1.从官网下载一个jar包 sitemesh-3.0.1.jar

2.在web项目里的web.xml 添加过滤器

  <filter>    <filter-name>sitemesh</filter-name>    <filter-class>org.sitemesh.config.ConfigurableSiteMeshFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>sitemesh</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>

3.新建sitemesh3.xml ，名字必须是sitemesh3

<?xml version="1.0" encoding="UTF-8"?><sitemesh>    <!-- 指明满足“/*”的页面，将被“/WEB-INF/views/decorators/decorator.html”所装饰 -->    <mapping path="/*" decorator="/decorator.html" />    <!-- 指明满足“/exclude.jsp*”的页面，将被排除，不被装饰 -->    <mapping path="/exclude.jsp*" exclue="true" /></sitemesh>

4.设置decorator.html

<!DOCTYPE html><html>  <head>    <title>SiteMesh example: <sitemesh:write property='title'/></title>    <style type='text/css'>      /* Some CSS */     body { font-family: arial, sans-serif; background-color: #ffffcc; }     h1, h2, h3, h4 { text-align: center; background-color: #ccffcc;                      border-top: 1px solid #66ff66; }     .mainBody { padding: 10px; border: 1px solid #555555; }     .disclaimer { text-align: center; border-top: 1px solid #cccccc;                   margin-top: 40px; color: #666666; font-size: smaller; }    </style>    <sitemesh:write property='head'/>  </head>  <body>    <h1 class='title'>this is a title<sitemesh:write property='title'/></h1>    <div class='mainBody'>      this BODY<sitemesh:write property='body'/>fff<sitemesh:write property='body'/>    </div>    <div class='disclaimer'>Site disclaimer. This is an example.</div>  </body></html>

<sitemesh:write property='xxxx'/>标签就是原网页的内容（粗粒度的），可以多次加载

5.然后运行，打开要被渲染的网页就行了。原理：被渲染的网页在输出前会因为上面的配置，其实会加载decorator.html网页，并输出。
