Request 'OPTIONS /logout' doesn't match 'POST /logout

I am studying Spring Cloud and Spring OAuth2 by decomposing the three interconnected apps in this GitHub sample. When I open up the /oauth/revoke-token endpoint in the authserver app and then call it from the ui app with a http://localhost:9999/uaa/logout, the debug log for the authserver app gives the following error message while rejecting the logout request:

Request 'OPTIONS /logout' doesn't match 'POST /logout

What specific changes need to be made to the code in the sample GitHub apps in order to enable the global logout to succeed when the ui app calls the logout function from hello.js?

INITIAL EFFORTS:

Changes that I made so far include:

Add the following @Bean definition to AuthserverApplication.java: 

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

Add the following controller class in the demo package of the authserver app: 

@Configuration
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    TokenStore tokenStore;

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

    @RequestMapping(value = "/oauth/revoke-token", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public void logout(HttpServletRequest request) {
        String authHeader = request.getHeader("Authorization");
        if (authHeader != null) {
            String tokenValue = authHeader.replace("Bearer", "").trim();
            OAuth2AccessToken accessToken = tokenStore.readAccessToken(tokenValue);
            tokenStore.removeAccessToken(accessToken);
        }
    }
}

Change the logout() method of hello.js in the ui app to become the following: 

self.logout = function() {
    $http.post('http://localhost:9999/uaa/logout', {}).finally(function() {
        $rootScope.authenticated = false;
        $location.path("/");
    });
}

But when the user clicks on the logout button in the browser and triggers the call to http://localhost:9999/uaa/logout, the debug log for the authserver app gives the following output:

What other specific code changes need to be changed in the GitHub sample apps to enable the ui app to trigger a global logout of the user from all apps?

Note: Obviously, /uaa/logout is a different URL than /oauth/revoke-token. However, the inner workings of Spring Security and OAuth in this situation are not clear without an answer to this OP.

@StuXnet's Suggestions:

The content of the Firefox Developer Tools Network Tab for the request is:

The request to http : // localhost:9999/uaa/login with method OPTIONS was rejected with a 403 error.

The raw request headers were: 

Host: localhost:9999
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Origin: http://localhost:8080
Access-Control-Request-Method: POST
Access-Control-Request-Headers: content-type,x-requested-with
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache

The raw response headers were: 

Allow: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH
Content-Length: 20
Date: Mon, 18 Apr 2016 23:45:46 GMT
Server: Apache-Coyote/1.1
X-Application-Context: application:9999

Next, I changed the config(http) method of LoginConfig to read as follows: 

@Override
protected void configure(HttpSecurity http) throws Exception {
    // @formatter:off
    http
        .formLogin().loginPage("/login").permitAll()
        .and()
        .requestMatchers().antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access", "/logout", "/oauth/revoke-token")
        .and()
        .authorizeRequests()
        .antMatchers(HttpMethod.OPTIONS,"/logout").permitAll()
        .anyRequest().authenticated();
        // @formatter:on
}

This resulted in the following new printout in the Spring Boot DEBUG logs:

And the following request header in Firefox:

I then tried changing the configure(http) method of LoginConfig to become: 

@Override
protected void configure(HttpSecurity http) throws Exception {
    // @formatter:off
    http
        .formLogin().loginPage("/login").permitAll()
        .and()
        .requestMatchers().antMatchers("/login", "/oauth/authorize", "/oauth/confirm_access", "/logout", "/oauth/revoke-token")
        .and()
        .authorizeRequests()
        .anyRequest().authenticated()
        // @formatter:on
        .and()
        .csrf()
        .ignoringAntMatchers("/logout");
}

But the result is the following Spring Boot DEBUG log for the authserver app:

REPRODUCING THE PROBLEM ON YOUR MACHINE:

To reproduce the problem on your own machine, you can either:

1.) git clone the original sample app at the link at the top of the OP and then make the changes shown above, or

2.) Download the zipped version of the app as it exists on my devbox including all the changes from the OP at this file sharing link, and then:

2.a.) Untar the app.

2.b.) Navigate a terminal window to oauth2/resource and mvn spring-boot:run. Then navigate a second terminal window to oauth2/authserver and type mvn spring-boot:run. Then navigate a third terminal window to oauth2/ui and type mvn spring-boot:run.

2.c.) Navigate the web browser to http : // localhost:8080, then click login, then enter user for username and password for password. After you have been authenticated, click the logout button to reproduce the 403 error. Use the Network tab of your browser's developer tools to examine the browser activity. View the Spring Boot logs in the terminal that is running the authserver app to see Spring's activity.

3.) Either import the three folders into eclipse (or another IDE) as existing maven projects, or open the code files with a text editor to edit before repeating the relaunch and retesting in step 2.

What else can I provide to help isolate the solution?

Leaving aside the question of why you might want to do this and whether or not it is a good idea: your JS client is POSTing to an endpoint on another server, so you face two problems: Cross-Origin Resource Sharing (CORS) and Cross Site Request Forgery (CSRF), both of which are locked down by default in your Auth Server because it is using Spring MVC and Spring Security.

The CORS problem can be worked around in various ways, including the approach that you took, which was to punch a hole through the security configuration using a request matcher are permitAll(). There is a far better integration between Spring MVC and Spring Security using HttpSecurity.cors(). User guide link: http://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors. Simple example from the tutorial (vanilla resource server):

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors()
        ...;
}

What this does is switch on integration with the MVC declared endpoints with @CrossOrigin. Actually the endpoint you are trying to POST to is not one that you wrote, and it's not a Spring MVC endpoint, so you might have to use cors().configurationSource(...) instead.

The CSRF problem is also easy to solve in various different ways. The tutorial where you started has explicit examples showing how to do it for Angular JS (but not in the app you are using because the tutorial is not about logging out from the SSO provider). In that case we use the HttpSecurity.csrf() features. User guide link: http://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#csrf. Simple example from the tutorial in the UI app:

@Override
public void configure(HttpSecurity http) throws Exception {
    http
        ...
        .csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
}
