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?

If the user is logged in, we use wp_get_current_user to return the WP_User object. This provides us with a stack of information about the data and we can access their user role(s) via $user->roles . Note that I've cast this to an array for safety. At this stage, you can choose how to return the roles.
The first way to check for user roles in Java is to use the @PreAuthorize annotation provided by Spring Security. This annotation can be applied to a class or method, and it accepts a single string value that represents a SpEL expression. Before we can use this annotation, we must first enable global method security.
You can inject springSecurityService into your controller:
def springSecurityService
and then in your action, call:
def roles = springSecurityService.getPrincipal().getAuthorities()
See the docs here.
