Spring Security OAuth2 always redirects to /login page having a valid Bearer header

Question

I am having a hard time getting Spring Security OAuth2 to work. I am able to get a access_token from /oauth/token endpoint but accessing a protected resource with that token in header "Authorization: Bearer $TOKEN" always redirects me to /login. This is a complete REST API.

OAuth2Config

    @Configuration
public class OAuth2Configuration {

    private static final String SERVER_RESOURCE_ID = "oauth2-server";

    private static InMemoryTokenStore tokenStore = new InMemoryTokenStore();


    @Configuration
    @EnableResourceServer
    protected static class ResourceServer extends ResourceServerConfigurerAdapter {

        @Override
        public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
            resources.tokenStore(tokenStore).resourceId(SERVER_RESOURCE_ID);
        }

        @Override
        public void configure(HttpSecurity http) throws Exception {
            http.requestMatchers().antMatchers("/admin**").and().authorizeRequests().antMatchers("/admin**").access("#oauth2.hasScope('read')");
        }
    }

    @Configuration
    @EnableAuthorizationServer
    protected static class AuthConfig extends AuthorizationServerConfigurerAdapter {

        @Autowired
        private AuthenticationManager authenticationManager;


        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints.authenticationManager(authenticationManager).tokenStore(tokenStore).approvalStoreDisabled();
        }

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            clients.inMemory()
                .withClient("my-client")
                    .authorizedGrantTypes("authorization_code","refresh_token", "password")
                    .authorities("ROLE_CLIENT")
                    .scopes("read")
                    .resourceIds(SERVER_RESOURCE_ID)
                    .secret("secret")
            ;
        }
    }
}

SecurityConfig class

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        auth
                .userDetailsService(userDetailsService)
                .passwordEncoder(bCryptPasswordEncoder());

    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

Following are the debug logs

What is it that I am missing? I have almost tried every example over the web into my existing project but I am always redirected to the /login endpoint when I try to request a protected resource with a valid token.

Thanks.

Solution

So it turned out that since I was upgrading from an earlier version of spring boot to 1.5.2, in the release notes it is said that the order of the resource filter has been changed. See here. Just place this magic property in application.properties file and it fixes everything.

security.oauth2.resource.filter-order = 3

he default order of the OAuth2 resource filter has changed from 3 to SecurityProperties.ACCESS_OVERRIDE_ORDER - 1. This places it after the actuator endpoints but before the basic authentication filter chain. The default can be restored by setting security.oauth2.resource.filter-order = 3.

Thanks, I faced the same issue too (Spring 1.5.4), adding this helped reach the endpoint.
