静态代理

public class RealSubject implements Subject{ @Override public void doSomething() { System.out.println(\"执行业务逻辑\"); }}

public class StaticProxyTest { public static void main(String[] args) { RealSubject realSubject = new RealSubject(); StaticProxy staticProxy = new StaticProxy(realSubject); staticProxy.doSomething(); }}

代理类

增加业务执行后逻辑

静态代理

真实对象 RealSubject

将真实对象传入代理对象中

代理对象实现 Subject 接口

调用代理对象中方法

虚拟对象 Subject

目标方法

增加业务执行前逻辑

public interface Subject { void doSomething();}

public class StaticProxy implements Subject{ private RealSubject realSubject; StaticProxy(RealSubject realSubject) { this.realSubject = realSubject; } @Override public void doSomething() { System.out.println(\"添加业务前处理...\"); realSubject.doSomething(); System.out.println(\"添加业务后处理...\"); }}
