sitemesh 与velocity ,freemarker �l�合�?参考资�?sitemesh-example.war)
准备�Q�commmons-collections.jar, freemarker.jar sitemesh-2.3.jar velocity-dep-1.3.1.jar velocity-tools-view-1.1.jar
(1)sitemesh 与velocity
web.xml

    <servlet>
        <servlet-name>sitemesh-velocityservlet-name>
        <servlet-class>
            com.opensymphony.module.sitemesh.velocity.VelocityDecoratorServlet
        servlet-class>
        <load-on-startup>10load-on-startup>

    <servlet-mapping>
        <servlet-name>sitemesh-velocityservlet-name>
        <url-pattern>*.vmurl-pattern>
    servlet-mapping>

decorators/velocity.vm

<html>
    <head>
        <title>Velocity Decorator - $titletitle>
        <link href="$base/decorators/main.css" rel="stylesheet" type="text/css">
        $head
    head>
    <body>
      <div id="pageTitle">$titlediv>
      <hr/>
      $body
      <div id="footer">
          <b>Disclaimer:b> This site is an example site to demonstrate SiteMesh. It serves no other purpose.
      div>
    body>
html>

与一�ơ的代码是差不太多，只不�q�用$标记来代替以前的
�~�写 WebRoot/velocity.html

<html>
    <head>
        <title>Velocity Testtitle>
    head>
    <body>
        <p>This page is decorated by the VelocityDecoratorServlet.p>
        <p>Go <a href="index.html">backa>.p>
    body>
html>

把velocity.html映射到velocity.vm上�?br /> WEB-INF/decorators.xml��d��如下映射.

<decorator name="velocity" page="velocity.vm">
<pattern>/velocity.htmlpattern>
decorator>

再运行程�?http://localhost/sitemesh/velocity.html��可看到映射后的样式了， sitemesh与velocity�l�合�?br /> (2) sitemesh 与freemarker
与上例同步�?br /> web.xml 加入如下servlet 映射�Q?br />

    <servlet>
        <servlet-name>sitemesh-freemarkerservlet-name>
        <servlet-class>
            com.opensymphony.module.sitemesh.freemarker.FreemarkerDecoratorServlet
        servlet-class>
        <init-param>
            <param-name>TemplatePathparam-name>
            <param-value>/param-value>
        init-param>
        <init-param>
            <param-name>default_encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>sitemesh-freemarkerservlet-name>
        <url-pattern>*.ftlurl-pattern>
    servlet-mapping>

��d��Q�decorators/freemarker.ftl

<html>
    <head>
        <title>Freemarker Decorator - ${title}title>
        <link href="${base}/decorators/main.css" rel="stylesheet" type="text/css">

    head>
    <body>

      ${body}
      <div id="footer">

      div>
    body>
html>

��d��Q�webRoot/freemarker.html

<html>
    <head>
        <title>Freemarker Testtitle>
    head>
    <body>
        <p>This page is decorated by the FreemarkerDecoratorServlet.p>
        <p>Go <a href="index.html">backa>.p>
    body>
html>

��d��两者之间的映射�Q�WEB-INF/decorators.xml

<decorator name="freemarker" page="freemarker.ftl">
<pattern>/freemarker.htmlpattern>
decorator>

�q�行http://localhost/sitemesh/freemarker.html .卛_��看到�l�果�?br /> 今天��到�q�里�Q�先�q�样吧�?br />

�Q?�Q�printable 装饰�?page 用法�?br /> 当要打印��面内容�Ӟ��不想要一些边�Ҏ(gu��)��框。只��x��惌��的内容，讄��为printable decorators 卛_��?br /> sitemesh 讄��Ҏ(gu��)��如下�Q?br /> setemesh.xml

上面代码��|?nbsp; 打印的属性及(qi��ng)参数�?printable=true链接到打印模式上�?br /> decorators.xml

功能�Q�将name="printable" 的装饰映��到printable.jsp上�?br /> printable.jsp

<%@ taglib uri="http://www.opensymphony.com/sitemesh/decorator" prefix="decorator" %>
<html>
    <head>
        <title><decorator:title default="NO Title" />title>
        <decorator:head />
    head>
    <body>
        <h1><decorator:title  default="No Title"/>h1>
        <p align="right"><i>(printable version)i>p>
        <decorator:body />
    body>
html>

�q�是参照官方上的例子的printable.jsp.注意。当链接指向�Ӟ��没有标题�Ӟ��昄��No Title .当没有body部分�Ӟ��则会(x��)出现null point error(我出��C��q�个错误�Q�不知道是不是我机子的问�?
按照上述配置后：(x��)当访问：(x��)http://localhost/sitemesh/index.jsp?printable=true �Ӟ��只能显�C�index.jsp未被修饰的数据�?br /> 再进行修改就是在��面上加一个超�U�链接到些页面打印状态�?br /> 在decorators/main.jsp中加入以下代�?

        <decorator:usePage id="p" />
        <%
            HttpServletRequest req = p.getRequest();
            StringBuffer printUrl = new StringBuffer();
            printUrl.append( req.getRequestURI() );
            printUrl.append("?printable=true");
            if (request.getQueryString()!=null) {
                printUrl.append('&');
                printUrl.append(request.getQueryString());
            }
        %>
        <p align="right">[ <a href="<%= printUrl %>">printable versiona> ]p>

�q�样��在每个��面都添加上了，打印式的��链接�? 是获得了��面的page对象�?br /> �Q?�Q�page:applyDecorator 用法�Q�把某一个页面进行某�U�样式的映射�?lt;page:applyDecorator page="*.jsp" name="*" />
�?.jsp映射到decorators.xml 中定义的* 装饰上�?br /> 例子�Q?br />

<page:applyDecorator name="panel" page="/date.jsp" >
