Note: We can't simply component-scan the PermissionEvaluatorManager because we have numerous of PermissionEvaluators on the classpath. Heres an EmployeePermissionEvaluator: With all that in place, we just need to configure the framework, and we can start securing APIs with Method Security and using other features of the authorization framework.
