ClassDescriptionAbstract base class for filename suffix based
VersionStrategyimplementations, for example, "static/myresource-version.js".Abstract base class forVersionStrategyimplementations that insert a prefix into the URL path, for example, "version/static/myresource.js".BaseResourceResolverproviding consistent logging.AResourceResolverthat resolves resources from aCacheor otherwise delegates to the resolver chain and caches the result.AResourceTransformerthat checks aCacheto see if a previously transformed resource exists in the cache and returns it if found, or otherwise delegates to the resolver chain and caches the result.AVersionStrategythat calculates a Hex MD5 hash from the content of the resource and appends it to the file name, for example,"styles/main-e36d2e05253c6c7085a91522ce43a0b4.css".AResourceTransformerimplementation that modifies links in a CSS file to match the public URL paths that should be exposed to clients (for example, with an MD5 content-based hash inserted in the URL).Abstract base class forCssLinkResourceTransformer.LinkParserimplementations.Extract content chunks that represent links.Resolver that delegates to the chain, and if a resource is found, it then attempts to find an encoded (for example, gzip, brotli) variant that is acceptable based on the "Accept-Encoding" request header.AVersionStrategythat relies on a fixed version applied as a request path prefix, for example, reduced SHA, version name, release date, etc.Extended interface for aResourceto be written to an HTTP response.AResourceResolverthat delegates to the chain to locate a resource and then attempts to find a matching versioned resource contained in a WebJar JAR file.Raised whenResourceWebHandleris mapped to the request but can not find a matching resource.A simpleResourceResolverthat tries to find a resource under the given locations matching to the request path.Resource handling utility methods to share common logic betweenResourceWebHandlerandorg.springframework.web.reactive.function.server.A strategy for resolving a request to a server-side resource.A contract for invoking a chain ofResourceResolverswhere each resolver is given a reference to the chain allowing it to delegate when necessary.An abstraction for transforming the content of a resource.A contract for invoking a chain ofResourceTransformerswhere each resolver is given a reference to the chain allowing it to delegate when necessary.A base class for aResourceTransformerwith an optional helper method for resolving public links within a transformed resource.A central component to use to obtain the public URL path that clients should use to access a static resource.HttpRequestHandlerthat serves static resources in an optimized way according to the guidelines of Page Speed, YSlow, etc.An extension ofByteArrayResourcethat aResourceTransformercan use to represent an original resource preserving all other information except the content.Resolves request paths containing a version string that can be used as part of an HTTP caching strategy in which a resource is cached with a date in the distant future (for example, 1 year) and cached until the version, and therefore the URL, is changed.A strategy to determine the version of a static resource and to apply and/or extract it from the URL path.
