Cglib Dynamic Agent

The dynamic agent of JDK is slow, can use the agent of Cglib, the speed is relatively fast:

Package cn.demo02;

import Java.lang.reflect.Method;

Import Java.util.zip.CheckedInputStream;

import org.springframework.beans.BeansException;

import org.springframework.beans.factory.config.BeanPostProcessor;

import org.springframework.cglib.proxy.Enhancer;

import org.springframework.cglib.proxy.MethodInterceptor;

import org.springframework.cglib.proxy.MethodProxy;

Public class Postbean implements beanpostprocessor {

@Override

Public Object Postprocessbeforeinitialization (Object bean, String beanname) throws beansexception {

return Bean;

}

@Override

Public Object Postprocessafterinitialization (Object bean, String beanname) throws beansexception {

if (Bean instanceof Child) {

CG(Code generation)Lib dynamic agent for Beans

Object Proxybean = enhancer. Create (Bean.getclass (), new methodinterceptor () {

@Override

Public Object Intercept (Object Proxybean, method, object[] args, Methodproxy methodproxy)

throws Throwable {

if (Method.getname (). Equals ("Say")) {

System. err. println ("Say is beging ...");

Object obj = Methodproxy.invokesuper (Proxybean, args);

System. err. println ("Say Is over ...");

return obj;

} Else {

Direct release

return method.invoke (bean, args); }

}

});

return Proxybean;

}

return Bean;

}

}
