Spring tries to autowire Mockito mocks

Question

I have a spring managed application in which I like for my service layer to be mocked. So I created a Spring Application Java Config and returned a mock of the actual service.

For e.g,

@Bean
@Profile("resource")
public MyService mockService() {
    return mock(MyService.class)
}

And then the MyService goes as

class MyService {

   @Autowired
   private MyDao dao;
}

When Spring creates bean of name "mockService", it also tries to Autowire MyDao on the mock ? This in my opinion defeats the purpose of mocking. Is this the expected behaviour, whats the workaround ?

So bottomline, its best practice to code to interfaces rather than concrete classes particularly if you are wanting to write focused tests on specific layers.
