Spring Oauth2 Authorization Server

Question

I setting the Spring Configuration Below:

@EnableAuthorizationServer
@EnableWebSecurity
@Configuration
public class Oauth2Provider extends WebSecurityConfigurerA         


        

Answer 1

To use password grant you need to provide an authentication manager to the authorization server (in the empty method with the TODO in your example), so it can authenticate users. If it's a Spring Boot application there is always an AuthenticationManager available to be @Autowired.
