If a method of service is marked as @Transactional with propagation nested, and inside it there are many calls to other @Transactional methods, each one of these methods will use its own session? It should represent many connections to db for just one method call no?

It looks like PROPAGATION_REQUIRED is better option for your purpose. From its javadoc:
Support a current transaction; create a new one if none exists.

Sorry maybe I wasn't clear but it's just curiosity, I always use default propagation of Spring, so I always have only on transaction (the outer one). But the q – ilopezluna Nov 27 '14 at 17:39

yes so using propagation you can give multiple recursive calls to the transaction you no need to worry for that :) – Harshal Patil Nov 27 '14 at 17:42

yes but my question was about sessions, what about this recursive calls getting sessions? it means that calling one method it could use N connections to db? – ilopezluna Nov 27 '14 at 20:22
