public class TreeWalkUriResolveStrategy

implements ContentUriResolveStrategy

Fallback for URIs which are not (yet) in the Node_url table: resolves a URI by walking the content tree from its domain along the path parts. Below a renamed or moved node, the Node_url entries are only updated by the periodic UpdateUrlIndexBatchJob (or not at all as long as it fails for a node, e.g. because of conflicting URLs). In the meantime, these nodes can only be resolved under their new URI by this strategy. Walking the tree needs several queries per URI, while PublicUriResolveStrategy needs a single lookup in the Node_url table. Therefore, this strategy only runs if that one found no exact match, which also applies to all URIs which do not exist (e.g. made-up or outdated URIs requested by crawlers below a known domain). Successful resolutions are logged to see how often and for which URIs it is needed. Resolved URIs are cached per instance, so a URI is logged again only after it was removed from that cache. It can be disabled by setting `nice2.dms.TreeWalkUriResolveStrategy.enabled=false`.
