接口 AspectJAdvisorFactory

方法详细资料

• isAspect

  boolean isAspect​(Class<?> clazz)

  Determine whether or not the given class is an aspect, as reported by AspectJ's AjTypeSystem.

  Will simply return false if the supposed aspect is invalid (such as an extension of a concrete aspect class). Will return true for some aspects that Spring AOP cannot process, such as those with unsupported instantiation models. Use the validate(java.lang.Class<?>) method to handle these cases if necessary.

  参数:

  clazz - the supposed annotation-style AspectJ class

  返回:

  whether or not this class is recognized by AspectJ as an aspect class

• validate

  void validate​(Class<?> aspectClass)
         throws AopConfigException

  Is the given class a valid AspectJ aspect class?

  参数:

  aspectClass - the supposed AspectJ annotation-style class to validate

  抛出:

  AopConfigException - if the class is an invalid aspect (which can never be legal)

  NotAnAtAspectException - if the class is not an aspect at all (which may or may not be legal, depending on the context)

• getAdvisors

  List<Advisor> getAdvisors​(MetadataAwareAspectInstanceFactory aspectInstanceFactory)

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

  参数:

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

  返回:

  a list of advisors for this class

• getAdvisor

  Advisor getAdvisor​(Method candidateAdviceMethod,
                     MetadataAwareAspectInstanceFactory aspectInstanceFactory,
                     int declarationOrder,
                     String aspectName)

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

  参数:

  candidateAdviceMethod - the candidate advice method

  aspectInstanceFactory - the aspect instance factory

  declarationOrder - the declaration order within the aspect

  aspectName - the name of the aspect

  返回:

  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

  Advice getAdvice​(Method candidateAdviceMethod,
                   AspectJExpressionPointcut expressionPointcut,
                   MetadataAwareAspectInstanceFactory aspectInstanceFactory,
                   int declarationOrder,
                   String aspectName)

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

  参数:

  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

  返回:

  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
