I actually never heard that? Where did you see that?
Which abstraction layers do you actually mean?
The Template is just an implementation of the Template Method design pattern which is used a lot and not an anti-pattern. Now I wouldn't extend the DaoSupport class because that couples my code to Spring, but not an anti-pattern either.
