Constructor Detail

AspectJAwareAdvisorAutoProxyCreator

public AspectJAwareAdvisorAutoProxyCreator()
Method Detail

sortAdvisors

protected java.util.List<Advisor> sortAdvisors(java.util.List<Advisor> advisors)
Sort the rest by AspectJ precedence. If two pieces of advice have come from the same aspect they will have the same order. Advice from the same aspect is then further ordered according to the following rules:

Important: Advisors are sorted in precedence order, from highest precedence to lowest. "On the way in" to a join point, the highest precedence advisor should run first. "On the way out" of a join point, the highest precedence advisor should run last.

Overrides:
sortAdvisors in class AbstractAdvisorAutoProxyCreator
Parameters:
advisors - the source List of Advisors
Returns:
the sorted List of Advisors

Ordered, OrderComparator

extendAdvisors

protected void extendAdvisors(java.util.List<Advisor> candidateAdvisors)
Adds an ExposeInvocationInterceptor to the beginning of the advice chain. These additional advices are needed when using AspectJ expression pointcuts and when using AspectJ-style advice.

Overrides:
extendAdvisors in class AbstractAdvisorAutoProxyCreator
Parameters:
candidateAdvisors - Advisors that have already been identified as applying to a given bean

shouldSkip

protected boolean shouldSkip(java.lang.Class beanClass,
                             java.lang.String beanName)
Description copied from class: AbstractAutoProxyCreator
Subclasses should override this method to return true if the given bean should not be considered for auto-proxying by this post-processor.

Sometimes we need to be able to avoid this happening if it will lead to a circular reference. This implementation returns false.

Overrides:
shouldSkip in class AbstractAutoProxyCreator
Parameters:
beanClass - the class of the bean
beanName - the name of the bean
Returns:
whether to skip the given bean
