However you create AOP proxies, you can manipulate them using the org. spring frame work. aop. frame work. Advised interface.Any AOP proxy can be cast to this interface, whichever other interfaces it implements.This interface includes the following methods:
Advisor[] getAdvisors();The getAdvisors() method will return an Advisor for every advisor, interceptor or other advice type that has been added to the factory.If you added an Advisor, the returned advisor at this index will be the object that you added. If you added an interceptor or other advice type, Spring will have wrapped this in an advisor with a pointcut that always returns true.Thus if you added a Method Inter ceptor, the advisor returned for this index will be an Default Point cut Advisor returning your Method Interceptor and a pointcut that matches all classes and methods.
The addAdvisor() methods can be used to add any Advisor. Usually the advisor holding pointcut and advice will be the generic Default Point cutA dvisor, which can be used with any advice or pointcut (but not for introductions).
By default, it's possible to add or remove advisors or interceptors even once a proxy has been created. The only restriction is that it's impossible to add or remove an introduction advisor, as existing proxies from the factory will not show the interface change. (You can obtain a new proxy from the factory to avoid this problem.)
A simple example of casting an AOP proxy to the Advised interface and examining and manipulating its advice:
Advised advised = (Advised) myObject;Depending on how you created the proxy, you can usually set a frozen flag, in which case the Advised is Frozen() method will return true, and any attempts to modify advice through addition or removal will result in an AopConfigException. The ability to freeze the state of an advised object is useful in some cases, for example, to prevent calling code removing a security interceptor. It may also be used in Spring 1.1 to allow aggressive optimization if runtime advice modification is known not to be required.
