Explain proxy-target-class attribute of spring transactions.

The proxy-target-class attribute controls what type of transactional proxies are created for classes annotated with the @Transactional annotation. If proxy-target-class is set to true, class-based proxies are created. If proxy-target-class is false or if the attribute is omitted, standard JDK interface-based proxies are created.

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

You may use 'proxy-target-class="true"' on , or elements that will force the use of CGLIB proxies.
