How can I set Mockito `when` method when instantiating mock objects in Spring?

The method described in this answer best suits me for instantiating my mock objects.

However, I also need to set the Mockito when method(s).

Can I do that in the XML, or is the only way to to it like:

when(objectToBestTested.getMockedObject().someMethod(anyInt())).thenReturn("helloWorld");

within my test case?

The reason I ask, is because I don't otherwise need a getter for MockedObject, and I'd only be adding a getter so I can test ObjectToBeTested.
