Sitemesh 3 配置和使用(最新)

一 Sitemesh简介

• Sitemesh是一个页面装饰器,能够快速的建立有统一外观Web应用 -- 导航 加 布局 的统一方案~
• Sitemesh能够拦截任何动态或则静态的HTML页面的请求,Sitemesh处理后把一个或多个装饰器组装成最后结果返回
• Sitemesh能够把一个大页面分红不少小的页面来布局

Sitemesh官网简介图片简单明了,一目了然 .. welcome Page和search Page包含两部分 Meta-Data 和 Body-Content , 经过装饰器后被装饰返回一个最终的页面 final pages.

二 Maven中使用Sitemesh 3

在Maven工程的Pom中添加依赖 ~

<dependency>
    <groupId>org.sitemesh</groupId>
    <artifactId>sitemesh</artifactId>
    <version>3.0.0</version>
</dependency>

---

三 在web.xml中配置Sitemesh 3 拦截器

<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>

四 sitemesh 3 的配置

sitemesh 3 有两种配置方式 XML和Java

1 XML配置详解

添加一个 ~ /WEB-INF/sitemesh3.xml

<sitemesh>

    <!-- 默认的装饰路径。若是没有配置其余的路径将启用默认路径,这个能够适用于全部路径 -->
    <!-- Map default decorator. This shall be applied to all paths if no other paths match. -->
    <mapping decorator="/default-decorator.html"/>

    <!-- 配置装饰器的路径 -->
    <!-- Map decorators to path patterns. -->
    <mapping path="/admin/*" decorator="/another-decorator.html"/>
    <mapping path="/*.special.jsp" decorator="/special-decorator.html"/>

    <!-- 对同一路径配置多个装饰器 -->
    <!-- Alternative convention. This is more verbose but allows multiple decorators
         to be applied to a single path. -->
    <mapping>
        <path>/articles/*</path>
        <decorator>/decorators/article.html</decorator>
        <decorator>/decorators/two-page-layout.html</decorator>
        <decorator>/decorators/common.html</decorator>
    </mapping>

    <!-- 配置 不被装饰 的路径 -->
    <!-- Exclude path from decoration. -->
    <mapping path="/javadoc/*" exclue="true"/>
    <mapping path="/brochures/*" exclue="true"/>

    <!-- 默认状况下，
         sitemesh 只对 HTTP 响应头中 Content-Type 为 text/html 的类型进行拦截和装饰，
         咱们也能够添加更多的 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>

    <!--
    Sitemesh 3 默认只提供了 body，title，head 种 tag 类型
    咱们能够添加自定义的tag规则 -->
    <content-processor>
        <tag-rule-bundle class="com.something.CssCompressingBundle" />
        <tag-rule-bundle class="com.something.LinkRewritingBundle"/>
    </content-processor>

</sitemesh>

4 Java的配置方式

package com.erma.common;

import org.sitemesh.builder.SiteMeshFilterBuilder;
import org.sitemesh.config.ConfigurableSiteMeshFilter;

/**
 * Created by Erma on 2017/4/13.
 */
public class MySiteMeshFilter extends ConfigurableSiteMeshFilter {

    @Override
    protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
        // 默认的装饰器
        // Map default decorator. This shall be applied to all paths if no other paths match.
        builder.addDecoratorPath("/*", "/default-decorator.html")
                // 配合 本身 的 路径对应的装饰器
                // Map decorators to path patterns.
                .addDecoratorPath("/admin/*", "/another-decorator.html")
                .addDecoratorPath("/*.special.jsp", "/special-decorator.html")
                //一个路径多个装饰器
                // Map multiple decorators to the a single path.
                .addDecoratorPaths("/articles/*", "/decorators/article.html",
                        "/decoratos/two-page-layout.html",
                        "/decorators/common.html")
                // 配置不被装饰的路径
                // Exclude path from decoration.
                .addExcludedPath("/javadoc/*")
                .addExcludedPath("/brochures/*");

        // 配置本身的MineType
        builder.setMimeTypes("text/html", "application/xhtml+xml", "application/vnd.wap.xhtml+xml");
        // 配置本身的tag
        builder.addTagRuleBundles(new CssCompressingBundle(), new LinkRewritingBundle());
    }
}

五 Sitemesh 3 的使用

下面是使用 intellij + Maven + Sitemsehxml的配置方式的一个使用

1 配置Maven的pom 和web.xml按照上面的方式

2 配置sitemseh.xml

<sitemesh>

    <!-- 拦截任何路径配置装饰器 -->
    <mapping path="/*" decorator="/WEB-INF/jsp/layouts/decorator.jsp"/>

    <!-- 这里配置自定义的tag -->
    <content-processor>
        <tag-rule-bundle class="com.erma.common.MySiteMeshFilter"/>
    </content-processor>

</sitemesh>

3 配置自定义的tag

package com.erma.common;

import org.sitemesh.SiteMeshContext;
import org.sitemesh.content.ContentProperty;
import org.sitemesh.content.tagrules.TagRuleBundle;
import org.sitemesh.content.tagrules.html.ExportTagToContentRule;
import org.sitemesh.tagprocessor.State;

/**
 * Created by Erma on 2017/4/13.
 */
public class MySiteMeshFilter implements TagRuleBundle {


    public void install(State state, ContentProperty contentProperty, SiteMeshContext siteMeshContext) {
        state.addRule("myTag", new ExportTagToContentRule(siteMeshContext,contentProperty.getChild("myTag"),false));
    }

    public void cleanUp(State state, ContentProperty contentProperty, SiteMeshContext siteMeshContext) {

    }
}

4 配置模板

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>
        <sitemesh:write property='title'/>
    </title>
    <sitemesh:write property='head'/>
</head>
<body>

我是装饰器 : title的内容在这里 ~ <sitemesh:write property='title'/><br/>

我是装饰器 : body的内容在这里 ~ <sitemesh:write property='body'/><br/>

我是装饰器 : myTag的内容在这里 ~ <sitemesh:write property='myTag'/><br/>

</body>
</html>

5 home.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>我是标题~</title>
</head>
<body>

<myTag>
    我是自定义的tag
</myTag>

嗨喽嗨喽 ~
</body>
</html>
