public abstract class AbstractFallbackMethodSecurityMetadataSource extends AbstractMethodSecurityMetadataSource
MethodSecurityMetadataSourcethat supports both Spring AOP and AspectJ and performs attribute resolution from: 1. specific target method; 2. target class; 3. declaring method; 4. declaring class/interface. Use with
DelegatingMethodSecurityMetadataSourcefor caching support.
This class mimics the behaviour of Spring's AbstractFallbackTransactionAttributeSource class.
Note that this class cannot extract security metadata where that metadata is expressed by way of a target method/class (i.e. #1 and #2 above) AND the target method/class is encapsulated in another proxy object. Spring Security does not walk a proxy chain to locate the concrete/final target object. Consider making Spring Security your final advisor (so it advises the final target, as opposed to another proxy), move the metadata to declared methods or interfaces the proxy implements, or provide your own replacement MethodSecurityMetadataSource.

Note that the
Method.getDeclaringClass() may not equal the
targetClass. Both parameters are provided to assist subclasses which
may wish to provide advanced capabilities related to method metadata being
"registered" against a method even if the target class does not declare the method
(i.e. the subclass may only inherit the method).

Subclasses should only return metadata expressed at a class level. Subclasses
should NOT aggregate metadata for each method registered against a class, as the
abstract superclass will separate invoke
findAttributes(Method, Class) for
individual methods as appropriate.
