org.springframework.web.servlet.resource.CssLinkResourceTransformer
A {@link ResourceTransformer} implementation that modifies links in a CSSfile to match the public URL paths that should be exposed to clients (e.g. with an MD5 content-based hash inserted in the URL).
The implementation looks for links in CSS {@code @import} statements andalso inside CSS {@code url()} functions. All links are then passed through the{@link ResourceResolverChain} and resolved relative to the location of thecontaining CSS file. If successfully resolved, the link is modified, otherwise the original link is preserved. @author Rossen Stoyanchev @since 4.1
