Question! Since this is a WebSocket, can multiple clients connect to it? If yes, if I run localhost:8091 on one browser and another instance on a different browser, would they share the same WebSocket? And would I see the Hi messages shared on both the browsers?
Bro, How can i send message to a particular client from server. In this senario how many are connected in the server, message got everyone, how we can prevent that
Hi I am trying this same example..but when I have the ui running as the client in port 8082 and the microservice and websocket configuration running in 8084..during connect websocket from 8082 it's opening websocket and failing for cross origin..I have tried adding set allowed origin as * in websocket configuration ..still not working.. any idea or suggestion for when the client and the service running in different url?
jquery is not loading directly from latest webjars, so change reference to jquery.min.js in index.html file. And Forgot min.css we don't have that file in repo :)
Useful video. Thank you so much. I have one doubt. We will use Http connection to hit the rest API and it will be processed in a thread for each request. Just like rest, will there be any thread are created for webscoket which will be listening? And how to manage the pool size for http and websocket.? Is this websocket a good option to use in production instead of using http long polling? Since there will be many clients connection ,is it a burden on the server?
Hi, I am new websockets and I understand it helps client and server to establish full duplex communication and active connection. Can I think of having a websocket server act as an interface to establish communication between two different clients? Client A(listens to receive)- Websocket Server - Client B(sends)
Good Learning . can you provide location look up service example from google api with cache we have zip code and want longitude and latitude .and this look up service can be access globally by multiple service
@@blasttrash I think you can trigger the controller which has message mapping with scheduler and be able to modifying and sending a json object of your models. It is only the idea.
You can either do it in parallel or in sequence, but you need to make sure transactionality is handled correctly. eg, What if DB update fails, do u need to dequeue the message? likewise the reverse.
I found a solution in the link below but i did not try it myself. May be it helps you. If it works can you send me a feedback please? stackoverflow.com/questions/41186737/how-connect-android-device-to-spring-websocket-server
REST is for point to point communication. WebSockets are used when you need your communication channel to be always open. like the example i showed in my intro video on Websockets
Great Tutorial. Everything build from scratch, very nice! Congratulations.
Thanks for explanation. It really help in my current POC.
Nice one. You are doing a great job mate
Awesome article. Kudos to you. 👍
Thanks for explaining everything, really helpfull!

In Spring 2.1.2 AbstractWebSocketMessageBrokerConfigurer is deprecated. So what is it's equivalent in 2.x??
Now there is a interface WebSocketMessageBrokerConfigurer. You have to implement this interface.
Hello sir , do I need to do any extra setup for connections originating from android/iOS ?? Kindly suggest asap

Client A(listens to receive)- Websocket Server - Client B(sends)
You can. However if it's the same channel, then clientB also recieves the same message which it published to server
Tech Primers Thanks. Can you share some references pls?
Can you give video for apache http server with wesocket reverse proxy
Sir can't we separate the front-end ? Using @RestController ...
I want to build the same but I want my frontend to be on separate port
Plz help 😔
Good Learning . can you provide location look up service example from google api with cache
we have zip code and want longitude and latitude .and this look up service can be access globally by multiple service
Good tutorial. Can you please provide a chat application using web socket.
sure
thank you very much!!!
I have a bug:
Websocket-example/info not found(404)
Please help
could you show me sending messages from postman once
How do i send JSON data from the server side?
were u able to figure it out?
@@blasttrash I think you can trigger the controller which has message mapping with scheduler and be able to modifying and sending a json object of your models. It is only the idea.
Also then why we go for JMS?
In websockets, you need the consumer/producer to be always UP to establish a connection. in an event driven system, you don't have to worry about that
How can i push message into queue while a db modification happens? Without scheduler.
You can either do it in parallel or in sequence, but you need to make sure transactionality is handled correctly. eg, What if DB update fails, do u need to dequeue the message? likewise the reverse.
@@TechPrimers Likewise or Otherwise if a transaction fails. Why the hell he is going to push and of course no one is going to have the attention
He has just copy-pasted the official tutorial from Spring web-site with some small modifications.
Well! Almost 90% of programming is using some original source with small modifications :-D
Do you have unit test for it?
nope mate
how can I send to one user like chat rooms???????????????????????????
I want hint plz
Please can anyone tell how to listen for this spring WebSocket server from android app

SocketJS cliente java . Como se hace?
Thanks a lot ajay.. chat app(group chat)?
sure. will do
Thank you very MUCH for the video #SMASH_LIKE
Not working.
Why rest is more popular than web socket then? Using web socket also we can achieve what ever is achieving using rest.
REST is for point to point communication. WebSockets are used when you need your communication channel to be always open. like the example i showed in my intro video on Websockets
issue
when i refresh page websocket disconnect automatically
can any one tell me please why disconnect websocket???
This is because the websocket cannot be alive if either server/client is down. so if u refresh, the connection needs to be re-established
Thanks, is there any way for established connection on refresh web browser page?
Any helpful material ?
yes, nice only when you understand your code in js. otherwise it is not very usefull.
Timewaste
Thank you very much!!!
