@Qualifier not picking up @Bean

Question

I am trying to follow this tutorial on setting up OAuth authentication in my web application I have just started, I am fairly new to spring and have been scratching my head over as to why the OAuth2AuthorisationServerConfig class cannot pick up the bean.

@Configuration
public class ServerSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("JL").password("TEST").roles("USER");
    }

    @Override
    @Bean //Here is the bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/", "/login", "/register").permitAll()
                .anyRequest().authenticated()
                .and().formLogin().permitAll()
                .and().logout().permitAll();
    }

}

@Configuration
public class OAuth2AuthorisationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    @Qualifier("authenticationManagerBean")  // here is the qualifier for bean
    private AuthenticationManager authenticationManager;
    ....
}

The two classes are in the same package

在OAuth2AuthorisationServerConfig类中，我已使用@ComponentScan对其进行了注释，这似乎已经解决了该问题。
