Answer 1

Well, you can use the springSecurityService function to get user information in the controller:

    class MyController {
      def springSecurityService

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

Or in gsp

    <sec:loggedInUserInfo field="username" />

This is a pretty general question.

Answer 2

Define (in the controller or service where you need the 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 @ to the top of your service or controller class

def securityService

this returns the cuureent user id.

securityService.currentUser.id
