Spring Security - Third Edition

Optimizing AclPermission Cache

The DefaultMethodSecurityExpressionHandler object then delegates to a PermissionEvalulator instance. For the purposes of this chapter, we are using ACLs so that the bean we will use AclPermissionEvaluator, which will read the ACLs that we define in our database. You can view the provided configuration for permissionEvaluator, as follows:

src/main/java/com/packtpub/springsecurity/configuration/AclConfig.java@Beanpublic AclPermissionEvaluator permissionEvaluator(){   return new AclPermissionEvaluator(aclService());}
