WebSocket sample Java is relatively small, mostly Nodejs, more famous is Socket.io's chat,

Borrow his front-end to implement a set of Java, the backend based on the Nimbleio implementation of WebSocket writing,

Directly on the code:

 Public voidAccept (Session session, Readfuture future)throwsException {if(Futureinstanceofhttpreadfuture) {            Super. Accept (Session, future); return; } websocketreadfuture F=(websocketreadfuture) future; //CLOSE        if(F.gettype () = = 8) {msgadapter.removeclient (session); Jsonobject obj=NewJsonobject (); Obj.put ("Username", Session.getattribute ("username")); Obj.put ("Numusers", Msgadapter.getclientsize ()); Obj.put ("Action", "User-left"); String MSG1=obj.tojsonstring ();                    Msgadapter.sendmsg (MSG1); } Else {//String msg = getmsg (session,);String msg=f.getdata (). toString (Encoding.UTF8); Jsonobject obj=jsonobject.parseobject (msg); String Action= obj.getstring ("Action"); if("New-message". Equals (action)) {Obj.put ("Username", Session.getattribute ("username")); String MSG1=obj.tojsonstring ();                            Msgadapter.sendmsg (MSG1); }Else if("Add-user". Equals (action))                                {Msgadapter.addclient (session); String username= (String) session.getattribute ("username"); if(Username! =NULL){                    return; } username= Obj.getstring ("username"); Session.setattribute ("Username", username); Obj.put ("Numusers", Msgadapter.getclientsize ()); Obj.put ("Action", "login"); String MSG1=obj.tojsonstring (); Websocketreadfutureimpl F2=NewWebsockettextreadfutureimpl ();                F2.write (MSG1);                                Session.flush (F2); Obj.put ("Username", username); Obj.put ("Action", "user-joined"); String MSG2=obj.tojsonstring ();                            Msgadapter.sendmsg (MSG2); }Else if("Typing". Equals (action)) {Obj.put ("Username", Session.getattribute ("username")); String MSG1=obj.tojsonstring ();                                            Msgadapter.sendmsg (MSG1); }Else if("Stop-typing". Equals (action)) {Obj.put ("Username", Session.getattribute ("username")); String MSG1=obj.tojsonstring ();                            Msgadapter.sendmsg (MSG1); }Else if("Disconnect".
