Spring Boot Oauth Custom Login Form - spring

Question

I followed the spring tutorial "SSO with OAuth2: Angular JS and Spring Security Part V".
I converted the "authserver"-project from maven to gradle after that the custom login form doesn't work anymore.
Are the wro tasks in the pom.xml needed for the login form to work?
I also tried this tutorial but it didn't work in my scenario either:
http://docs.spring.io/spring-security/site/docs/3.2.x/guides/form.html
I hope that you can help me.

Code in the OAuth2ServerConfiguration:
#Override
public void configure(HttpSecurity http) throws Exception {
http.formLogin().loginPage("/login").permitAll()
.and().requestMatchers()
.antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access")
.and().authorizeRequests()
.anyRequest().authenticated();
}
MainAuthserverApplication.java:
#ComponentScan
#SessionAttributes("authorizationRequest")
#EnableAutoConfiguration()
#EnableConfigurationProperties({AuthProperties.class})
public class MainAuthserverApplication extends WebMvcConfigurerAdapter {
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
registry.addViewController("/oauth/confirm_access").setViewName("authorize");
}

Answer 1

I already fixed the problem myself:
It seems that these two methods have to be in the same class:
#Configuration
#Order(-20)
protected static class LoginConfig extends WebSecurityConfigurerAdapter {
#Autowired
private AuthenticationManager authenticationManager;
#Override
protected void configure(HttpSecurity http) throws Exception {
// #formatter:off
http.formLogin().loginPage("/login").permitAll().and().requestMatchers()
.antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access").and().authorizeRequests()
.anyRequest().authenticated();
// #formatter:on
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.parentAuthenticationManager(authenticationManager);
}
}
