Get AOP proxy from the object itself

Question

Is possible to get the proxy of a given object in Spring? I need to call a function of a subclass. But, obviously, when I do a direct call, the aspects aren't applied. Here's an example:

public class Parent {

    public doSomething() {
        Parent proxyOfMe = Spring.getProxyOfMe(this); // (please)
        Method method = this.class.getMethod("sayHello");
        method.invoke(proxyOfMe);
    }
}

public class Child extends Parent {

    @Secured("president")
    public void sayHello() {
        System.out.println("Hello Mr. President");
    }
}

I've found a way of achieving this. It works, but I think is not very elegant:

public class Parent implements BeanNameAware {

    @Autowired private ApplicationContext applicationContext;
    private String beanName; // Getter

    public doSomething() {
        Parent proxyOfMe = applicationContext.getBean(beanName, Parent.class);
        Method method = this.class.getMethod("sayHello");
        method.invoke(proxyOfMe);
    }
}

This hack is extremely awkward, please consider refactoring your code or using AspectJ weaving. You may feel warned, here is the solution

AopContext.currentProxy()

JavaDoc. I blogged about it here and here.
