I want to use @PreAuthorize annotation on service methods with Spring Security. One of requirements is to use role-hierarchy. But by default it is not enabled.

I found that in SecurityExpressionRoot class ("the base class for expression root objects") there is a property roleHierarchy. The class actually does use this property for methods like hasRole() and hasAnyRole().

I suppose that if I supply it with my own RoleHierarchy bean I will be able to use @PreAuthorize annotations with hierarchical roles.

How can I inject my hierarchy bean into SecurityExpressionRoot?
