How do I get the underlying type of a proxy object in java?

Question

I\'d like to access the classname of the underlying class which is an instance of java.lang.reflect.Proxy.

Is this possible?

Answer 1

I found a good solution on this site (now archived):

@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
  }
}

Usage

@Override
protected void onSetUp() throws Exception {
  getTargetObject(fooBean, FooBeanImpl.class).setBarRepository(new MyStubBarRepository());
}
