Spring AOP
nAspects – unit of modularity for crosscutting concerns. A modularization of a concern that cuts across multiple
objects. Invocations that should
be handled similarly.
nAn aspect is the combination of advice and pointcuts into functional units in much the same way that OOP uses
classes to package fields
and methods into cohesive units.
nFor example, you might have a logging aspect
that contains advice and
pointcuts for applying logging code to all setter and getter methods on objects.
nWeaving – Process of actually inserting aspects/advice (crosscutting concerns) into the application code (core
concerns) at the
appropriate point
