How to use Spring ResourceUrlEncodingFilter with velocity template

Question

Spring boot docs suggest that velocity templates have support for ResourceUrlEncodingFilter for rewriting static assets url with versioning. Quote from the docs:

Links to resources are rewritten at runtime in template, thanks to a ResourceUrlEncodingFilter, auto-configured for Thymeleaf, Velocity and FreeMarker.

I found out from this blog the syntax for thymeleaf for url rewriting. But after spending a couple of hours of google searching I wasn't able to find the syntax or macros for Velocity templating language. Can anyone point me to a resource which explains this.

This is a bug, see SPR-14027 . In the meantime, you can define your own macro like this:

#macro( springResourceUrl $relativeUrl )$springMacroRequestContext.getContextUrl(${relativeUrl})#end

And call it like this:

<script src="#springResourceUrl("/script.js")"></script>

Note that Velocity support is deprecated as of Spring 4.3 (see SPR-13235 ) and should be removed in Spring 5.0 (see SPR-13795 ).
