Is it possible to unproxy a Spring bean?

Question

I have a Spring bean, let\'s say:

@TransactionAttribute(TransactionAttributeType.REQUIRED) 
public class AImpl implements A {

     public void setSomeDepend         


        

Answer 1

Try this:

if(AopUtils.isAopProxy(a) && a instanceof Advised) {
    Object target = ((Advised)a).getTargetSource().getTarget();
    AImpl ai = (AImpl)target;
}

Bonus: in Scala I am using the following equivalent function for the very same purpose:

def unwrapProxy(a: AnyRef) = a match {
    case advised: Advised if(AopUtils.isAopProxy(advised)) => 
                            advised.getTargetSource.getTarget
    case notProxy => notProxy
}

Answer 2

With the introduction of Spring 4.2.RC1, there is now a dedicated utility class in the spring-test module that handles this case for you.

The class is called AopTestUtils and provides the methods:

• getTargetObject (unwraps only the top-level proxy)
• getUltimateTargetObject (unwraps multiple levels of proxies if they exist).
