How to get current user role with spring security plugin?

Question

I am using the spring-security-core plugin in my grails app. I need to know the current user\'s role in a controller action. How can I retrieve that?

Answer 1

From a controller you can use two methods the plugin adds to the metaclass, getPrincipal and isLoggedIn:

def myAction = {
   if (loggedIn) {
      // will be a List of String
      def roleNames = principal.authorities*.authority
   }
}

If the action is secured you can skip the loggedIn/isLoggedIn() check.
