I have a UserRoles (USER_ROLES_T) domain object which contains a Lookup child object which is an ID.

@Entity
@Table(name = "USER_ROLES_T")
public class UserRoles {
   //...
   private LookupT role;
}

@Entity
@Table(name = "LOOKUP_T") {
public class LookupT {
  //...
  private int id;
}

I need to run a Spring Data CRUD method (no annotations) whose name would find by role (LookupT) IN (List).

E.g.:

findUserRolesByRoleIdIn(List<Integer> roleIds);

findUserRolesByRoleIdIn(100,101);

But would this be correct? I'm not referencing a flat field called roleId. I need to find by role.id in (..). So what's the correct Spring Data CRUD signature to denote the child object's IN?
