通過SiteMesh的頁面裝飾，可以提高更好的代碼複用，以下是配置使用的簡單記錄:
1.下載jar包：sitemesh-2.3.jar，將jar複製到lib目錄下
2.web.xml文件中配置sitemesh的Filter
<!-- 配置裝飾器filter -->
<filter>
<filter-name>sitemeshFilter</filter-name>
<filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemeshFilter</filter-name>
<url-pattern>/jsp/*</url-pattern>
</filter-mapping>
3.新建一個decorators.xml文件：
<decorators defaultdir="/WEB-INF/jsp">
<!-- 配置裝飾器頁面-->
<decorator name="decorator" page="/jsp/decorator.jsp" >
<!-- 配置需要追加裝飾器的頁面 -->
<pattern>/jsp/*</pattern>
</decorator>
<!-- 配置不需要追加裝飾的頁面 -->
<excludes>
<pattern>/jsp/decorator*</pattern>
</excludes>
</decorators>
4.新建裝飾頁面decorator.jsp
- <%@ page contentType="text/html;charset=UTF-8"%>
