Apache Tiles: how to access definition name
I want to write the tiles definition name direct into the templates. But I have no idea how to access the definition name.
To illustrate what I want to do have a look at this workaround:
<tiles-definitions>
<definition extends="default" name="index">
<put-attribute name="body" value="/WEB-INF/views/index.jspx"/>
<put-attribute name="pageId" value="index"/> 开发者_如何学运维
</definition>
<definition extends="default" name="login">
<put-attribute name="body" value="/WEB-INF/views/login.jspx"/>
<put-attribute name="pageId" value="login"/>
</definition>
</tiles-definitions>
Default Template:
<html>
...
<tiles:useAttribute id="tiles_pageId" name="pageId" classname="java.lang.String" />
<body id="pageId_${tiles_pageId}">
...
</body>
</html>
This works. I can specify an attribute (pageId) in the definition, read it in the template and write it in the template output.
But you see there is a 1:1 correlation between definition name and pageId. So I do not want to write the name twice (definition name and pageId) in the definition. Instead I am looking for a way to skip the pageId attribute declaration and get the definition name somehow else in the template (without writing it twice again and again.)
I think you can use Wildcard in your definition
<definition extends="default" name="*">
<put-attribute name="body" value="/WEB-INF/views/{1}.jspx"/>
<put-attribute name="pageId" value="{1}"/>
</definition>
