Here are just a few additional notes. In addition, Netty's support for the WebSocket protocol is much better th

what is websocket. WebSocket is a real-time technology for resolving server - side and client communication. Ajax can also communicate, but he can't do it in real time. We want real-time effects before websocket, all through polling, which is obviously a waste of resources. WebSocket's strength is that, compared to Ajax needs to initiate requests from the client

I believe that with the introduction in the previous two articles, developers who are a little familiar with socket programming should be able to design a websocket-based online interaction system on their own, while I am still somewhat enthusiastic about it, simply write a complete chat room, just a little contribution to the industry's new socket development. You are welcome to give me some ideas and Code. It is my wish to promote each other. Let's
