Spring AOP 方式二 ProxyFactory

例子

public interface IHello {

    public void say();
    
}


public class HelloImpl implements IHello {

    public void say() {
        System.out.println("Hello World");
    }
}


public class HelloInterceptor implements MethodInterceptor {

    public Object invoke(MethodInvocation methodinvocation) throws Throwable {

        System.out.println("start");

        Object ob = methodinvocation.proceed();

        System.out.println("end");

        return ob;
    }

}


public class HelloTest {

    public static void main(String[] args) {

        ProxyFactory factory = new ProxyFactory(new HelloImpl());
        factory.addAdvice(new HelloInterceptor());
        IHello hello = (IHello) factory.getProxy();

        hello.say();

    }
}

结果：
start
Hello World
end

实现原理和Spring AOP方式一的原理一致。
