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);     } } 

Answer 1

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.

Answer 2

AopContext.currentProxy() as suggested by Tomasz will work. A more generic solution, that will work outside of the proxied class is to cast the object to org.springframework.aop.framework.Advised and get .getTargetSource().getTarget()

The former (getting the real object from the proxied object) is something that you should not really need. On the other hand getting the target proxy might be useful in some utility class that inspects existing beans in order to add some feature.
