public AspectJInvocationContextExposingAdvisorAutoProxyCreator()

Method Detail

extendCandidateAdvisors

protected void extendCandidateAdvisors(List 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:

extendCandidateAdvisors in class AbstractAdvisorAutoProxyCreator

Parameters:

candidateAdvisors - Advisors that have already been identified as applying to a given bean

sortAdvisors

protected List sortAdvisors(List advisors)

Keep the special ExposeInvocationInterceptor at position 0 if present. Sort the rest by order. 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:

• if either of the pair is after advice, then the advice declared last gets highest precedence (runs last)
• otherwise the advice declared first gets highest precedence (runs first)

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
