Central entry point to Spring's functional web framework. Exposes routing functionality, such as to create a RouterFunction using a discoverable builder-style API, to create a RouterFunction given a RequestPredicate and HandlerFunction, and to do further subrouting on an existing routing function.

Method Summary

Modifier and Type	Method and Description
public static < the type of response returned by the handler function T extends ServerResponse> RouterFunction<T>	Returns: the change router function changeParser(RouterFunction<T> the router function to change the parser in routerFunction, PathPatternParser the parser to change to. parser) Changes the `PathPatternParser` on the given router function.
public static < the type of response returned by the handler function T extends ServerResponse> RouterFunction<T>	Returns: a router function that routes to `routerFunction` if `predicate` evaluates to `true` nest(RequestPredicate the predicate to test predicate, RouterFunction<T> the nested router function to delegate to if the predicate applies routerFunction) Route to the given router function if the given request predicate applies.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to a resource resource(RequestPredicate predicate to match predicate, Resource the resources to serve resource) Route requests that match the given predicate to the given resource.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to a resource resource(RequestPredicate predicate to match predicate, Resource the resources to serve resource, BiConsumer<Resource, HttpHeaders> provides access to the HTTP headers for served resources headersConsumer) Route requests that match the given predicate to the given resource.
public static Function<ServerRequest, Optional<Resource>>	Returns: the default resource lookup function for the given parameters. resourceLookupFunction(String the pattern to match pattern, Resource the location directory relative to which resources should be resolved location) Returns the resource lookup function used by `resources(String, Resource)`.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to resources resources(String the pattern to match pattern, Resource the location directory relative to which resources should be resolved location) Route requests that match the given pattern to resources relative to the given root location.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to resources resources(String the pattern to match pattern, Resource the location directory relative to which resources should be resolved location, BiConsumer<Resource, HttpHeaders> provides access to the HTTP headers for served resources headersConsumer) Route requests that match the given pattern to resources relative to the given root location.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to resources resources(Function<ServerRequest, Optional<Resource>> the function to provide a `Resource` given the `ServerRequest` lookupFunction) Route to resources using the provided lookup function.
public static RouterFunction<ServerResponse>	Returns: a router function that routes to resources resources(Function<ServerRequest, Optional<Resource>> the function to provide a `Resource` given the `ServerRequest` lookupFunction, BiConsumer<Resource, HttpHeaders> provides access to the HTTP headers for served resources headersConsumer) Route to resources using the provided lookup function.
public static RouterFunctions.Builder	Returns: a router function builder route() Offers a discoverable way to create router functions through a builder-style interface.
public static < the type of response returned by the handler function T extends ServerResponse> RouterFunction<T>	Returns: a router function that routes to `handlerFunction` if `predicate` evaluates to `true` route(RequestPredicate the predicate to test predicate, HandlerFunction<T> the handler function to route to if the predicate applies handlerFunction) Route to the given handler function if the given request predicate applies.
