[aspectj-users] Accessing original instance from introduction
|
Hi all,
I'm trying to intercept object deserialization when the object happens
to be an instanceof Serializable which is annotated with @Injected. In
order to do this I introduced an interface implementing readResolve(),
which is part of the deserialization protocol. Then I adviced this
introduced method. The advice is in fact executed upon
deserialization, but in that context 'this' is the introduced object,
not the one being deserialized (the one annotated with @Injected). I
need to get the list of methods of the original object in order to
inject dependencies on it, but I'm not able because I can only reach
the introduced one, which is a completely different one. Is there any
way to do this? Below is the related code. Any help would be very
appreciated.
Regards

public class InjectorAspect {
@After("execution(*
InjectorAspect.DeserializationSupport+.readResolve()) &&
this(injected)")
public void afterDeserialization(Object injected) {
injector.injectAll(injected); // <--- HERE injected is
DeserializationSupportImpl, not @Injected !
}
@DeclareParents(value="@Injected java.io.Serializable+",
defaultImpl=DeserializationSupportImpl.class)
private DeserializationSupport deserializationSupport;
public interface DeserializationSupport extends Serializable {
public Object readResolve() throws ObjectStreamException;
}
public static class DeserializationSupportImpl implements
DeserializationSupport {
public Object readResolve() throws ObjectStreamException {
return this;
}
}
}
