springboot和angularjs的注销问题

@Controller
public class LogoutController {

    @RequestMapping("/logout")
    public String logout(HttpServletRequest request, HttpServletResponse response) {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        if (auth != null) {
            new SecurityContextLogoutHandler().logout(request, response, auth);
        }
        return "redirect:/login?logout";
    }
}

app.factory('LogoutService', ['$http', function($http) {
    var logout = function() {
        return $http.post('/logout');
    };

    return {
        logout: logout
    };
}]);

app.controller('LogoutController', ['$scope', 'LogoutService', function($scope, LogoutService) {
    $scope.logout = function() {
        LogoutService.logout().then(function(response) {
            // 处理注销成功后的逻辑
        }, function(error) {
            // 处理注销失败后的逻辑
        });
    };
}]);
