Ich arbeite mit einem Tutorial, das beschreibt, wie man eine einfache einseitige App mit Spring Boot, Spring Security und AngularJS schreibt:https: //spring.io/guides/tutorials/spring-security-and-angular-js

Ich kann den derzeit angemeldeten Benutzer nicht abmelden. Wenn ich eine POST-Anforderung für "/ logout" durchführe, wird vom Google Chrome-Debugger der Bildschirm "404 not found" (404 nicht gefunden) angezeigt:

WARUM ERHALTEN? Ich habe POST durchgeführt. Warum "/ login? Logout", nicht "/ logout"? Hier ist der Code, der aufgerufen wird, wenn der Benutzer auf die Schaltfläche zum Abmelden klickt:

$scope.logout = function() {
            $http.post('logout', {}).success(function() {
                $rootScope.authenticated = false;
                $location.path("/");
            }).error(function(data) {
                console.log("Logout failed")
                $rootScope.authenticated = false;
            });
        }

Spring code:

@SpringBootApplication
@RestController
public class UiApplication {

    @RequestMapping("/user")
    public Principal user(Principal user) {
        return user;
    }

    @RequestMapping("/resource")
    public Map<String, Object> home() {
        Map<String, Object> model = new HashMap<String, Object>();
        model.put("id", UUID.randomUUID().toString());
        model.put("content", "Hello World");
        return model;
    }

    public static void main(String[] args) {
        SpringApplication.run(UiApplication.class, args);
    }

    @Configuration
    @Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
    protected static class SecurityConfiguration extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.httpBasic().and().authorizeRequests()
                    .antMatchers("/index.html", "/home.html", "/login.html", "/").permitAll().anyRequest()
                    .authenticated().and().csrf()
                    .csrfTokenRepository(csrfTokenRepository()).and()
                    .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
        }

        private Filter csrfHeaderFilter() {
            return new OncePerRequestFilter() {
                @Override
                protected void doFilterInternal(HttpServletRequest request,
                        HttpServletResponse response, FilterChain filterChain)
                        throws ServletException, IOException {
                    CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
                            .getName());
                    if (csrf != null) {
                        Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                        String token = csrf.getToken();
                        if (cookie == null || token != null
                                && !token.equals(cookie.getValue())) {
                            cookie = new Cookie("XSRF-TOKEN", token);
                            cookie.setPath("/");
                            response.addCookie(cookie);
                        }
                    }
                    filterChain.doFilter(request, response);
                }
            };
        }

        private CsrfTokenRepository csrfTokenRepository() {
            HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
            repository.setHeaderName("X-XSRF-TOKEN");
            return repository;
        }
    }

}

Whole AngularJS-Code:

angular.module('hello', [ 'ngRoute' ]).config(function($routeProvider, $httpProvider) {

    $routeProvider
.when('/', {templateUrl : 'home.html', controller : 'home'  })
.when('/login', { templateUrl : 'login.html',   controller : 'navigation'   })
.otherwise('/');

    $httpProvider.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

}).controller('navigation',

        function($rootScope, $scope, $http, $location, $route) {

            $scope.tab = function(route) {
                return $route.current && route === $route.current.controller;
           };

            var authenticate = function(credentials, callback) {

                var headers = credentials ? {
                    authorization : "Basic "
                            + btoa(credentials.username + ":"
                                    + credentials.password)
                } : {};

                $http.get('user', {
                    headers : headers
                }).success(function(data) {
                    if (data.name) {
                        $rootScope.authenticated = true;
                    } else {
                        $rootScope.authenticated = false;
                    }
                    callback && callback($rootScope.authenticated);
                }).error(function() {
                    $rootScope.authenticated = false;
                    callback && callback(false);
                });

            }

            authenticate();
            $scope.credentials = {};            
            $scope.login = function() {
                authenticate($scope.credentials, function(authenticated) {
                    if (authenticated) {
                        console.log("Login succeeded")
                        $location.path("/");
                        $scope.error = false;
                        $rootScope.authenticated = true;
                    } else {
                        console.log("Login failed")
                        $location.path("/login");
                        $scope.error = true;
                        $rootScope.authenticated = false;
                    }
                })          
            };

            $scope.logout = function() {
                $http.post('logout', {}).success(function() {
                    $rootScope.authenticated = false;
                    $location.path("/");
                }).error(function(data) {
                    console.log("Logout failed")
                    $rootScope.authenticated = false;
                });         
            }

        }).controller('home', function($scope, $http) { 
           $http.get('/resource/').success(function(data) {         
               $scope.greeting = data; }) });

Ich bin neu im Frühling. Hier ist der gesamte Code aus dem Tutorial - funktioniert auch nicht:https: //github.com/dsyer/spring-security-angular/tree/master/singl
