SiteMesh使用(2.4.2)

SiteMesh是一个网页布局和修饰的框架。我理解的是在一个母版页上引入页面各个位置的信息,从而拼接成一个页面展示出来。它定义了一个过滤器,把页面统一加上头部和底部。

我的项目是在springmvc中使用的,目录结构

首先引入sitemesh的jar包

在web.xml中添加过滤器

<!-- SiteMesh -->
    <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>/a/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>sitemeshFilter</filter-name>
        <url-pattern>/f/*</url-pattern>
    </filter-mapping>

在WEB-INfO下的decorators.xml配置母版页

<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.jsp"/>
  
  <!-- 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>

其中default.jsp就是母版页

default.jsp:<%@ page contentType="text/html;charset=UTF-8"%>

<%@ include file="/WEB-INF/views/modules/cms/front/include/taglib.jsp"%>
<%@ taglib prefix="sitemesh" uri="http://www.opensymphony.com/sitemesh/decorator" %>
<!DOCTYPE html>
<html>
<head>
    <title>
  //title.jsp将会被填充到这里
   <
sitemesh:title default="欢迎光临"/> - ${site.title} - Powered By JeeSite</title> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no">

//head.jsp将会被填充到这里
<sitemesh:head/> </head> <body>

//body将会被填充到这里(也就是经过过滤器的需要被渲染的页面)
   <sitemesh:body/>

</body> </html>

===================================================================== 

自定义规则tag(Sitemesh 3 默认只提供了 body,title,head 等 tag 类型,我们可以通过实现 TagRuleBundle 扩展自定义的 tag 规则:)

public class MyTagRuleBundle implements TagRuleBundle {
    @Override
    public void install(State defaultState, ContentProperty contentProperty,
            SiteMeshContext siteMeshContext) {
        defaultState.addRule("myHeader", new ExportTagToContentRule(contentProperty.getChild("myHeader"), false));
        
    }
    
    @Override
    public void cleanUp(State defaultState, ContentProperty contentProperty,
            SiteMeshContext siteMeshContext) {
    }
}

 配置文件中添加调用

1 <content-processor>
2     <tag-rule-bundle class="com.lt.common.ext.sitemesh3.MyTagRuleBundle" />
3 </content-processor>
