How to use api to pull up a oidc flow?

[mengxzh]

1. In Spring Security Samples, Its use /login page to authenticate and pull up a OAuth2 Authorization Code flow;
2. I want to use Customer Authentication and use OAuth2 Authorization code to complete OIDC; Like this, UsernamePassword is just a sample Authenticate in below code

   @RequestMapping("/login")
   public Authentication login() {
   UsernamePasswordToken unauthenticated = UsernamePasswordToken.unauthenticated("admin", "123456");
   Authentication authenticated = authenticationManager.authenticate(unauthenticated);
   // How to pull up a oauth2 authorization code with OAuth2AuthorizationEndpointFilter
   // may be no result, because OAuth2AuthorizationEndpointFilter redirect to OAuth2 client
   return authenticated;
   }

   May i need customer /oauth2/authorize request in /login request? In Default Config Spring Authorization Server, when authentication authenticated, its use last requestd to pull up Like

   /oauth2/authorize -> no authentication -> save current request -> usernamePasswordFilter -> redirect save last request 

   But i am use no session to complete this, how could i done it?
