public interface PermissionResolver
PermisisonResolver resolves a String value and converts it into a
Permission instance.
The default WildcardPermissionResolver should be
suitable for most purposes, which constructs WildcardPermission objects.
However, any resolver may be configured if an application wishes to use different
Permission implementations.
A PermissionResolver is used by many Shiro components such as annotations, property file
configuration, URL configuration, etc. It is useful whenever a String representation of a permission is specified
and that String needs to be converted to a Permission instance before executing a security check.
Shiro chooses to support Wildcardpermissions by default in almost all components and
we do that in the form of the WildcardPermissionResolver. One of the nice
things about WildcardPermissions being supported by default is that it makes it very easy to
store complex permissions in the database - and also makes it very easy to represent permissions in JSP files,
annotations, etc., where a simple string representation is useful.
Although this happens to be the Shiro default, you are of course free to provide custom
String-to-Permission conversion by providing Shiro components any instance of this interface.| Modifier and Type | Method and Description |
