Secure all urls in Symfony2

I am using Symfony 2.6.6. And my structure folder

ExampleBundle
   Controller
       LoginController.php
       Other1Controller.php
       Other2Controller.php
       ...

      

        
        
        
      

    

LoginController

has loginAction()

and will loginCheckAction()


loginAction()

display a registration form and loginCheckAction()

to verify this.

I see several tutorials for creating LoginController.php

. After the user logs in using validation, I set:

$session->set('login', $login);

      

        
        
        
      

    

My goal: All users must be logged in before accessing the entire page of my web application.

But my site has a lot of controllers and actions (pages).

My idea : check 'login' session exists in all Action of all Controller and redirects the login action if it doesn't exist.

But I think this is too tame. What's the best way to do this with Symfony?

Update 1:
After this I am trying to add some code to my file security.yml

. It is redirected to the login page if the user is not registered, but it is always redirected to the login page. I want the user to be logged in (has a "login" section), he can access other pages. how to do it thanks

# .../security.html
security:
    firewalls:
       ex_login:
            pattern:  ^/ex/login$
            anonymous: ~
            security: false
        secured_area:
            pattern:    ^/ex
            form_login:
                check_path: /ex/logincheck
                login_path: /ex/login
            logout:
                path: /ex/logout
                target: /ex

      

        
        
        
      

    

update 2
here is mineLogin Controller

       loginAction() {
           $session = $this->getRequest()->getSession();
           if ($session->has('login')) {
               //redirect to home/index
           }else {
               //render login form
           }
       }
       logincheckAction(Request $request) {
           if($request->getMethod()=='POST') {
                // check user input (username && password) in database
                if (ok){
                     $session->set('login', 'true');
                     //redirect to home/index
                }
                else {
                     //redirect to login/index
                }
           }else {
                //redirect to login/index
           }
       }
       logoutAction() {
           //remove login session
           // redirect to login/index
       }

      

        
        
        
      

    

Here is my Other1Controller.php

indexAction(){
   echo 'page1';
}

      

        
        
        
      

    

It is always redirected to the login page. After I fill in my field and ask to login, is it still redirected to the login page? how can i fix this thanks.
