public abstract class AbstractAdvisorAutoProxyCreator
Generic auto proxy creator that builds AOP proxies for specific beans based on detected Advisors for each bean.
Subclasses must implement the abstract findCandidateAdvisors()
method to return a list of Advisors applying to any object. Subclasses can
also override the inherited AbstractAutoProxyCreator.shouldSkip(java.lang.Class, java.lang.String)
method to exclude certain
objects from auto-proxying.
Advisors or advices requiring ordering should implement the
Ordered
interface. This class sorts
Advisors by Ordered order value. Advisors that don't implement the
Ordered interface will be considered as unordered; they will appear
at the end of the advisor chain in undefined order.
