Hello,
I'm trying to write a drools rule for the following situation:
I have a user profile object containing a list of Strings representing the roles this user has been granted.
I need a drools rule pattern that matches true if there is an intersection between the user's roles and a list of given roles.
In Java the rule logic would be:
ArrayList<String> okRoles = new ArrayList<String>();
okRoles.add("Internal");
okRoles.add("Admin");
Profile profile = // get profile from wherever...contains list of user's roles: {"User","Internal"}
if( okRoles.retainAll( profile.getRoles() ) == false ) {
// successful match
}
How can I do similar match logic in Drools? Here's where I'm at so far:
rule "Test1"
when
Profile(roles in ("Internal","Admin"))
then
System.out.println("Found role match!");
end
This rule actually runs w/o crashing, but fails to match...presumably because getRoles() returns a list of roles and the list is not in ("ROLE_BUYER").
Any hints how I can accomplish this?
Thanks!
Greg
