org.springframework.aop.framework
public class: DefaultAopProxyFactory [javadoc | source]

java.lang.Object
   org.springframework.aop.framework.DefaultAopProxyFactory

All Implemented Interfaces:
AopProxyFactory, Serializable

Default AopProxyFactory implementation, creating either a CGLIB proxy or a JDK dynamic proxy.

Creates a CGLIB proxy if one the following is true for a given AdvisedSupport instance:

the "optimize" flag is set
the "proxyTargetClass" flag is set
no proxy interfaces have been specified

Note that the CGLIB library classes have to be present on the class path if an actual CGLIB proxy needs to be created.

In general, specify "proxyTargetClass" to enforce a CGLIB proxy, or specify one or more interfaces to use a JDK dynamic proxy.
