Spring Security OAuth2 clientId and clientSecret -


i evaluating spring security oauth2 implementation. confused clientid , clientsecret.

i follow https://spring.io/guides/tutorials/spring-security-and-angular-js/ build auth server.

i can generate code 

http://localhost:9999/uaa/oauth/authorize?response_type=code&client_id=acme&redirect_uri=http://example.com

i can obtain accesstoken by

curl acme:acmesecret@localhost:9999/uaa/oauth/token  \ -d grant_type=authorization_code -d client_id=acme     \ -d redirect_uri=http://example.com -d code=jywioi {"access_token":"2219199c-966e-4466-8b7e-12bb9038c9bb","token_type":"bearer","refresh_token":"d193caf4-5643-4988-9a4a-1c03c9d657aa","expires_in":43199,"scope":"openid"}

when getting access token, clientid , clientsecret required.

but if have multiple clients, should start multiple auth server? cannot work in way.

how build oauth2 server without clientid , clientsecret?

the code here: https://github.com/yigubigu/spring-security-auth

you can setup may clients

ex in memory :- 

        public void configure(clientdetailsserviceconfigurer clients) throws exception {         clients.inmemory()                 .withclient("acme")                 .secret("acmesecret")                 .authorizedgranttypes("authorization_code", "refresh_token",                         "password").scopes("openid")                 .and()                 .withclient("xx")                 .secret("xx")                 .authorizedgranttypes("xxx");     }

or can add database record client

ref - spring oauth2 db schema

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
