Spring Boot + AngularJS + Handle login attemps -


i've followed authenticationfailurebadcredentialsevent - how distinguish between bad password or bad username? creating app. don't understand how login in; it's working far.

i need now, implement logic login attemps. simple "if try login account , fail password 10 times, i'll block user".

here's config custom userdetailsservice implementation:

@autowired public void configureglobal(authenticationmanagerbuilder auth) throws exception {      auth         .userdetailsservice(userdetailsservice)         .passwordencoder(passwordencoder);  }

customuserdetailsservice overriden loadbyusername function:

@override public userdetails loaduserbyusername(final string login) {      user user = userrepository.findbyemail(login);      if (user == null) {         throw new usernamenotfoundexception(login);     }     return new user(user.getemail(), user.getpassword(), getauthorities(user.getrole())); }

so far i've tried:

1) implement authenticationfailurebadcredentialsevent. works fine, can't distinguish if exception because of user not found, or password wrong, same this

2) implement customauthenticationprovider adding auth.authenticationprovider(customauthenticationprovider) in configureglobal method, couldn't use customuserdetailsservice.

3) implement authenticationfailurehandler works withing formlogin , not "ajax authentication spring-boot + angularjs example".

any clues on this?

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...

during login process of laravel spark need request token of remote api. api stores exact same users , passwords laravel spark application. therefore need username , non hashed password of user during authentication process. i thought overriding authenticated method solution problem. in routes/web.php override post /login endpoint , pointing endpoint own logincontroller: <?php namespace app\http\controllers\auth; use illuminate\support\facades\log; use illuminate\http\request; use laravel\spark\http\controllers\auth\logincontroller sparklogincontroller; class logincontroller extends sparklogincontroller { /** * create new login controller instance. * * @return void */ public function __construct() { parent::__construct(); } /** * handle successful authentication attempt. * * @param request $request * @param \illuminate\contracts\auth\authenticatable $user * @return response */ public fu...
