrite-2.6.0的filter-mapping）:

     <filter-mapping>
          <filter-name>UrlRewriteFilter</filter-name>
          <url-pattern>/*</url-pattern>
          <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
      </filter-mapping>

    <filter-mapping>
        <filter-name>struts-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

第二种方式：

<filter-mapping>
         <filter-name>UrlRewriteFilter</filter-name>
         <url-pattern>/*</url-pattern>
         这二行一定要注释掉，否则sitemesh报错
        
    </filter-mapping>

    <filter-mapping>
        <filter-name>struts-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>
