java - Oauth2.0 auhtorization server configuration -

i'm creating protected rest apis based on oauth2.0 framework.

i built authorization server , resource server successfully.

the authorizationserver extends authorizationserverconfigureradapter , overrides methods, i'm facing problem extended method

public void configure(clientdetailsserviceconfigurer clients) throws exception {}

here explanation

when i'm running version of config() authorization server

    @override     public void configure(clientdetailsserviceconfigurer clients) throws exception {          clients.inmemory().withclient("clientapp").authorizedgranttypes("password", "refresh_token")                 .scopes("read", "write").resourceids(resource_id).secret("123456");     } 

this method works fine , returns access_token when ask it.

but when ran same method enhancements, got nothing when asked access_token 401 unauthorized http response.

    public void configure(clientdetailsserviceconfigurer clients) throws exception {     int n = appmetier.getappscount();     (app app:appmetier.findall(0, n).getapps()) {         clients.inmemory().withclient(app.getclientpublicid()).authorizedgranttypes("password", "refresh_token")                 .scopes("read", "write").resourceids(resource_id).secret(app.getclientsecretid());     }   } 

the n variable here equals 17, means have 17 clients in memory have right receive access_token.

the 1 gets access_token 17 first one.

your answers please , in advance.

you're calling inmemory() multiple times, overwrites builder service every time. should called once.

following code should work.

public void configure(clientdetailsserviceconfigurer clients) throws exception {     int n = appmetier.getappscount();     inmemoryclientdetailsservicebuilder clientbuilder = clients.inmemory();      (app app:appmetier.findall(0, n).getapps()) {         clientbuilder.withclient(app.getclientpublicid()).authorizedgranttypes("password", "refresh_token")             .scopes("read", "write").resourceids(resource_id).secret(app.getclientsecretid());     } }
