Sitemesh 3 的使用及配置

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,类似于 ASP.NET 中的‘母版页’技术。参考:百度百科,相关类似技术:Apache Tiles。
官网:http://wiki.sitemesh.org/wiki/display/sitemesh/Home 。

2 . Sitemesh 3 下载

最新版本:3.0.0-SNAPSHOT
① GitHub 地址:https://github.com/sitemesh/sitemesh3
② maven:

<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 Sitemesh Filter:

<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 . 准备两个页面:demo.html 和 decorator.html

① demo.html - “被装饰的页面”,实际要呈现的内容页。

<!DOCTYPEhtml><html>    <head>        <title>内容页的标题</title>    </head>    <body>    内容页的body部分    </body></html>

② decorator.html - “装饰页面”,所谓的“母版页”。

<!DOCTYPE html><html>    <head>        <title>        <sitemesh:write property='title' /> - ltcms        </title>        <sitemesh:write property='head' />    </head>    <body>        <header>header</header>            <hr />                demo.html的title将被填充到这儿:                <sitemesh:write property='title' /><br />                demo.html的body将被填充到这儿:                <sitemesh:write property='body' />            <hr />        <footer>footer</footer>    </body></html>

5 .sitemesh配置方式

1)使用xml的配置方式:

添加 /WEB-INF/sitemesh3.xml

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

2)使用java代码的配置方式

java常用公共配置方式:

publicclassMySiteMeshFilterextendsConfigurableSiteMeshFilter{    @Override    protectedvoidapplyCustomConfiguration(SiteMeshFilterBuilder builder){        //Mapdefaultdecorator.Thisshallbeappliedtoallpathsifnootherpathsmatch.        builder.addDecoratorPath("/*","/default-decorator.html")        //Mapdecoratorstopathpatterns.        .addDecoratorPath("/admin/*","/another-decorator.html")        .addDecoratorPath("/*.special.jsp","/special-decorator.html")        //Mapmultipledecoratorstotheasinglepath.        .addDecoratorPaths("/articles/*","/decorators/article.html",        "/decoratos/two-page-layout.html",        "/decorators/common.html")        //Excludepathfromdecoration.        .addExcludedPath("/javadoc/*")        .addExcludedPath("/brochures/*");    }}

Note: If you also have an XML config file, SiteMesh will load this before calling applyCustomConfiguration(). This allows you to use XML for some configuration and Java for more advanced aspects.
注意:如果你同时拥有xml配置文件,sitemesh将会在调用applyCustomConfiguration() 前优先加载它。这种方式可以帮助你使用xml完成某些配置,然后使用java完成更高级的层面的配置

6 . 运行效果

访问 demo.html 页面,实际效果如下:

7 . sitemesh3.xml 配置详解

<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-->    <mappingdecorator="/default-decorator.html"/>    <!--对不同的路径,启用不同的装饰器-->    <mappingpath="/admin/*"decorator="/another-decorator.html"/>    <mappingpath="/*.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-->    <mappingpath="/javadoc/*"exclue="true"/>    <mappingpath="/brochures/*"exclue="true"/>    <!--自定义tag规则-->    <content-processor>        <tag-rule-bundleclass="com.something.CssCompressingBundle"/>        <tag-rule-bundleclass="com.something.LinkRewritingBundle"/>    </content-processor>    ...</sitemesh>

8 . 自定义 tag 规则

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:

publicclassMyTagRuleBundleimplementsTagRuleBundle{    @Override    publicvoidinstall(State defaultState,ContentProperty contentProperty    ,SiteMeshContext siteMeshContext){      defaultState.addRule("myHeader",      newExportTagToContentRule(contentProperty.getChild("myHeader"),false));    }    @Override    publicvoidcleanUp(State defaultState,ContentProperty contentProperty,    SiteMeshContext siteMeshContext){    }}

最后在 sitemesh3.xml 中配置即可:

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