Spring Webflux supports a number of servers, as follows:

• Netty
• Jetty

RouterFunctions.toHttpHandler(RouterFunction)

If you want to run the previously created RouterFunction in Netty, the following code snippet can be used:

HttpHandler httpHandler = RouterFunctions.toHttpHandler(movieRoutes);ReactorHttpHandlerAdapter reactorAdapter = new ReactorHttpHandlerAdapter(httpHandler);HttpServer server = HttpServer.create(HOST, ...
