1、Sitemesh 3 简介
Sitemesh 是一个网页布局和修饰的框架，基于 Servlet 中的 Filter。
官网：http://wiki.sitemesh.org/wiki/display/sitemesh/Home 。
2、Sitemesh 3 下载
这里使用Maven下载，pom.xml
<dependency>
<groupId>org.sitemesh</groupId>
<artifactId>sitemesh</artifactId>
<version>3.0.0</version>
</dependency>
3、配置 Sitemesh 3 过滤器
在web.xml中添加一下过滤器
<web-app>
...
<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>
</web-app>
4、准备一下两个页面
webapp/demo.jsp 和 webapp/WEB-INF/views/decorators/decorator.jsp
demo.jsp - "被装饰的页面"，实际要呈现的内容页
<%@ 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">
<title>中文标题·</title>
</head>
<body>
中文内容
</body>
</html>
decorator.jsp - "装饰页面"，所谓的"模板页面"
<%@ 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">
<title>
<sitemesh:write property="title" /> - ltcms
</title>
<sitemesh:write property="head" />
</head>
<body>
<header>header</header>
<hr />
demo.html的title将会填充在这里；
<sitemesh:write property="title" />
<br /> demo.html的body将会填充在这里；
<sitemesh:write property="body" />
<br />
<hr />
<footer>footer</footer>
</body>
</html>
5、 添加 /WEB-INF/sitemesh3.xml
<?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="/WEB-INF/view/decorators/decorator.jsp" />
<!-- 指明满足“/exclude.jsp*”的页面，将被排除，不被装饰 -->
<mapping path="/exclude.jsp*" exclue="true" />
</sitemesh>
6、运行效果
运行结果
7、sitemesh3.xml详细配置
<sitemesh>
<!--默认情况下，
sitemesh 只对 HTTP 响应头中 Content-Type 为 text/html 的类型进行拦截和装饰，
我们可以添加更多的 mime 类型-->
<mime-type>text/html</mime-type>
<mime-type>application/vnd.wap.xhtml+xml</mime-type>
<mime-type>application/xhtml+xml</mime-type>
...
<!-- 默认装饰器，当下面的路径都不匹配时，启用该装饰器进行装饰 -->
<mapping decorator="/default-decorator.html"/>
<!-- 对不同的路径，启用不同的装饰器 -->
<mapping path="/admin/*" decorator="/another-decorator.html"/>
<mapping path="/*.special.jsp" decorator="/special-decorator.html"/>
<!-- 对同一路径，启用多个装饰器 -->
<mapping>
<path>/articles/*</path>
<decorator>/decorators/article.html</decorator>
<decorator>/decorators/two-page-layout.html</decorator>
<decorator>/decorators/common.html</decorator>
</mapping>
<!-- 排除，不进行装饰的路径 -->
<mapping path="/javadoc/*" exclue="true"/>
<mapping path="/brochures/*" exclue="true"/>
<!-- 自定义 tag 规则 -->
<content-processor>
<tag-rule-bundle class="com.something.CssCompressingBundle" />
<tag-rule-bundle class="com.something.LinkRewritingBundle"/>
</content-processor>
...
</sitemesh>
