HandlerResult returned from a HandlerAdapter can expose a function for error handling based on some handler-specific mechanism. This error function is called if: • The handler (for example, @Controller) fails. • The handling of the handler return value through a HandlerResultHandler fails. The error function can change the response (for example, to an error status), as long as an error signal occurs before 1.5.1. Overview Web MVC In WebFlux.fn, an HTTP request is handled with a HandlerFunction: a function that takes ServerRequest and returns a delayed ServerResponse (i.e. Mono). Both

DispatcherServlet. 1.4.1. Overview WebFlux In WebMvc.fn, an HTTP request is handled with a HandlerFunction: a function that takes ServerRequest and returns a ServerResponse. Both the request and the response object routed to a handler function with a RouterFunction: a function that takes ServerRequest and returns an optional HandlerFunction (i.e. Optional). When the router function matches, a handler handler function is returned; otherwise an empty Optional. RouterFunction is the equivalent of a @RequestMapping annotation, but with the major difference that router functions provide not just data, but
