@Deprecated(forRemoval=true)
public class WebJarsResourceResolver
extends AbstractResourceResolver

Deprecated, for removal: This API element is subject to removal in a future version.

as of Spring Framework 6.2 in favor of LiteWebJarsResourceResolver

A 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="/webjars/jquery/jquery.min.js"/>. This path will be resolved to the unique version <script src="/webjars/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-core library on the classpath and is automatically registered if that library is present.

Be aware that WebJarAssetLocator constructor performs a classpath scanning that could slow down application startup.

Since:

4.2
