title: How can I get the current user roles from Spring security 3.1
body: <p>I have loaded the roles from the database for the current user. And I can access the user role with spring security expression in JSP, and can hide the options and URLs which are not authorized with hasRole. Now I wanted to have it in the servlet and display it in the logs (or store in the user object session). How can we achieve it?</p>
