publicList getInterceptorsAndDynamicInterceptionAdvice(Advised config, Methodmethod, Class targetClass) {  

// This is somewhat tricky... we have to process introductions first,  

// but we need to preserve order in the ultimate list.  

List interceptorList = new ArrayList(config.getAdvisors().length);  

//查看是否包含IntroductionAdvisor  

boolean hasIntroductions = hasMatchingIntroductions(config,targetClass); 

//这里实际上注册一系列AdvisorAdapter,用于将Advisor转化成MethodInterceptor  

AdvisorAdapterRegistry registry = GlobalAdvisorAdapterRegistry.getInstance();  

Advisor[] advisors = config.getAdvisors();  
        for (int i = 0; i

// Add it conditionally.  

PointcutAdvisor pointcutAdvisor= (PointcutAdvisor) advisor;  

if(config.isPreFiltered() ||pointcutAdvisor.getPointcut().getClassFilter().matches(targetClass)) {  

//TODO: 这个地方这两个方法的位置可以互换下  

//将Advisor转化成Interceptor
