Use of proxies in Spring AOP

by

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“):

 <aop:config proxy-target-class="true">
    <!-- other beans defined here... -->
 </aop:config>

When using AspectJ and its autopoxy support you can also force CGLIB proxies. This is where the <aop:aspectj-autoproxy> is used and also here the “proxy-target-class” must be set to true:

<aop:aspectj-autoproxy proxy-target-class="true"/>

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