Class AppCacheManifestTransformer

java.lang.Object

org.springframework.web.reactive.resource.ResourceTransformerSupport

org.springframework.web.reactive.resource.AppCacheManifestTransformer

All Implemented Interfaces:

ResourceTransformer

Deprecated.

as of 5.3 since browser support is going away

@Deprecated
public class AppCacheManifestTransformer
extends ResourceTransformerSupport

A ResourceTransformer HTML5 AppCache manifests.

This transformer:

• modifies links to match the public URL paths that should be exposed to clients, using configured ResourceResolver strategies
• appends a comment in the manifest, containing a Hash (e.g. "# Hash: 9de0f09ed7caf84e885f1f0f11c7e326"), thus changing the content of the manifest in order to trigger an appcache reload in the browser.

All files with an ".appcache" file extension (or the extension given to the constructor) will be transformed by this class. The hash is computed using the content of the appcache manifest so that changes in the manifest should invalidate the browser cache. This should also work with changes in referenced resources whose links are also versioned.

Since:

5.0
