用户通过身份验证/记录时，Symfony 2.5.7自动重定向

Question

Good evening, How is it possible to "auto-redirect" a user to the /account area, when he has the role e.g. ROLE_USER, so when he is authenticated / has logged in ? (Not anonymously)

I want to prevent the user to get access to the "standard" fos userbundle pages :

The "login form", "registration form" and "password reset" form,

when he is logged in That doesn't make sense for me if the user is already logged in and can log in a second time or reset his password or register again..

What is the best approach to handle that?

Regards

Expanding on my answer in the comments.

The best approach that I can think off would be to listen for the kernel.controller event. Then in this event check whether the controller is in your list of blacklisted controller to decide whether or not to forward your user by way of exception.

This will listen for the kernel.controller event. It will then check whether the controller is one of the 3 FOSUserBundle controller that you want to miss if the user is logged in. If the controller is one of those then an exception is thrown which is then caught by the kernel.exception event. If the exception is the one specified then you forward the user to the route that you state in the redirect response.
