Class MethodInterceptorDispatcher

java.lang.Object

com.bstek.dorado.util.proxy.MethodInterceptorDispatcher

All Implemented Interfaces:

javassist.util.proxy.MethodHandler, net.sf.cglib.proxy.Callback, net.sf.cglib.proxy.MethodInterceptor, org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor

Direct Known Subclasses:

BaseMethodInterceptorDispatcher, MethodInterceptorProxyDispatcher

public abstract class MethodInterceptorDispatcher
extends java.lang.Object
implements org.aopalliance.intercept.MethodInterceptor, net.sf.cglib.proxy.MethodInterceptor, javassist.util.proxy.MethodHandler

抽象的方法拦截器的分发者。

此类主要用于将一个基于net.sf.cglib.proxy.MethodInterceptor的方法拦截器中的调用 分发到一个或一组org.aopalliance.intercept.MethodInterceptor方法拦截器中。 使用此分发器即可以保证应用中定义的org.aopalliance.intercept.MethodInterceptor方法拦截器 可以同时应用于Cglib和Spring AOP，又可以实现对方法的迭代拦截（即同时启用多个拦截器拦截被代理对象的同一个方法）。
