组成:

抽象角色:通过接口或抽象类声明真实角色实现的业务方法。

代理角色:实现抽象角色，是真实角色的代理，通过真实角色的业务逻辑方法来实现抽象方法，并可以附加自己的操作。

真实角色:实现抽象角色，定义真实角色所要实现的业务逻辑，供代理角色调用。

 

一个是真正的你要访问的对象(目标类)，一个是代理对象,真正对象与代理

对象实现同一个接口,先访问代理类再访问真正要访问的对象。

代理模式分为静态代理、动态代理。

静态代理是由程序员创建或工具生成代理类的源码，再编译代理类。所谓静态也就是在程序运行前就已经存在代理类的字节码文件，代理类和委托类的关系在运行前就确定了。

动态代理是在实现阶段不用关心代理类，而在运行阶段才指定哪一个对象。
