 ResourceResolverChain chain)

Description copied from interface: ResourceResolver

Resolve the supplied request and request path to a Resource that exists under one of the given resource locations.

Specified by:

resolveResource in interface ResourceResolver

Parameters:

exchange - the current exchange

requestPath - the portion of the request path to use. This is expected to be the encoded path, i.e. PathContainer.value().

locations - the locations to search in when looking up resources

chain - the chain of remaining resolvers to delegate to

Returns:

the resolved resource or an empty Mono if unresolved

resolveUrlPath

public reactor.core.publisher.Mono<String> resolveUrlPath(String resourceUrlPath,
 List<? extends Resource> locations,
 ResourceResolverChain chain)

Description copied from interface: ResourceResolver

Resolve the externally facing public URL path for clients to use to access the resource that is located at the given internal resource path.

This is useful when rendering URL links to clients.

Specified by:

resolveUrlPath in interface ResourceResolver

Parameters:

resourceUrlPath - the "internal" resource path to resolve a path for public use. This is expected to be the encoded path.

locations - the locations to search in when looking up resources

chain - the chain of resolvers to delegate to

Returns:

the resolved public URL path or an empty Mono if unresolved

resolveResourceInternal

protected abstract reactor.core.publisher.Mono<Resource> resolveResourceInternal(@Nullable
 ServerWebExchange exchange,
 String requestPath,
 List<? extends Resource> locations,
 ResourceResolverChain chain)

resolveUrlPathInternal

protected abstract reactor.core.publisher.Mono<String> resolveUrlPathInternal(String resourceUrlPath,
 List<? extends Resource> locations,
 ResourceResolverChain chain)
