繼上一章http://www.cnblogs.com/EasonJim/p/7083165.html中使用的例子中，是通過decorators.xml檔案通過URL匹配進行轉換的。
而下面這種方法是通過sitemesh.xml的PageDecoratorMapper映射器來轉換的，而無需匹配URL，只需在meta頭指定decorator中的模板即可。
下面是操作步驟：
1、在sitemesh.xml中添加PageDecoratorMapper映射器，並指定meta的名稱規則
<mapper class="com.opensymphony.module.sitemesh.mapper.PageDecoratorMapper"> <param name="property.1" value="meta.decorator" /> <param name="property.2" value="decorator" /> <!-- 注意這一行指定<meta/>標籤的 name 屬性作為PageDecorator的識別符號 --> <param name="property.3" value="meta.theme" /> </mapper>
用法：
①<meta name="decorator" content="basic-theme" />
②<meta name="them" content="basic-theme" />
③<param name="property.2" value="decorator" />這個用法暫時不知道怎麼用。
注意：content指定的就是在decorators.xml檔案中docorator的模板名稱。
2、在decorators.xml的模板配置還是使用原來的
<decorators defaultdir="/decorators"> <decorator name="basic-theme" page="basic-theme.jsp"> <pattern>/data/*</pattern> </decorator></decorators>
3、在根目錄建立index.jsp頁面，內容如下：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="decorator" content="basic-theme" /><title>應該是內容頁面</title></head><body> <h1>Weekdays</h1> <p>5:00pm - 10:00pm</p> <p>Weekends</p> <p>5:00pm - 10:00pm</p></body></html>
4、測試效果如下：
