Using reflection to implement dynamic proxy

Proxy mode: Proxy mode definition: Provides a proxy for other objects to control access to this object. In some cases, an object may not fit or directly refer to another object, and the proxy object can act as a mediator between the client and the target object.

The analysis was designed to three objects:

One: Abstract class interface

Second: By proxy class (specific implementation of the abstract interface Class)

Three: proxy class: A class that actually invokes methods and properties of the proxy class,

Dynamic proxies invoke proxy class methods and properties by creating Run-time class objects based on class classes loaded by objects in memory. The specific code example is below.

void Fly (); }//represented Class class Superman implements Human {public void info () {System.out.println ("I am Superman.") I'm afraid of WHO.

	public void Fly () {System.out.println ("I Believe I can fly!"); The class Myinvocationhandler implements Invocationhandler {object obj;//the declared public void setobject of the proxy class object (object ob
