Spring does not serve static files with unknown extensions

Question

I use tag <mvc:resources .../> to map static content. Everything works fine until I try to access a file with an unknown file extension, for example, some * .less file. When I try to access a file with this extension, I get 404 error. If I change the file extension, for example. * .css, it works great. If I don't use <mvc:resources .../> and map the default servlet to static content, there is no problem either.

Do you know how to fix this? Thanks in advance.

Do you use Tomcat? If so, try adding the mime-mapping element to web.xml :

 <mime-mapping> <extension>less</extension> <mime-type>text/plain</mime-type> <!-- Or whatever. --> </mime-mapping>
