About Spring Dynamic agents

By default, Spring generates agents according to the following rules:

When the class has an implementation interface, Spring generates the Jdkdynamicaopproxy proxy

When the class does not implement an interface, Spring generates the Cglibaopproxy proxy

If you want to force spring to generate Cglibaopproxy proxies, you can <aop:config proxy-target-class= "true" > </aop:config>

When you need to use the Cglib Proxy and @aspectj automatic proxy support, set <aop:aspectj-autoproxy> the properties as follows proxy-target-class : <aop:aspectj-autoproxy proxy-target-class= "true" />

return target;
}
