Deprecated.
please use AclPermissionEvaluator instead. Spring Method Security annotations may also prove useful, for example @PreAuthorize("hasPermission(#id, ObjectsReturnType.class, read)")

Given a domain object instance passed as a method argument, ensures the principal has appropriate permission as indicated by the AclService.

The AclService is used to retrieve the access control list (ACL) permissions associated with a domain object instance for the current Authentication object.

The voter will vote if any ConfigAttribute.getAttribute() matches the processConfigAttribute. The provider will then locate the first method argument of type AbstractAclVoter.processDomainObjectClass. Assuming that method argument is non-null, the provider will then lookup the ACLs from the AclManager and ensure the principal is Acl.isGranted(List, List, boolean) when presenting the requirePermission array to that method.

If the method argument is null, the voter will abstain from voting. If the method argument could not be found, an AuthorizationServiceException will be thrown.

In practical terms users will typically setup a number of AclEntryVoters. Each will have a different processDomainObjectClass, processConfigAttribute and requirePermission combination. For example, a small application might employ the following instances of AclEntryVoter:

  • Process domain object class BankAccount, configuration attribute VOTE_ACL_BANK_ACCONT_READ, require permission BasePermission.READ
  • Process domain object class BankAccount, configuration attribute VOTE_ACL_BANK_ACCOUNT_WRITE, require permission list BasePermission.WRITE and BasePermission.CREATE (allowing the principal to have either of these two permissions)
  • Process domain object class Customer, configuration attribute VOTE_ACL_CUSTOMER_READ, require permission BasePermission.READ
  • Process domain object class Customer, configuration attribute VOTE_ACL_CUSTOMER_WRITE, require permission list BasePermission.WRITE and BasePermission.CREATE
Alternatively, you could have used a common superclass or interface for the AbstractAclVoter.processDomainObjectClass if both BankAccount and Customer had common parents.

If the principal does not have sufficient permissions, the voter will vote to deny access.

All comparisons and prefixes are case sensitive.

      protected String getInternalMethod()
      Deprecated.
      Optionally specifies a method of the domain object that will be used to obtain a contained domain object. That contained domain object will be used for the ACL evaluation. This is useful if a domain object contains a parent that an ACL evaluation should be targeted for, instead of the child domain object (which perhaps is being created and as such does not yet have any ACL permissions)
      Returns:
      null to use the domain object, or the name of a method (that requires no arguments) that should be invoked to obtain an Object which will be the domain object used for ACL evaluation
