RoleHierarchy

@groovy.transform.CompileStatic
class MutableRoleHierarchy
extends java.lang.Object
implements RoleHierarchy

A mutable RoleHierarchy that allows the hierarchy definition to be replaced at runtime, working around the immutability of Spring Security's RoleHierarchyImpl.

Spring Security 6 made RoleHierarchyImpl effectively immutable by removing public mutators in favour of RoleHierarchyImpl.fromHierarchy(...). This class wraps a delegate that is rebuilt every time the hierarchy string is assigned, so callers (such as the plugin's roleHierarchy bean and any application code that reads grails.plugin.springsecurity.roleHierarchy at runtime) keep their original setter-based API.

The hierarchy property uses the standard Spring Security syntax, with one assignment per line, e.g.:

 ROLE_ADMIN > ROLE_USER
 ROLE_USER > ROLE_GUEST
 

Setting the property to null or an empty string clears the hierarchy.
