Grails and Spring Security: How do I get the authenticated user from within a controller?

Question

I recently moved from the JSecurity plugin to Spring Security. How do I get the authenticated user from within my controllers?

Answer 1

I'm using 0.5.1 and the following works for me:

class EventController {
  def authenticateService

  def list = { 
     def user = authenticateService.principal() 
     def username = user?.getUsername()
     .....
     .....
  } 
}
