Spring Security OAuth2はRESTサービスでアクセスを拒否されます

SpringセキュリティとOAuth2を使用してSpring RESTサービスを保護しようとしています。私はなんとかトークンを手に入れました：

トークン

しかし、安全な休憩サービスを取得しようとすると、アクセスが拒否されます。

拒否された

なぜこれが起こっているのか誰かに教えてもらえますか？

AuthorizationServerConfig：

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    private static String REALM="EXAMPLE_REALM";

    @Autowired
    private TokenStore tokenStore;

    @Autowired
    private UserApprovalHandler handler;

    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authManager;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {

        clients.inMemory()
            .withClient("myRestClient") // client id
            .authorizedGrantTypes("password", "authorization_code", "refresh_token", "implicit")
            .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT")
            .scopes("read", "write", "trust")
            .secret("{noop}P@ssw0rd")
            .accessTokenValiditySeconds(240).//invalid after 4 minutes.
            refreshTokenValiditySeconds(600);//refresh after 10 minutes.
    }

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

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.realm(REALM+"/client");
    }

}

ResourceServerConfig：

@Configuration
@EnableResourceServer

public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    private static final String RESOURCE_ID = "SPRING_REST_API";

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.resourceId(RESOURCE_ID).stateless(false);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.
        anonymous().disable()
        .requestMatchers().antMatchers("/api/**")
        .and().authorizeRequests()
        .antMatchers("/api/**").access("hasRole('ADMIN')")
        .and().exceptionHandling().accessDeniedHandler(new OAuth2AccessDeniedHandler());
    }

}

SecurityConfig：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private ClientDetailsService clientService;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return PasswordEncoderFactories.createDelegatingPasswordEncoder();
    }
    @Override
    protected void configure(final AuthenticationManagerBuilder auth) throws Exception{        
        auth
            .inMemoryAuthentication()
                .withUser("user")
                .password(passwordEncoder().encode("password"))
                .roles("USER")
            .and()
                .withUser("admin")
                .password(passwordEncoder().encode("admin"))
                .roles("ADMIN");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .csrf().disable()
        .anonymous().disable()
        .authorizeRequests()
        .antMatchers("/oauth/token").permitAll()
        .antMatchers("/about").authenticated();
    }

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


    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

    @Bean
    @Autowired
    public TokenStoreUserApprovalHandler userApprovalHandler(TokenStore tokenStore){
        TokenStoreUserApprovalHandler handler = new TokenStoreUserApprovalHandler();
        handler.setTokenStore(tokenStore);
        handler.setRequestFactory(new DefaultOAuth2RequestFactory(clientService));
        handler.setClientDetailsService(clientService);
        return handler;
    }

    @Bean
    @Autowired
    public ApprovalStore approvalStore(TokenStore tokenStore) throws Exception {
        TokenApprovalStore store = new TokenApprovalStore();
        store.setTokenStore(tokenStore);
        return store;
    }

}

AboutController（レストサービス）：

    @RestController
public class AboutController {
    @RequestMapping(value = "/about", method = RequestMethod.GET)
    public ResponseEntity<?> home() {
        return new ResponseEntity<>("This is a demo application to show how to secure REST API using Spring Security and OAuth2", HttpStatus.OK);
    }
}

application.properties：

server.servlet.context-path=/api
security.oauth2.resource.filter-order = 3
