model. You can think of this as a small library or a set of utilities that an application can use to route and handle requests. The big difference with annotated controllers is that the application is in WebFlux includes WebFlux.fn, a lightweight functional programming model in which functions are used to route and handle requests and contracts are designed for immutability. It is an alternative to the annotation-based major difference that router functions provide not just data, but also behavior. RouterFunctions.route() provides a router builder that facilitates the creation of routers, as the following example shows:

whole. Message Format RSocket messages contain data and metadata. Metadata can be used to send a route, a security token, etc. Data and metadata can be formatted differently. Mime types for each are declared requests on a given connection. While all messages can have metadata, typically metadata such as a route are per-request and therefore only included in the first message on a request, i.e. with one of the applications: • Composite Metadata-- multiple, independently formatted metadata entries. • Routing — the route for a request. 1.2. Java Implementation The Java implementation for RSocket is built on Project

application is ready to handle traffic. A failing “Readiness” state tells the platform that it should not route traffic to the application for now. This typically happens during startup, while CommandLineRunner RequestPredicates.accept; import static org.springframework.web.servlet.function.RouterFunctions.route; @Configuration(proxyBeanMethods = false) public class MyRoutingConfiguration { private static public RouterFunction routerFunction(MyUserHandler userHandler) { return route() .GET("/{user}", ACCEPT_JSON, userHandler::getUser) .GET("/{user}/customers"
