Class Overview

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.

Summary

Nested Classes
class AbstractAspectJAdvisorFactory.AspectJAnnotation<A extends Annotation> Class modelling an AspectJ annotation, exposing its type enumeration and pointcut String. 
enum AbstractAspectJAdvisorFactory.AspectJAnnotationType  
Fields
protected static final ParameterNameDiscoverer ASPECTJ_ANNOTATION_PARAMETER_NAME_DISCOVERER
protected final Log logger Logger available to subclasses
protected final ParameterNameDiscoverer parameterNameDiscoverer
Protected Constructors
AbstractAspectJAdvisorFactory()
Public Methods
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.
void validate(Class<?> aspectClass)
Is the given class a valid AspectJ aspect class?
Protected Methods
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.
static AspectJAnnotation findAspectJAnnotationOnMethod(Method method)
Find and return the first AspectJ annotation on the given method (there should only be one anyway...)

Public Methods

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.

Parameters
clazz the supposed annotation-style AspectJ class
Returns
  • whether or not this class is recognized by AspectJ as an aspect class

public void validate (Class<?> aspectClass)

Is the given class a valid AspectJ aspect class?

Parameters
aspectClass the supposed AspectJ annotation-style class to validate
Throws
AopConfigException

Protected Methods

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. We use this (if non-empty) to build the formal parameters for the pointcut.

protected static AspectJAnnotation findAspectJAnnotationOnMethod (Method method)

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