public interface Advisor
Base interface holding AOP advice (action to take at a joinpoint) and a filter determining the applicability of the advice (such as a pointcut). This interface is not for use by Spring users, but to allow for commonality in support for different types of advice.Spring AOP is based around around advice delivered via method interception, compliant with the AOP Alliance interception API. The Advisor interface allows support for different types of advice, such as before and after advice, which need not be implemented using interception.

isPerInstance
boolean isPerInstance()
Return whether this advice is associated with a particular instance (for example, creating a mixin) or shared with all instances of the advised class obtained from the same Spring bean factory.Note that this method is not currently used by the framework. Typical Advisor implementations always return
true. Use singleton/prototype bean definitions or appropriate programmatic proxy creation to ensure that Advisors have the correct lifecycle model.- 返回:
- whether this advice is associated with a particular target instance
