spring - Request from html client: how will I know that requested user is logged in or not? -

-

here spring login handler

public class loginsuccesshandler extends savedrequestawareauthenticationsuccesshandler {      @override     public void onauthenticationsuccess(httpservletrequest request, httpservletresponse response, authentication authentication) {          httpsession session = request.getsession();         loggedinuser logginuserobj = (loggedinuser)authentication.getprincipal();         string userid = logginuserobj.getuserid();          session.setattribute("userid", userid);         session.setattribute("username", logginuserobj.getname());         session.setattribute("hasphoto", user.getproperty(uservertex.profilephotouploaded.tostring()));         if(logginuserobj.getactivatelink()!=null)             session.setattribute("activatelink", logginuserobj.getactivatelink());          try {             object referurl = session.getattribute("referer_url");             if(referurl != null){                 session.removeattribute("referer_url");                 response.sendredirect(referurl.tostring());             }             else                 response.sendredirect("profile/"+userid);         } catch (ioexception ex) {             logger.error(ex);         }        }     }

my client in plain html, jquery (in cordova). question if everytime user makes request, how know requested user logged in or not ?

e.g. here sample :

$.ajax({   url: "addnewpost",   data:{} })

here loggedin user can add new post. when calling addnewpost rest service in spring @restcontroller how know request logged in user ?

since you're using success handler before request goes success handler goes authentication manager.in authentication manager if have configured authentication provider there authenticity of user check , if returns success call go onauthenticationsuccess.in authentication provider values in request header depending upon type of authentication provider using.if missing user not logged in.here better picture 1 example(here checking authorization admin) enter image description here

you can refer link

hope gives clear picture!!

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
