i had same problem , found solution.

the problem class proxied (either @transactional or similar). spring cannot tell proxy instance of class, proxied interface.

i've found 2 solutions:

1. create interface personimport , @autowire instead of class.
2. use: proxy-target-class="true" in <tx:annotation-driven>
