Java怎么实现多层动态代理？

java复制代码// 定义需要被代理的接口
public interface MyInterface {
    void myMethod();
}

// 实现 InvocationHandler 接口
public class MyInvocationHandler implements InvocationHandler {

    private Object target;

    public MyInvocationHandler(Object target) {
        this.target = target;
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
        // 处理逻辑
        System.out.println("before method");
        Object result = method.invoke(target, args);
        System.out.println("after method");

        return result;
    }
}

// 测试代码
public class Main {

    public static void main(String[] args) {
        MyInterface targetObject = new MyInterfaceImpl();
        MyInvocationHandler handler1 = new MyInvocationHandler(targetObject);

        MyInterface proxy1 = (MyInterface) Proxy.newProxyInstance(
            targetObject.getClass().getClassLoader(),
            targetObject.getClass().getInterfaces(),
            handler1
        );

        MyInvocationHandler handler2 = new MyInvocationHandler(proxy1);

        MyInterface proxy2 = (MyInterface) Proxy.newProxyInstance(
            proxy1.getClass().getClassLoader(),
            proxy1.getClass().getInterfaces(),
            handler2
        );

        proxy2.myMethod();
    }
}
