Method Details

getAdvisors

public List<Advisor> getAdvisors(MetadataAwareAspectInstanceFactory aspectInstanceFactory)

Description copied from interface: AspectJAdvisorFactory

Build Spring AOP Advisors for all annotated At-AspectJ methods on the specified aspect instance.

Specified by:

getAdvisors in interface AspectJAdvisorFactory

Parameters:

aspectInstanceFactory - the aspect instance factory (not the aspect instance itself in order to avoid eager instantiation)

Returns:

a list of advisors for this class

getAdvisor

public @Nullable Advisor getAdvisor(Method candidateAdviceMethod,
 MetadataAwareAspectInstanceFactory aspectInstanceFactory,
 int declarationOrderInAspect,
 String aspectName)

Description copied from interface: AspectJAdvisorFactory

Build a Spring AOP Advisor for the given AspectJ advice method.

Specified by:

getAdvisor in interface AspectJAdvisorFactory

Parameters:

candidateAdviceMethod - the candidate advice method

aspectInstanceFactory - the aspect instance factory

declarationOrderInAspect - the declaration order within the aspect

aspectName - the name of the aspect

Returns:

null if the method is not an AspectJ advice method or if it is a pointcut that will be used by other advice but will not create a Spring advice in its own right

getAdvice

public @Nullable Advice getAdvice(Method candidateAdviceMethod,
 AspectJExpressionPointcut expressionPointcut,
 MetadataAwareAspectInstanceFactory aspectInstanceFactory,
 int declarationOrder,
 String aspectName)

Description copied from interface: AspectJAdvisorFactory

Build a Spring AOP Advice for the given AspectJ advice method.

Specified by:

getAdvice in interface AspectJAdvisorFactory

Parameters:

candidateAdviceMethod - the candidate advice method

expressionPointcut - the AspectJ expression pointcut

aspectInstanceFactory - the aspect instance factory

declarationOrder - the declaration order within the aspect

aspectName - the name of the aspect

Returns:

null if the method is not an AspectJ advice method or if it is a pointcut that will be used by other advice but will not create a Spring advice in its own right
