问题
Say I have a resources/ folder in the webroot. In it, I have a css/ folder and in it there is a theme.css file.
But I want to set an Expires: header. Therefore I want to use a version for resource libraries, say
<h:outputStylesheet library="css" name="theme.css"/>
would turn into
<link rel="stylesheet" src="javax.faces.resources/theme.css.xhtml?ln=css"/>
But I want to specify something like
<h:outputStylesheet library="css" name="theme.css" version="1.2"/>
And get
<link rel="stylesheet" src="javax.faces.resources/theme.css.xhtml?ln=css&v=1_2"/>
or similar. I have read that JSF2 has support for resource versioning, but how do I specify which version to load, and where do I put the files?
回答1:
If you suppose to have the css library, you should use this directories naming scheme:
resources/css/1_1
resources/css/1_2
where resources in the jsf standard resource directory
