What are the types of Advice?
Types of advice:
Before advice: Advice that executes before a join point, but which
does not have the ability to prevent execution flow proceeding to the join point
(unless it throws an exception).
After returning advice: Advice to be executed after a join point
completes normally: for example, if a method returns without throwing an
exception.
After throwing advice: Advice to be executed if a method exits by
throwing an exception.
After (finally) advice: Advice to be executed regardless of the
means by which a join point exits (normal or exceptional return).
Around advice: Advice that surrounds a join point such as a method
invocation. This is the most powerful kind of advice. Around advice can perform
custom behavior before and after the method invocation. It is also responsible
for choosing whether to proceed to the join point or to shortcut the advised
method execution by returning its own return value or throwing an exception.
