问题描述
我知道我应该在配置文件或我自己的 ConfigurableSiteMeshFilter 的子类中定义装饰器。例如：
I know I should define decorators in a configuration file or my own subclass of ConfigurableSiteMeshFilter. For example:
public class SitemeshFilter extends ConfigurableSiteMeshFilter {
@Override
protected void applyCustomConfiguration(final SiteMeshFilterBuilder builder) {
builder.addDecoratorPath("/*", "/WEB-INF/views/layouts/default.jsp");
}
}
这对我有用，但这并不完美。我可以直接在JSP文件中定义要使用的装饰器吗？
This works for me but this isn't perfect. Can I define what decorator to use directly in a JSP file?
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html sitemesh:decorator="layouts/default.jsp"> <!-- something like this -->
<head>
<title>Home</title>
<meta content="test" name="description" />
</head>
<body>
<h1>Hello world!</h1>
${body}
</body>
</html>
推荐答案
使用元标记
我们一直这样做。
在您的sitemesh.xml中，允许该页面位于名为decorator的元标记中，如：
In your sitemesh.xml, allow the page to be in a meta tag named decorator like:
<decorator-mappers>
<mapper class="com.opensymphony.module.sitemesh.mapper.PageDecoratorMapper">
<param name="property.1" value="meta.decorator"/>
<param name="property.2" value="decorator" />
</mapper>
</decorator-mappers>
在decorators.xml中，添加一个装饰器，如：
In your decorators.xml, add a decorator like:
<decorators>
<decorator name="default" page="/WEB-INF/decorators/default.jsp" />
<decorator name="alternative" page="/WEB-INF/decorators/alternative.jsp" />
<decorators>
然后，在你的html或jsp页面中，你可以添加一个名为decorator的元标记来切换你的默认和替代模板：
Then, in your html or jsp page, you can add a meta tag called decorator to switch between your default and alternative templates:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<meta name="decorator" content="alternative" />
<title>Home</title>
<meta content="test" name="description" />
</head>
<body>
<h1>Hello world!</h1>
${body}
</body>
</html>
