Class AbstractAspectJAdvisorFactory

All Implemented Interfaces:
Direct Known Subclasses:

public abstract class AbstractAspectJAdvisorFactory extends Object implements AspectJAdvisorFactory
Abstract base class for factories that can create Spring AOP Advisors given AspectJ classes from classes honoring the AspectJ 5 annotation syntax.

This class handles annotation parsing and validation functionality. It does not actually generate Spring AOP Advisors, which is deferred to subclasses.

  • Method Details

    • isAspect

      public boolean isAspect(Class<?> clazz)
      We consider something to be an AspectJ aspect suitable for use by the Spring AOP system if it has the @Aspect annotation, and was not compiled by ajc. The reason for this latter test is that aspects written in the code-style (AspectJ language) also have the annotation present when compiled by ajc with the -1.5 flag, yet they cannot be consumed by Spring AOP.
      Specified by:
      isAspect in interface AspectJAdvisorFactory
      clazz - the supposed annotation-style AspectJ class
      whether this class is recognized by AspectJ as an aspect class
    • validate

      public void validate(Class<?> aspectClass) throws AopConfigException
      Description copied from interface: AspectJAdvisorFactory
      Is the given class a valid AspectJ aspect class?
      Specified by:
      validate in interface AspectJAdvisorFactory
      aspectClass - the supposed AspectJ annotation-style class to validate
      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)
    • findAspectJAnnotationOnMethod

      @Nullable protected static AbstractAspectJAdvisorFactory.AspectJAnnotation<?> findAspectJAnnotationOnMethod(Method method)
      Find and return the first AspectJ annotation on the given method (there should only be one anyway...).
