Class AbstractAspectJAdvisorFactory
java.lang.Object
org.springframework.aop.aspectj.annotation.AbstractAspectJAdvisorFactory
- All Implemented Interfaces:
AspectJAdvisorFactory
- Direct Known Subclasses:
ReflectiveAspectJAdvisorFactory
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.

isAspect
Description copied from interface:AspectJAdvisorFactory
Determine whether the given class is an aspect, as reported by AspectJ'sAjTypeSystem
.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 theAspectJAdvisorFactory.validate(java.lang.Class<?>)
method to handle these cases if necessary.- Specified by:
isAspect
in interfaceAspectJAdvisorFactory
- Parameters:
clazz
- the supposed annotation-style AspectJ class- Returns:
- whether this class is recognized by AspectJ as an aspect class
-
validate
Description copied from interface:AspectJAdvisorFactory
Is the given class a valid AspectJ aspect class?- Specified by:
validate
in interfaceAspectJAdvisorFactory
- 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...).
