$Proxy58 cannot be

Answer 1

I was writing unit tests and needed to be able to stub out the DAOs for some calls. Per This guys post: http://www.techper.net/2009/06/05/how-to-acess-target-object-behind-a-spring-proxy/ I used his method provided:

@SuppressWarnings({"unchecked"})
protected  T getTargetObject(Object proxy, Class targetClass) throws Exception {
  if (AopUtils.isJdkDynamicProxy(proxy)) {
    return (T) ((Advised)proxy).getTargetSource().getTarget();
  } else {
    return (T) proxy; // expected to be cglib proxy then, which is simply a specialized class
  }
}

Then you can easily call it with the proxy and get the object behind the proxy and manipulate the objects in it directly as needed.
