Class DefaultAopProxyFactory

java.lang.Object

org.springframework.aop.framework.DefaultAopProxyFactory

All Implemented Interfaces:

java.io.Serializable, AopProxyFactory

public class DefaultAopProxyFactory
extends java.lang.Object
implements AopProxyFactory, java.io.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.
