Spring OAuth: Custom form for authenticating authorization endpoint - spring

Question

How can I set up a custom login form to protect my /oauth/authorize endpoint in an Spring Boot Application that is both a Authorization and Resource Server? I want to achieve that a user has to log in to make requests to /oauth/authorize. All resources, that are not /login and /oauth/** should be handled as secured resources protected by OAuth (requiring a valid access token)
So when a user calls localhost:1234/oauth/authorize?client_id=client&response_type=token&redirect_uri=http://localhost:5678 he is first redirected to the login form and after successfully loggin in redirect to the /oauth/authorize endpoint where the implicit OAuth flow proceeds.
When I try the following it works, using the standard basic authentication popup window
#Configuration
#EnableAuthorizationServer
public class OAuthConfig extends AuthorizationServerConfigurerAdapter {
#Autowired
private AuthenticationManager authenticationManager;
#Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager);
}
#Override
public void configure(final ClientDetailsServiceConfigurer clients)
throws Exception {
clients.inMemory()
.withClient("client")
.authorizedGrantTypes("implicit", "refresh_token")
.scopes("read");
}
}
The Resource config
#Configuration
#EnableResourceServer
public class ResourceConfiguration
extends ResourceServerConfigurerAdapter
{
#Override
public void configure(final HttpSecurity http) throws Exception {
// #formatter:off
http.authorizeRequests().antMatchers("/login").permitAll().and()
.authorizeRequests().anyRequest().authenticated();
// #formatter:on
}
}
The Web Security config
#Configuration
public class WebSecurityConfiguration
extends WebSecurityConfigurerAdapter
{
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/oauth/authorize").authenticated().and()
.authorizeRequests().anyRequest().permitAll().and().httpBasic();
}
}
but as soon as I replace httpBasic() with the following it fails:
#Configuration
public class WebSecurityConfiguration
extends WebSecurityConfigurerAdapter
{
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/oauth/authorize").authenticated().and()
.authorizeRequests().anyRequest().permitAll().and().formLogin().loginPage("/login").and().csrf()
.disable();
}
}
and my POST from the login Page is not redirected, it always just returns to /login
The output from the console is as following

Answer 1

Adding an #Order(-10) to the WebSecurityConfig resolves the issue. I think this annoation ensures that the WebSecurityConfig is used before the ResourceConfig. My final configuration looks like this:
#Configuration
#Order(-10)
public class WebSecurityConfig
extends WebSecurityConfigurerAdapter
{
#Autowired
private AuthenticationManager authenticationManager;
#Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.parentAuthenticationManager(authenticationManager);
}
#Override
protected void configure(HttpSecurity http) throws Exception {
// #formatter:off
http.authorizeRequests().antMatchers("/oauth/authorize").authenticated()
.and()
.authorizeRequests().anyRequest().permitAll()
.and()
.formLogin().loginPage("/login").permitAll()
.and()
.csrf().disable();
// #formatter:on
}
}
