Simple Websocket Proof of Concept

1) Sending message and receiving a reply. -> Explanation : > The browser should be able to send a message and recieve a reply back. > The respective reply should be recieved at the same browser window that sent it. Different windows(identified with unique id) should be able to send different messages and recieve different replies. > if they have the same id's, they both should recieve the reply. Browser window 1(W1) : Opened a socket with unique ID : 1 Browser window 2(W2) : Opened a socket with unique ID : 2 Browser window 3(W3) : Opened a socket with ID : 1 W1 sent a message, the reply should come back to 1 and 3 W2 sent a message, the reply should come back to 2 Example Message Sent by W1 : Hello. Example Message Recieved by W1 : Hello Sent by ID 1. Example Message Recieved by W3 : Hello Sent by ID 1. Example Message Sent by W2 : Hello. Example Message Recieved by W2 : Hello Sent by ID 2. 2) There should be a way to send a Message directly to a window associated with the ID. Explanation : > Let's say I can directly send a message to W2 if I know it is using id 2. This may be achieved by rest client, like Postman or ARC, not necessarily in need of a full blown application. Must use Spring boot 2.0 on the server side.
