org.springframework.web.servlet.resource.CachingResourceTransformer
A {@link org.springframework.web.servlet.resource.ResourceTransformer} that checks a{@link org.springframework.cache.Cache} to see if a previously transformed resourceexists in the cache and returns it if found, and otherwise delegates to the resolver chain and saves the result in the cache. @author Rossen Stoyanchev @since 4.1


  public ResourceChainRegistration(boolean cacheResources, Cache cache) {
    Assert.isTrue(!cacheResources || cache != null, "'cache' is required when cacheResources=true");
    if (cacheResources) {
      this.resolvers.add(new CachingResourceResolver(cache));
      this.transformers.add(new CachingResourceTransformer(cache));
    }
