SiteMesh2-sitemesh.xml的ConfigDecoratorMapper映射器的用法

继上一次的示例工程http://www.cnblogs.com/EasonJim/p/7083165.html，使用的就是ConfigDecoratorMapper映射器，通过指定目录下的页面，都同一走模板页。

在使用上，只需设置两处地方，在基础页面无需配置。

1、decorators.xml

<?xml version="1.0" encoding="UTF-8"?>

<decorators defaultdir="/decorators">

    <decorator name="basic-theme" page="basic-theme.jsp">

        <pattern>/data/*</pattern>

    </decorator>

</decorators>

2、sitemesh.xml

<sitemesh>

    <property name="decorators-file" value="/WEB-INF/decorators.xml"/>

    <excludes file="${decorators-file}"/>

    <page-parsers>

        <parser content-type="text/html" class="com.opensymphony.module.sitemesh.parser.HTMLPageParser" />

    </page-parsers>

    <decorator-mappers>

        <mapper class="com.opensymphony.module.sitemesh.mapper.PageDecoratorMapper">

            <param name="property.1" value="meta.decorator" />

            <param name="property.2" value="decorator" />

        </mapper>

        <mapper class="com.opensymphony.module.sitemesh.mapper.FrameSetDecoratorMapper"/>

        <mapper class="com.opensymphony.module.sitemesh.mapper.PrintableDecoratorMapper">

            <param name="decorator" value="printable" />

            <param name="parameter.name" value="printable" />

            <param name="parameter.value" value="true" />

        </mapper>

        <mapper class="com.opensymphony.module.sitemesh.mapper.FileDecoratorMapper"/>

        <mapper class="com.opensymphony.module.sitemesh.mapper.ConfigDecoratorMapper">

            <param name="config" value="${decorators-file}" />

        </mapper>

    </decorator-mappers>

</sitemesh>

说明：page-parsers节点这个不经常使用，保持默认即可。
