AspectJAdvisorFactory
Direct Known Subclasses:
ReflectiveAspectJAdvisorFactory
```
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.

```
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
    Parameters:
    clazz - the supposed annotation-style AspectJ class
    Returns:
    whether or not 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
    Parameters:
    aspectClass - the supposed AspectJ annotation-style class to validate
    Throws:
    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...).
