How can I remove HTML comments in my Facelets?

问题

I would like to remove all HTML comments from my facelets before delivering to end users. Does any standard approach exist?

回答1:

There are actually two ways:

1. To remove ALL comments, add this to web.xml:

   <context-param>
       <param-name>javax.faces.FACELETS_SKIP_COMMENTS</param-name>
       <param-value>true</param-value>
   </context-param>
   

   or when you're still on JSF 1.2 which doesn't use Facelets as default view technology yet:

   <context-param>
       <param-name>facelets.SKIP_COMMENTS</param-name>
       <param-value>true</param-value>
   </context-param>
   

2. To remove specific comments only, use <ui:remove>.

   <ui:remove><!-- This is a HTML comment. --></ui:remove>
