Grails: User evaluator for Commentable with Spring Security plugin

Question

I am trying to use the commentable plugin with Spring Security.

I can't manage to write the right

grails.commentable.poster.evaluator

I tried {User.get(springSecurityService.principal.id)}, but from the CommentController, both User and springSecurity seems unaccessible.

What should I do?

Answer 1

For springSecurityService.principal.id since there's no dependency injection field for springSecurityService it can't work, so you need to call what springSecurityService.principal.id calls - org.springframework.security.core.context.SecurityContextHolder.context.authentication.principal.id

To fix the problem with User, you'll need the full class name with package. So combined, this should be

{com.yourcompany.yourapp.User.get(org.springframework.security.core.context.SecurityContextHolder.context.authentication.principal.id)}
