Java

Sitemesh 3 简介

Sitemesh 是一个网页布局和修饰的框架，基于 Servlet 中的 Filter
!

使用及配置说明

项目demo基于sitemesh-3.0.1

在pom添加依赖

<dependency>
    <groupId>org.sitemesh</groupId>
    <artifactId>sitemesh</artifactId>
    <version>3.0.1</version>
</dependency>

web.xml 添加拦截器

<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>

创建 sitemesh3.xm (默认在/WEB-INFO/sitemesh3.xml 必须是这个名字 Hard Code)

sitemesh3提供2种配置方式 java和xml，具体请看Configuring SiteMesh 3

<?xml version="1.0" encoding="UTF-8"?>
<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="/defaulmain.jsp"/>
    <!-- 指明满足"*.jsp"的页面，将被"main.jsp"所装饰 -->
    <mapping path="*.jsp" decorator="/views/sitemesh3/main.jsp" />
    <!-- 指明满足"/exclude.jsp*"的页面，将被排除，不被装饰 -->
    <mapping path="/exclude.jsp" exclue="true" />
    <!-- 自定义标签 -->
    <content-processor>
        <tag-rule-bundle class="com.github.dzhai.sitemesh.tag.HeaderTagRuleBundle" />
        <tag-rule-bundle class="com.github.dzhai.sitemesh.tag.FooterTagRuleBundle" />
    </content-processor>
</sitemesh>

创建模板文件 main.jsp

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<title><sitemesh:write property='title' /> -sitemesh</title>
<sitemesh:write property='head' />
</head>
<body>
    <header>header - <sitemesh:write property='header' /></header>
    <sitemesh:write property='body' />
    <footer>footer - <sitemesh:write property='footer' /></footer>
</body>
</html>

创建具体页面index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<html>
<head>
<title>index页面标题</title>
<script type="text/javascript">
    alert('script');
</script>
</head>
<body>
    <header>my header</header>
    <h2>Hello World!</h2>
    <footer>my footer</footer>
</body>
</html>

自定义tag

FooterTagRuleBundle

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

HeaderTagRuleBundle

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

运行项目访问 index.jsp

!此处输入图片的描述
生成html源码

<!DOCTYPE html>
<html>
<head>
<title>index页面标题 -sitemesh</title>
<script type="text/javascript">
    alert('script');
</script>
</head>
<body>
    <header>header - my header</header>
    <h2>Hello World!</h2>
    <footer>footer - my footer</footer>
</body>
</html>
