How does spring annotation @aspect for spring source analysis work?

1. @Aspect

1.1 Registration

Org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator

The following are the inheritance relationships:

1.2 Concrete Implementation class is: Abstractautoproxycreator's Postprocessafterinitialization () method

Defaultaopproxyfactory#createaopproxy () method

@Override PublicAopproxy createaopproxy (advisedsupport config)throwsaopconfigexception {if(Config.isoptimize () | | config.isproxytargetclass () | |hasnousersuppliedproxyinterfaces (config)) {Class<?> Targetclass =Config.gettargetclass (); if(Targetclass = =NULL) {                Throw NewAopconfigexception ("Targetsource cannot determine target class:" + "either an interface or a targe T is required for proxy creation. "); }            if(Targetclass.isinterface ()) {return new jdkdynamicaopproxy (config); }            return new objenesiscglibaopproxy (config); }        Else {            return Newjdkdynamicaopproxy (config); }    }

The default use of the JDK comes with a proxy, there is a cglib way.
