This article mainly introduces "how to realize the SocketD protocol message subscription model". In the daily operation, I believe many people have doubts about how to realize the SocketD protocol message subscription model. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to realize the SocketD protocol message subscription model". Next, please follow the editor to study!

SocketD is a binary point-to-point communication protocol and a new network communication layer 7 protocol. Designed to be used in distributed applications. In this sense, SocketD can be an alternative to other similar protocols such as RSocket. Its message protocol specification has the characteristics of asynchronism, two-way back pressure, multiplexing, disconnection reconnection, message-based and so on. Only Java implementation is provided for the time being, and it is currently used as the sockte channel protocol for Solon rpc.

This case takes a simple message subscription model as an example: (that is, waiting for you to write to me, such as notification of changes to the configuration service)

Server / / start server public class ServerApp {public static void main (String [] args) {/ / launch Solon container (SocketD bean&plugin is managed by solon container) Solon.start (ServerApp.class, args, app-> app.enableSocketD (true)) }} / / define a tool public class SessionUtil {public static void broadcast (Message message) {for (Session session: SessionManager.socket (). GetOpenSessions ()) {session.send (message);}} public static void broadcast (String message) {for (Session session: SessionManager.socket (). GetOpenSessions ()) {session.send (message) } / / broadcast (e.g. configuration service update notification) SessionUtil.broadcast ("Hello client!") where needed; client / / launch client public class ClientApp {public static void main (String [] args) throws Throwable {/ / launch Solon container (SocketD bean&plugin is managed by solon container) Solon.start (ClientApp.class, args) } @ ClientEndpoint (uri = "tcp://localhost:28080") public class ClientListener implements Listener {@ Override public void onMessage (Session session, Message message) {/ / received the message, business processing System.out.println ("client: I received:" + message);}} at this point, the study on "how to implement the SocketD protocol message subscription model" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
