Spring AOP uses either JDK dynamic proxies or CGLIB to create the proxies for your target objects.

According to Spring documentation, in case your target implements at least one interface, a JDK dynamic proxy will be used. However if your target object does not implement any interfaces then a CGLIB proxy will be created.

This is how you can force creation of the CGLIB proxies (set proxy-target-class="true"):

When using AspectJ and its autopoxy support you can also force CGLIB proxies. This is where the is used and also here the "proxy-target-class" must be set to true:

Please refer to Proxying mechanisms section of Aspect Oriented Programming with Spring documentation for more details.
