Class AbstractAspectJAdvisorFactory

java.lang.Object
  org.springframework.aop.aspectj.annotation.AbstractAspectJAdvisorFactory

All Implemented Interfaces:: AspectJAdvisorFactory

Direct Known Subclasses:: ReflectiveAspectJAdvisorFactory

public abstract class AbstractAspectJAdvisorFactory
extends Object
implements AspectJAdvisorFactory
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.

Since:: 2.0
Author:: Rod Johnson, Adrian Colyer, Juergen Hoeller

Method Summary

protected AspectJExpressionPointcut createPointcutExpression(Method annotatedMethod, Class declarationScope, String[] pointcutParameterNames)
          The pointcut and advice annotations both have an "argNames" member which contains a comma-separated list of the argument names.

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

boolean isAspect(Class<?> clazz)
          Determine whether or not the given class is an aspect, as reported by AspectJ's AjTypeSystem.

void validate(Class<?> aspectClass)
          Is the given class a valid AspectJ aspect class?

Method Detail

findAspectJAnnotationOnMethod

protected static AbstractAspectJAdvisorFactory.AspectJAnnotation findAspectJAnnotationOnMethod(Method aMethod)

Find and return the first AspectJ annotation on the given method (there should only be one anyway...)

isAspect

public boolean isAspect(Class<?> clazz)

Description copied from interface: AspectJAdvisorFactory

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 AspectJAdvisorFactory.validate(java.lang.Class) method to handle these cases if necessary.

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
