public class WebJarsResourceResolver extends AbstractResourceResolver
ResourceResolver that delegates to the chain to locate a resource and then
attempts to find a matching versioned resource contained in a WebJar JAR file.
This allows WebJars.org users to write version agnostic paths in their templates,
like <script src="/jquery/jquery.min.js"/>.
This path will be resolved to the unique version <script src="/jquery/1.2.0/jquery.min.js"/>,
which is a better fit for HTTP caching and version management in applications.
This also resolves resources for version agnostic HTTP requests "GET /jquery/jquery.min.js".
This resolver requires the "org.webjars:webjars-locator" library on classpath, and is automatically registered if that library is present.
