security - Concurrent user Login in spring mvc -

-

I currently have a problem implementing concurrent user sessions in Spring MVC. My requirement is that "I have a web application that uses Spring MVC, and I have my own entry form and I have not implemented spring protection yet (meaning that I have my web application No role-based user restriction is configured in). Only one user with the same username to log in from a machine.

My requirement:

  • One user per session
    • I have surfed, but no useful links or project
  • There is no role-based restriction
  • Once your own login form and user is logged in, the user object (containing the username is password) is stored in the session object
  • If user logs a second time If the user tries, the previous user session should be terminated and new users (other users) should be allowed on the home page.

    • Can a Solution, Link or Example Project Provide? Many thanks in advance :)

    Why not just go ahead and use spring protection? This will take care of passive sessions for you, you can use your own login form and you can not restrict any of your last points based on roles.

    You can configure the maximum number of sessions:

    c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

    -
    We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

    c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

    -
    I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
