Answer 1

Well you can use the springSecurityService to get some user information in a controller:

    class MyController {
      def springSecurityService

      def myAction() {
        def principal = springSecurityService.principal
        String username = principal.username
        ...
      }
     }

Or in a gsp

    <sec:loggedInUserInfo field="username" />

It is a pretty general question.

Answer 2

Define (in a controller, or service where you need user id):

SpringSecurityService springSecurityService

and try:

springSecurityService.currentUser.id //loads user from db, and returns its id

or:

springSecurityService.principal.id //if you need just id

Answer 3

add this @the top of your service or controller class

def securityService

this returns the cuureent user id.

securityService.currentUser.id
