Class JdkDynamicAopProxy

final class JdkDynamicAopProxy

implements AopProxy, InvocationHandler

InvocationHandler implementation for the Spring AOP framework, based on J2SE 1.3+ dynamic proxies.

Creates a J2SE proxy, implementing the interfaces exposed by the proxy. Dynamic proxies cannot be used to proxy methods defined in classes, rather than interface.

Objects of this type should be obtained through proxy factories, configured by an AdvisedSupport class. This class is internal to the Spring framework and need not be used directly by client code.

Proxies created using this class will be threadsafe if the underlying (target) class is threadsafe.

public Object invoke(Object proxy, Method method, Object[] args)
